CTRIO(2) modules are programmable
high-speed discrete I/O modules that
accept signals from encoders and
discrete devices such as limit switches,
and generate precision output signals
for stepper control or other motionrelated discrete functions. CTRIO(2)
modules are coprocessors, having
H0-CTRIO(2) H2-CTRIO(2)
H4-CTRIO
T1H-CTRIO
their own scan time and their own
configurations. They have their own run mode and program mode, independent of the base
controller.
NOTE: For ease of documentation purposes, CTRIO will be used to designate all four CTRIO modules (H0CTRIO(2), H2-CTRIO(2), H4-CTRIO and T1H-CTRIO) when the functionality and/or description applies to all
four modules.
NOTE: The T1H-CTRIO is only supported by the T1H-EBC, T1H-EBC100 and T1H-PBC.
CTRIO Workbench
CTRIO Workbench is the utility used to configure the many functions available (listed
below) for a CTRIO(2) module. CTRIO Workbench is used in one of two ways, depending
on the base controller:
• Do-more: CTRIO Workbench is an
integrated utility of Do-more Designer.
The configuration becomes part of the
CPU project and is stored in the CPU.
The CPU will push the configuration to
the installed CTRIO(2) module as
appropriate.
• Any other base controller: CTRIO
Workbench is a separate utility that
communicates with a CTRIO(2)
module through the base controller to
configure the CTRIO(2). The
configuration is stored in the CTRIO(2)
and is a file that should also be stored on
your computer. Configuring the
CTRIO(2) is a process separate from
programming the base controller.
CTRIO Configuration
The CTRIO(2) module configuration created with CTRIO Workbench will define the
following:
Inputs:
1. Assign the input points
• Quadrature encoder with AB or ABZ
• Tachometer
Counter I/O User Manual, 2nd Ed., Rev. D
Chapter 1: Introduction
• Discrete (unassigned)
2. Functions applied to discrete inputs
• Simple discrete input
• Pulse catch (high-speed discrete input with programmable filter)
• Timing: edge timer (period), dual edge timer (time difference of two inputs)
• Reset counts (Z input from encoder)
• Capture counts (copy counts to a register)
• Inhibit counting
3. Scaling of timing functions or encoder inputs
Outputs:
1. Assign the output points
• Stepper control: Step/Direction or CW/CCW
• Discrete
2. Pulse profiles for stepper outputs to follow
• Trapezoid, S-curve, Symmetrical S-curve, Dynamic Position, Dynamic Velocity, Home
• Dynamic Position Plus, Trapezoid Plus, Trapezoid with Limits (CTRIO2 only and CTRIO
• Workbench v2.2.0 required)
3. Associate output functions with inputs
• Programmable Limit Switch or ‘PLS’ (CTRIO2 only and CTRIO Workbench v2.2.0
• required)
• Preset tables
CTRIO Functions
As mentioned above, the CTRIO(2) module supports five primary input functions: Counter,
Quad Counter, Pulse Catch, Edge Timer, and Dual Edge Timer.
Three secondary input functions are also supported. These functions, Reset, Capture, and
Inhibit, each modify the primary input functions in some way. Information is available about
each of the primary and secondary functions in chapter 4.
The CTRIO module supports three primary output functions: Pulse train output for
servo/stepper motor control, configurable for CW/CCW or step and direction, discrete
output functions assigned to Counter/Timer input functions, and raw output control directly
from the CPU interface program. Information is available about each of the output functions
in chapter 5.
NOTE: Before a CTRIO(2) will do anything, it must be configured, in run mode, and the memory must be
mapped. Mapping the memory is not required when used with a Do-more CPU.

Systems for the CTRIO Modules
6 Support
The CTRIO modules are compatible with several CPU-slot interfaces. Consideration must
be given to the firmware versions of the CPU-slot interfaces to assure their compatibility with
7
the CTRIO. (See Chapter 2 for CPU/CTRIO compatibility listings). Multiple CTRIO
modules can reside in the same base provided that the backplane power budget is adequate.

Installing the H0-CTRIO(2) Module
2-2
The H0-CTRIO(2) module is compatible with DirectLOGIC DL05 and DL06 PLCs.
Consideration must be given to the firmware versions of the PLCs to assure their
compatibility with the H0-CTRIO(2). (see chart below).
The H0-CTRIO(2) module plugs into any option card slot of any DL05 and DL06 PLC.
For installation instructions, refer to the:
• DL05 or DL06 User Manual (D0-USER-M or D0-06USER-M)
The first time you power-up the CTRIO module, you should see the OK LED blinking. The
blinking LED indicates that the module is in program mode.

Setting H0-CTRIO(2) Jumpers
The module’s internal jumpers must be set to the High Side Common position for high side
switching (sourcing) outputs or to the Low Side Common position for low side switching
(sinking) outputs. The sink/source jumper selection sets both outputs to the same option.
Source operation is the factory default setting.

The H0-CTRIO(2) module has one input channel, consisting of 4 optically isolated input
points (pts. A-D on common M). The inputs can be wired to either sink or source current.
The module has 2 optically isolated output points (pts. Y0-Y1 on common YC). The outputs
can be wired to either sink or
source current, but the
sink/source jumper selection
sets both outputs to the same

using CTRIO Workbench, to
accommodate the user’s
application. The function of
each input (counting, timing,
reset, etc.) and output (pulse output, discrete output, etc.) is defined in the configuration of
the module.
Refer to Chapters 4 and 5 to determine what input and output configurations are possible.

NOTE: Field device wiring must be compatible with the module configuration.
See the notes below for further details about power source considerations, circuit polarities,
and field devices. Also, refer to the specifications on pages 1-5 and 1-6 for more information.
NOTES:
1. Inputs (A, B, C, and D) require user-provided 9-30VDC power sources. Terminal M
is the commons for the inputs. Maximum current consumption is 12mA per input
point.
2. Polarity of the input power sources (shown above) can be reversed. Consideration
must be given, however, to the polarity of the field device. Many field devices are
designed for only one polarity and can be damaged if power wiring is reversed.
3. The maximum allowable current per output circuit is 1A.

Chapter 2: Installation and Field Wiring
Installing the H2-CTRIO(2) Module
The H2-CTRIO(2) module is compatible with Do-more CPUs and several DL205 CPU-slot
interface devices. Consideration must be given to the firmware version of the CPU to assure
their compatibility with the H2-CTRIO(2). (see chart below).
The H2-CTRIO(2) module plugs into any I/O slot of any Do-more or DirectLOGIC 205
base except slot 0 when using a DirectLOGIC PLC. Slot 0 is also not allowed if using the H2CTRIO and a WinPLC or H2-PBC controller. However, slot 0 is available for the H2CTRIO(2) module when using the H2-EBC interface devices (Slot 0 is the I/O slot adjacent
to the CPU). The H2-CTRIO(2) cannot be used in DL205 local expansion bases or in Serial
Remote I/O bases.
For installation instructions, refer to the:
• DL205 User Manual (D2-USER-M) if using a DirectLOGIC PLC
• DL205 Installation and I/O Manual (D2-INST-M) if using a WinPLC, EBC,
• Profibus slave interface module
• Do-more H2 series PLC Harware User Manual (H2-DM-M) if using a Do-more PLC
The first time you power-up the CTRIO module, you should see the OK LED blinking. The
blinking LED indicates that the module is in program mode.

Wiring the H2-CTRIO(2) Module
The H2-CTRIO(2) module has two independent input channels, each consisting of 4
optically isolated input points (pts. 1A-1D on common 1M and pts. 2A-2D on common
2M). The inputs can be wired to either sink or source current.
The module has 4 optically isolated output points (pts. Y0-Y3 with isolated commons
C0-C3, respectively). The outputs must be wired so positive current flows into Cn terminal
and then out of the Yn terminal (see the diagram below and the schematic on page 2-19).

NOTE: Field device wiring must be compatible with the module

considerations, circuit polarities, and field devices.
NOTES:
1. Inputs (1A, 1B, 1C, 1D and 2A, 2B, 2C, 2D) require user-provided 9-30VDC power
sources. Terminals 1M and 2M are the commons for Channel 1 and Channel 2
inputs. Maximum current consumption is 12mA per input point.
2. Polarity of the input power sources (shown above) can be reversed. Consideration
must be given, however, to the polarity of the field device. Many field devices are
designed for only one polarity and can be damaged if power wiring is reversed.
3. Outputs have one polarity only (as shown above) and are powered by user-provided
5-36VDC power sources. The maximum allowable current per output circuit is 1A
for the H2-CTRIO and 1A at 23°C or 0.5A at 60°C for the H2-CTRIO2.

Installing the T1H-CTRIO
2-28
The T1H-CTRIO module is compatible with several Terminator I/O Network interface
devices. Consideration must be given to the firmware versions of the Network interfaces to
assure their compatibility with the T1H-CTRIO. (see chart below).
The T1H-CTRIO module plugs into any valid I/O slot in a Terminator I/O system. The
T1H-CTRIO cannot be used in Serial Remote I/O bases (T1K-RSSS).
For installation instructions, refer to the:
• Terminator I/O Installation and I/O Manual (T1K-INST-M)
The first time you power-up the CTRIO module, you should see the OK LED blinking. The
blinking LED indicates that the module is in program mode.

Chapter 2: Installation and Field Wiring
Wiring the T1H-CTRIO Module
The T1H-CTRIO module has two independent input channels, each consisting of 4 optically
isolated input points (pts. 1A-1D on common 1M and pts. 2A-2D on common 2M). The
inputs can be wired to either sink or source current.
The module has 4 optically isolated output points (pts. Y0-Y3 on isolated commons C0-C3,
respectively). The outputs must be wired so that positive current flows into Cn terminal and
then out of the Yn terminal. (see the diagram on the following page and the schematic on
page 2-34)
The module is configured, using CTRIO Workbench, to accommodate the user’s application.
The function of each input (counting, timing, reset, etc.) and output (pulse output, discrete
output, etc.) is defined in the configuration of the module.
Refer to Chapters 4 and 5 to determine what input and output configurations are possible.
NOTE: Field device wiring must be compatible with the module configuration.
See the notes below for further details about power source considerations, circuit polarities,
and field devices. Also, refer to the specifications on pages 1-5 and 1-6 for more information.
Apply the labels that come with the I/O module to the I/O
base terminals to properly identify the base terminal points.

NOTES:
1. Inputs (1A, 1B, 1C, 1D and 2A, 2B, 2C, 2D) require user-provided 9-30VDC power sources.
Terminals 1M and 2M are the commons for Channel 1 and Channel 2 inputs. Maximum
current consumption is 12mA per input point.
2. Polarity of the input power sources can be reversed. Consideration must be given, however, to
the polarity of the field device. Many field devices are designed for only one polarity and can
be damaged if power wiring is reversed.
3. Outputs have one polarity only and are powered by user-provided 5-36VDC power sources.
The maximum allowable current per output circuit is 1A.

To configure the CTRIO module Online, a CTRIO must be installed in the PLC base or
Terminator I/O system, and the system power must be on. Your PC communicates with the
CTRIO module through the PLC or interface device port.
DirectSOFT5 Users
You will need to connect your PC to the CPU,
DCM or ECOM module. If you are linked to your
CPU through DirectSOFT5, CTRIO Workbench
will start via the existing link. If you are
“disconnected” from your PLC and start CTRIO
Workbench, you will be prompted to establish a link
to your CTRIO module.
DirectSOFT5 users will find CTRIO Workbench in the
DSLaunch Window’s Utilities section.
WinPLC, EBC and PLC>ERM>EBC Users
You will need to connect your PC to the RJ45 Ethernet port on
the WinPLC or EBC interface device directly or via hub,
switch,etc. (Connect to the ST-style fiber optic port on the HxEBC-F units.)
Access the WinPLC and EBC support version at
Start>Programs>AutomationDirect Tools>CTRIO Workbench
or in the DirectSOFT5 Launch Window Utilities menu. Then
select the appropriate Workbench version.
You will be prompted to establish an Ethernet link to
your CTRIO module.
NOTE: WinPLCs will need to be given an IP address before
connecting with Workbench.
EBCs will need to have an address selected by DIP Switch or
via NetEdit before connecting with Workbench.
Counter I/O User Manual, 2nd Ed., Rev. D
Chapter 3: Introduction to CTRIO Workbench
PBC, DEVNETS and MODBUS Users
You will need to connect your PC to the RJ12 serial port on
the PBC, DEVNETS or MODBUS interface device.
Access the various support versions at
Start>Programs>AutomationDirect Tools>CTRIO
Workbench or in the DirectSOFT5 Launch Window
Utilities menu. Then select the appropriate Workbench
version.
You will be prompted to establish a serial link to your
CTRIO module.
Select the PC serial port Workbench will use to
connect to the CTRIO module.
Successful On-line Connection
Once you are connected to your CTRIO module, you will enter the main window of
CTRIO Workbench. Here, you select the CTRIO module you wish to configure by clicking
on its slot number in the “Installed Modules” box. You will be able to enter Workbench’s
Configuration dialog, and after successfully configuring the module you will be able to toggle
the CTRIO module between Program Mode and Run Mode and enter the Monitor I/O
dialog.

Module Modes of Operation
On the CTRIO Workbench main window, a single button toggles
between Run Mode and Program Mode. The Module Mode
indicator will tell you which mode your module is in. You can
make configuration changes in either Run Mode or Program
Mode, but to save your configuration to the module, you must
click “Write Module” which is only active in Program Mode.
In the lower left corner of the main Workbench dialog, is the
Config Status indicator. If the current configuration is different
from the CTRIO and different from any saved files, the indicator
will display the word “Changed.” If the current configuration has
been written to the module or a file, the message will read “Same
as Module,” “Same as File,” or “Same as Both.”
Program Mode - Configuring the CTRIO Module
After the configuration is created or changed in CTRIO Workbench, it must be “written” to
the CTRIO module. This is accomplished by returning to
the main CTRIO Workbench window and clicking on
“Write Module.”
If the configuration was created using Workbench Offline
version, you must connect your PC to the CTRIO module
through the CPU/controller and write the configuration to
the module.
NOTE: Entering program mode takes the CTRIO module offline. Input pulses are not read or
processed in Program mode, and all outputs are disabled. CPUs will hold last value in memory while
the CTRIO is in Program Mode.
Run Mode - Start Processing I/O Pulses with the CTRIO Module
Selecting Run Mode causes the CTRIO module to begin processing pulses based on the I/O
configuration you created.
In Run mode the CTRIO Workbench utility also allows you to monitor and verify the
proper operation of inputs and outputs. You can see the count change, reset, etc. using the
Monitor I/O dialog. Monitor I/O is very useful for debugging and commissioning of a new
system. See chapter 7 for information on Monitor I/O.
The CTRIO mode follows the CPU mode. If the CPU is placed in Run Mode, the CTRIO
module will also enter Run Mode. If the CPU is placed in STOP or PROGRAM Mode, the
CTRIO will enter Program Mode. The CTRIO also responds to mode changes made in
Workbench and can be placed in Run Mode while the CPU is in Stop or Program Mode.
The CTRIO module responds to the most recent change whether performed in Workbench
or from the CPU.
NOTE: The CTRIO module will not enter Run Mode if it does not have a valid configuration.

Now the Edit CTRIO/CTRIO2 Configuration window should be open, click the “Configure
I/O...” button.
You should now have the Configure
I/O window open, similar to the one
shown here, with a tab for each input
Channel.
The input options are listed by
function. Four boxes labeled A, B, C,
and D correspond to the input
terminals on the face of the module
(1A-1D or 2A-2D; A-D for the H0CTRIO(2)).
The Output functions are listed as 0,
1, 2, and 3. These numbers
correspond to the markings beside the
module’s output terminals (Y0-Y3; Y0Y1 for the H0-CTRIO(2)).
Counter I/O User Manual, 2nd Ed., Rev. D
Chapter 4: Configuring the CTRIO Inputs
For DirectLOGIC users, be sure to write the changes to the module from Workbench when
the configuration is complete. For example, you might click on “Counter” in the “A” box,
then OK to return to the main Workbench window. Once you arrive back at the main
window, you must click “Write Module” to save your selection to the module. The module
will need to be in Program Mode to perform the Write Module operation. If you do not
perform the Write Module operation (or a Write File operation) your configuration will be
lost upon quitting Workbench. This applies to all changes to the module configuration.
For Do-more users, the “Write Module” button does not exist because the Module
Configuration dialog stores the CTRIO's configuration as a permanent part of the Do-more
controller's System Configuration.
Input Function Selections
Supported Functions
The input channels offer the same configuration options. The module supports five primary
input functions:
• Counter
• Quadrature Counter
• Pulse Catch
• Edge Timer
• Dual Edge Timer
Each of the primary functions uses one or two input terminals for making connections to
field devices (plus a common). Combinations of the listed functions are possible. The
configuration dialog disallows any unsupported configurations.
Three secondary input functions are also supported:
• Reset
• Capture
• Inhibit
Each secondary input modifies the primary input functions in some way and uses one input
terminal. (Limit Out 0 and Limit Out 2 input functions are only available for use when the
outputs are set to pulse output mode).
Discrete Outputs Pre-Assigned to Input Functions
CTRIO discrete outputs can be assigned to the Counter, Timer and Pulse Catch input
functions within the Configure I/O dialog. The outputs respond to presets assigned by the
user in the Preset Tables dialog. The presets are assigned based on the scaled value of an input,
or the raw value if it has no scaled value. The CTRIO’s four outputs can all be assigned to one
function, or they can be grouped within functions and within channels in any manner
selected by the user. See Chapter 5 for more information on using Preset Tables.

The CTRIO module supports up or down counting using single-ended encoders (or other
single-ended pulse sources) as inputs. Encoders, proximity
A
sensors, etc., can be connected to input A and/or input B
on either channel or both channels. The C and D inputs
are available to modify the A and B inputs. The C and D
inputs can be used for Reset, Inhibit, or Capture. These
functions are explained later in this chapter. The CTRIO
discrete output(s) can be assigned to the Counter function
using the Preset Tables dialog. Refer to “Creating and Using

The module’s four input terminals are represented by the A,
B, C, and D boxes on the left side of this dialog. If you are
wiring your counter input to terminal 1A, you will want to
select the Channel 1 tab near the top of this window and click “Counter” in box A.
At this point, you have four decisions to make regarding your input at 1A.
1. Select count up or count down. A button, in the Function 1 box, toggles between Up and Down
counting. Click the button labeled “Up” (or “Down”) to see the change to the opposite count
direction.
2. Each input pulse is counted, but you are free to
designate whether you want the count to register
on the rising edge of the pulse, the falling edge, or
both. The button with the graphical
representation of a pulse toggles between these
choices.
3. The Reset value is assigned by clicking and
typing a value in the data input field. This value is
for hardwired resets. When the hardwired reset is
activated, the count value returns to the reset
value.
4. The last remaining decision to be made is about
scaling. Clicking the button with the ruler symbol
starts the Scaling Wizard. We discuss the scaling
wizard later in this chapter. The Scaling Wizard is
intelligent in that it offers scaling options that are appropriate for your input selections.

Quad Counter
The CTRIO module supports quadrature counting
using quadrature encoders as inputs. Connect your
encoder to input A and input B on either channel. A
second quadrature encoder can be connected to the
other channel. The C and D inputs are available to
control the quadrature input counting. The C and D
inputs can be used for Reset, Inhibit, or Capture.
These functions are explained later in this chapter.
The CTRIO discrete output(s) can be assigned to the
Quad Counter function using the Preset Tables dialog.
Refer to “Creating and Using the Output Tables”

If you are wiring your quadrature counter
inputs to terminal 1A and 1B, you will
need to select the Channel 1 tab near the
top of this window and click “Quad
Counter” in box A. Notice that input B is
now slaved to input A.
At this point, you have three decisions to
make regarding your quadrature input.
1. A multiplier can be applied to the
quadrature input to increase its resolution. Select “1x”, “2x”, or “4x.” [1X = pulses processed on
leading edge of input A, 2X = pulses are processed on both edges of input A, 4X = pulses processed
on both edges of input A and both edges of input B.]
2. The “Reset Value” is assigned by clicking in the data input field and typing in a value. When the
count is reset, using any of the reset methods, the count value returns to the Reset Value. The reset
options are described in more detail later in this chapter.
3. The last remaining decision to be made is about scaling. Clicking the button with the ruler symbol
starts the Scaling Wizard. The Scaling Wizard is intelligent in that it offers only those scaling options
that are appropriate for your input selections. We discuss the scaling wizard in greater detail later in
this chapter.

Pulse Catch
4–8
The CTRIO “Pulse Catch” function allows a very short duration pulse to be qualified and
lengthened to a time period long enough to guarantee that it is seen by the CPU. CPU scans
necessarily vary with the length and complexity of the user’s program. A scan frequency of
several milliseconds, or more, is common. A pulse that lasts less than one millisecond, is
typically hard to catch during the CPU scan.
The CTRIO module’s Pulse Catch function sees the fast incoming signal and holds its status
in a status bit until the CPU can see it. A
discrete output(s) can also be tied to
follow the Pulse Catch input.
NOTE: To insure proper operation, the field
device wiring and the configuration must be
compatible. For wiring information see
Chapter 2.
Notice that the module’s four input
terminals are represented by the A, B, C,
and D boxes on the left side of this
dialog. If you are wiring your input to
terminal 1C, you will need to select the
Channel 1 tab near the top of this
window and click Pulse Catch in box C.
Three selections must be made in
conjunction with the Pulse Catch option.
1. First, a decision must be made whether to look for the rising edge of the pulse or the falling edge
of the pulse. This is a critical decision. Careful attention should be paid to the type of output the
field device generates. If the signal voltage is normally low, but a short duration pulse sends the signal
to the ON state, you will want to trigger off the rising
edge, and vice versa.
2. The second decision you will need to make is the
minimum pulse width you want to capture. Transients
below this width will not be recorded. Set this value by
typing the desired value in the “Minimum Width In”
field.
3. The final decision to be made is the length of pulse
the CTRIO module should send in response to the
input pulse. Make this setting by typing in the desired
value in the “Pulse Out Width” field.

the Channel 1 tab near the top of this window and click Edge Timer in box C.
At this point, you have four decisions to make regarding your input at 1C.
1. First, designate the pulse edges you want
to measure between. There are four choices.
You can measure the time from the leading
edge of the upward pulse to the leading
edge of the next upward pulse, or from the
trailing edge of an upward pulse to the
trailing edge of the next upward pulse, or
from the leading edge of an upward pulse
to the trailing edge of the same pulse, or,
finally, from the leading edge of a
downward pulse to the trailing edge of the
same downward pulse.
The last option could be restated as timing
from the trailing edge of an upward pulse to the rising edge of the next upward pulse.
2. The “Free Run” option is assigned by clicking in the appropriate box. If your application calls for
velocity measurements to be taken at the commencement of some event, do not use Free Run. If your
application calls for velocity measurement on a continuous (moving average) basis, you should use
Free Run.
3. The “Enable Timeout” option is assigned by clicking in the appropriate box and specifying a
Timeout period. Once the timer is enabled, the Timeout Bit is set if the time that it takes the CTRIO
to see the configured input edge exceeds the specified Timeout Period. Also, if the time before the
CTRIO sees the next configured edge exceeds the specified Timeout Period, the Timeout bit is set.
More information about the Timeout function can be found in chapter 6.
4. The last remaining decision to be made is about scaling. Clicking the button with the tape measure
symbol starts the Scaling Wizard. We discuss the scaling wizard later in this chapter. The Scaling
Wizard is intelligent in that it offers scaling options that are appropriate for your input selections.

Reset 1 and Reset 2 (Hard Resets for Counters Only)
“Reset 1” is available only if you have selected a Counter or Quad Counter as the primary
function. For example, if you have chosen either counter function (single-ended or
quadrature) on terminal 1A, you will have an option of using terminal 1C for a hard reset
signal. Other options are available on
terminal 1D. Those options are
Capture and Inhibit (see next page).
Reset 2 is available if you have
selected to use terminal 1B for a
counter input. Reset 2 will reset the counter
connected to terminal 1B.
Two distinct types of hard resets are available. One is
an edge reset. The other is a level reset. The Edge

Reset sets the current count to zero on the specified
edge (rising or falling) of the reset pulse (see upper
example). The Level Reset resets the count to zero (as
long as the reset pulse is held high (or low depending
on configuration). When the reset pulse disappears,
Edge Reset
the count resumes (see lower example).
If the Reset options are not available in the Configure

Introduction to the Scaling Wizard
Scaling raw signals to engineering units is
accomplished using the Scaling Wizard. Start
the Scaling Wizard by clicking the ruler button
on the Configure I/O dialog. This button
appears only after you select one of the Counter
or Timer functions.
The Scaling Wizard options are different for
the Counter functions as compared with the
Timer functions. “Position” and “Rate” scaling
are available when you select a Counter
function. “Interval” scaling is available when
you select a Timing function.
We will step through the dialogs used for each scaling type. Substitute appropriate values to
set up scaling for your application.
Scaling Wizard Examples for Counter Functions
On the counter Scaling
Wizard, you can select None,
Position, or Rate. No scaling is
accomplished if the None
button is selected. Position
scaling is appropriate for
measuring distance, position,
or size. Rate scaling is
appropriate for velocity, RPM,
flow, or similar rate based
measurements. You may want
to read the Notes and other
information before leaving this
window.

Position Scaling (Counter)
To select Position Scaling, click the radio button beside the word Position.
Now, click Next to move to the Output Settings dialog.
On the Output Settings dialog, you will notice
the field for engineering units. Enter an
appropriate value for Position Scaling, for
example yards, feet, meters, cubic inches, etc.
Seven data types are available including BCD
(to make values more easily used by
DirectLOGIC PLCs).
Click Next, to open the Position Settings
dialog. It is here that you enter the span of raw
counts that equates to a span of engineering
units.
This window contains a calculator to double check
the meaning of your Position Settings. Enter a
value into the Raw Value field to see the equivalent
value in engineering units.

Rate Scaling (Counter)
To select Rate Scaling, click the radio button beside the word Rate. Now,
click Next to move to the Output Settings dialog.
On the Output Settings dialog, you will
notice the field for engineering units. Enter an
appropriate value for Rate Scaling, for
example RPM, fps, flow, etc. Seven data types
are available including BCD (to make values
more easily used by DirectLOGIC PLCs).
Click Next, to open the Rate Settings dialog.
It is here that you enter the counts per unit
of time and the time base. A scale offset is
also provided to adjust the result by a
constant amount.
This window contains a calculator to double
check your Rate Settings. Enter a value into
the Raw Value field to see the equivalent
value in engineering units.
As an example, let’s say you have a 1,000
pulse/revolution encoder, and you want to
use it to measure RPM (of the encoder
shaft). You would enter “1,000” for the
Counts/unit and “minutes” as the Time Base.
A check using the calculator (over a sample
time of 1,000 ms = 1 second) reveals that
5,000 counts equals 300RPM.
5000 counts/1000 counts per rev = 5 revolutions;
5 revolutions/1 sec x 60 sec/1 minute= 300 RPM
Data Smoothing allows rolling averages to be taken to calculate a value.
Min = 1 sample, max = 25 samples in the rolling average.

Configure I/O Dialog Overview
5–2
The Configure I/O dialog is the location where input and output functions are assigned to
the module. The choice of input and output functions determines which options are
available.
The input and output function boxes prompt you with selections for supported functions.
The configuration software disallows any unsupported selections.
For DirectLOGIC users, from the main CTRIO Workbench
window, click on the “Go to PROGRAM Mode” button (if in
RUN Mode). Then, click on the “Config I/O” button to arrive at
a dialog shown below. Notice that the window has a tab for each
input Channel. Channel 1 and Channel 2 offer the same
configuration options. Remember that the H0-CTRIO(2) only has one input channel.

You should now have the Configure
I/O window open, similar to the one
shown here, with a tab for each input
Channel.
The input options are listed by
function. Four boxes labeled A, B, C,
and D correspond to the input
terminals on the face of the module
(1A-1D or 2A-2D; A-D for the H0CTRIO(2)).
The Output functions are listed as 0,
1, 2, and 3. These numbers
correspond to the markings beside the
module’s output terminals (Y0-Y3; Y0Y1 for the H0-CTRIO(2)).

Chapter 5: Configuring the CTRIO Outputs
For DirectLOGIC users, be sure to write the changes to the module from Workbench when
the configuration is complete. For example, you might click on “Discrete Output” in the “0”
box, then OK to return to the main Workbench window. Once you arrive back at the main
window, you must click “Write Module” to save your selection to the module. The module
will need to be in Program Mode to perform the Write Module operation. If you do not
perform the Write Module operation (or a Write File operation) your configuration will be
lost upon quitting Workbench. This applies to all changes to the module configuration.
For Do-more users, the “Write Module” button does not exist because the Module
Configuration dialog stores the CTRIO's configuration as a permanent part of the Do-more
controller's System Configuration.
Output Function Selections
Supported Functions
The module supports four output functions:
• Raw
• Pulse (Step/Direction)
• Pulse (CW/CCW)
• Discrete Ch(1,2)/Fn(1,2)
Each function uses one or two output terminals for making connections to field devices (plus
a common). Combinations of the listed functions are possible. The configuration dialog
disallows any unsupported configurations.
CTRIO Memory Usage: Pulse Profiles and Preset Tables
CTRIO configuration software can create a maximum of 255 predefined Pulse Profiles. The
total number of Pulse Profiles available is 255 minus the number of predefined Preset Tables.
Pulse Profiles and Preset Tables are saved as File 1 through File 255. The module has 256
Total Blocks of memory allocated for Pulse Profiles and Preset Tables usage. The number of
memory blocks used varies between Pulse Profiles and Preset Tables.

The CTRIO module supports Raw output mode. This mode
allows the CPU/controller program to have direct access to the
module’s output points. Each output can be configured for Raw
output mode and each will have a unique control bit.

Chapter 5: Configuring the CTRIO Outputs
Discrete Outputs
The CTRIO module has four discrete outputs numbered Y0-Y3 (Y0-Y1
for the H0-CTRIO(2)). The outputs respond to presets assigned by the
user in the Configure I/O dialog.
The presets are assigned based on the scaled value of an input, or the
raw value if it has no scaled value. The four outputs can all be assigned
to one function, or they can be grouped within functions and within
channels in any manner selected by the user.
To assign output presets, begin by selecting the ouput on the Configure
I/O dialog. The outputs are identified based on terminal number. In the
example to the right, output terminal “0” is designated for a discrete
output.
Once the output selection is made, a new button
appears on the Configure I/O dialog. The button is
labeled as shown to the right. The leading numeral
represents the number of the output terminal. Clicking on the Preset
button causes the Default Output Settings dialog to pop up. Default
settings are loaded on power-up.
On the Output Settings dialog, select “Use Single Preset.” We will
discuss Preset Tables later in this
chapter. Now, click OK to arrive at
the Edit Preset Entry dialog.
Six output functions are available (as shown in the figure
below). Set the preset value in engineering units if the
signal has been scaled. Set the preset value in raw count if
the signal has not been scaled. We discuss scaling in
chapter 4. Pulse ON and Pulse OFF require a Pulse Time
setting. The Pulse Time is set in msec (1,000 sec = 1 msec)

Creating and Using the Programmable Limit Switch (CTRIO2 only)
A Programmable Limit Switch (PLS) is a discrete output table used to turn an output ON or
OFF at multiple points across an input’s range.
The PLS function is only available in the Hx-CTRIO2. A PLS table must be created in the
CTRIO module configuration. Once created, it can be edited using the configuration
application or for Do-more systems, it can be edited using the PLS instructions in ladder. For
greater flexibility when using Do-more systems, create PLS tables in the CTRIO module
configuration then populate their entries (up to 128) from ladder. If using the ladder
instructions, run them after a power cycle to regenerate the tables.
To use a PLS table, an output must be configured as a discrete output paired with a counter
or timer input function. For example, Channel 1 inputs A and B could be configured for
quadrature counting, which would be Channel1Function1. Output 0 could be configured as
Discrete on Ch1/Fn1. When a PLS table is loaded for Output 0, the CTRO2 will monitor
the input value for Ch1/Fn1 (Channel1 quad counter) and Output 0 will be the output
turned ON and OFF by the table.
NOTE: Since a CTRIO Output’s function is fixed in the configuration, an output cannot be changed
programmatically to reference a different input function. This specific change requires a configuration
change and project transfer.
To create a PLS table, from the EditCTRIO/CTRIO2 Configuration window click Discrete
Tables then select Add PLS Table (as seen on following page). Name the table and if the PLS
entries will be populated from ladder in Do-more, leave the table empty and click OK.
Otherwise, use the buttons on the right to build and modify a PLS table. If an input channel
has scaling, it will show in the Scales list, and entries can optionally be entered in scaled units
after selecting the appropriate entry in the Scales list.
Counter I/O User Manual, 2nd Ed., Rev. D
Chapter 5: Configuring the CTRIO Outputs
The table entries are very simple. Select a default value for the discrete output, the output will
be in this state if the input is not within a defined range. Add an entry for each range of input
values where the output should be in the opposite state.
NOTE: Unlike a preset table, events in a PLS table can occur in any order, even simultaneously.
In ladder, use the CTRIO Table Load (CTTBLLD) instruction to load the table for an
output. Loading the table could take multiple scans. When CTTBLLD’s On Success
indication becomes true, set the output’s .EnableOutput structure member to begin using the
table.
For more detailed information, see the Do-more Designer help file topics for CTRIO Module
Configuration, CTTBLADD, CTTBLCLR, CTTBLEDT and CTTBLLD.

Creating and Using the Output Preset Tables
Preset tables can be used only when the corresponding input is configured for a timer or
quad/counter that is not scaled or if a counter is set to Position scaling.
For DirectLOGIC users, click the
Preset Tables button on the main
Workbench dialog. This will open the
Output Preset Tables dialog. To create a new table, click
Add (or Edit). This will open the Edit Preset Table dialog.
For Do-more users, from the Edit CTRIO/CTRIO2
Configuration page, click the “Discrete Tables...” button.
This will open the Discrete Output Tables dialog. To
create a new table, click Add (or Edit). This will open the
Edit Preset Table dialog.
Build a Preset Table by adding preset entries one at a time.
Click Add Preset (or Edit Preset) to open the Edit Preset
Entry dialog.
NOTE: The preset tables work similiar to an event drum, not a programmable limit switch. For example, in
the Edit Preset Table dialog below, the output is SET at count 100. Once the output is SET, if the count
drops below 100, the output will not go OFF, it will remain SET. Once a step is complete, the focus is on the
next step and that step only.
On the Edit Preset Entry dialog, select one
of the six Output Functions. Set the preset
value in engineering units if the signal has
been scaled. Set the preset value in raw
count if the signal has not been scaled. We
discuss scaling elsewhere in this chapter.
Pulse ON and Pulse OFF require a Pulse
Time setting.
The Pulse Time is set in ms (1,000 ms = 1 sec). For a
description of the Output Functions see page 5-6.
To set a particular table as the default table, use the
Default Output Settings dialog described on page 5-6.

Chapter 5: Configuring the CTRIO Outputs
Using the Discrete Outputs in Level Mode
If a Counter or Timer function is scaled to produce a rate, alarm level settings can be used to
trigger discrete outputs at values predetermined by the user.
Click the Level button on the Configure I/O dialog. This will
open the Default Output Settings (Level Mode)dialog.
The alarm level is set within the Default Output
Settings (Level Mode) dialog.
Also, a deadband percentage (in tenths of a
percent) can be set to prevent the output from
changing too frequently (chattering) near the Rate
Level threshold.
“ON when greater” condition example:
Consider a Discrete Output set to turn ON when a
level gets to 500 rpm with a 10% deadband. The
output will turn ON when the level gets to 100. If
the level drops, the output will stay on until the
level drops below 450 rpm, where it will turn OFF.
“OFF when less” condition example:
Consider a Discrete Output set to turn “OFF when
less”at 500. When the level gets to 500, the output
turns OFF. If the level rises again, the output will
stay OFF until the level gets to 550, where it will
turn ON.

The CTRIO module offers up to two axes
of motion control (Y0 and Y1 as an axis
and/or Y2 and Y3 as an axis). The H0CTRIO(2) has one axis of motion control
(Y0 and Y1). The outputs can be
configured for CW/CCW, or step and
direction operation. The outputs respond
to profiles defined by the user and called
by the user control program. The
following pulse profiles are supported:
• Trapezoid
• S-Curve
• Symetrical S-Curve
• Dynamic Positioning
• Dynamic Velocity
• Home Search
• Free Form
• Dynamic Positioning Plus (CTRIO2)
• Trapezoid Plus (CTRIO2)
• Trapezoid w/ Limits (CTRIO2)
There are three additional pulse profiles that are
available to use that are not created using the Pulse
Ouput Profiles Tables. These profiles: Velocity Mode,
Run to Limit Mode and Run to Position Mode are
discussed at the end of this chapter.
Creating Pulse Output Profile Tables
For DirectLOGIC users, click the Pulse Profiles button
on the main Workbench dialog.
For Do-more users, click the
“Pulse Profiles...” button from

The Trapezoid Plus profile is only available when using an Hx-CTRIO2. See Trapezoid
description for a general description of this profile. The profile resembles Trapezoid Profile,
but has four additional features:
1. The target position is a variable (parameter 3) set by the base controller, instead of a
constant specified in the profile.
2. The profile can be asymmetrical. (Accel and Decel rates are separate)
3. Encoder Feedback can be added, useful for correcting excessive lash or slippage in the
system.
4. Allows output rates up to 250kHz.
When Use Encoder for Position is enabled, the target position is specified in units of the
encoder. Encoder feedback determines when deceleration of a move should begin and
determines when the move should stop. If Scale Factor is set incorrectly, the output could
overshoot the target position, or start decelerating too soon.
Minimum Freq: The frequency at which the profile will begin and end.
Maximum Freq: The maximum steady state frequency the profile can attain during a move.
Accel Rate: The rate at which the output frequency will increase at the start of the profile.
Decel Rate: The rate at which the output frequency will decrease at the end of the profile.
Encoder Input: Select the channel where the encoder is connected. The inputs for the
encoder (A&B) must be configured for Quad Counter.
Scale Factor: This is the output to input resolution (stepper/encoder) ratio. In other words,
if the stepper motor being used is a 1000 ppr (pulses per revolution) and the encoder is 800
ppr, then the scale factor would be 1000/800 = 1.25.
Deadband: This is the number of position counts away from the target position that causes
no action. This can reduce "hunting" or "ringing" as the profile attempts to get to the target
position. Be sure to include a deadband when the encoder has a higher resolution than the
stepper.

S-Curve Profile
The S-Curve profile can be used for applications that are sensitive to sudden changes in
position or velocity, resulting with vibrations or jerky reactions. The S-Curve profile provides
more controlled acceleration and deceleration periods than the Trapezoidal profile by
increasing the transistion times.
Total Pulses: The total amount of output pulses that will be generated during the
Trapezoidal profile.
Accel Time: The amount of time required for the Start Frequency to ramp up the Position
Frequency.
Decel Time: The amount of time required for the Position Frequency to ramp down to the
End Frequency.
Start Freq: The frequency at which the Trapezoidal profile will begin.
Pos Freq: The target frequency to which the Start Frequency rises.
End Freq: The frequency to which the Position Frequency falls.
Min Freq Change: The amount of calculated frequency change that must take place before
stepping to the next frequency.
Min Entry Time: The amount of time spent in each step.

The Symmetrical S-Curve profile can also be used for applications that are sensitive to sudden
changes in position or velocity, resulting with vibrations or jerky reactions. The Symmetrical
S-Curve provides more controlled acceleration and deceleration periods than a Trapezoidal
profile by increasing the transistion times.
The S-Curve and Symmetrical S-Curve profiles differ in that the Symmetrical S-Curve has
symmetrical acceleration and deceleration profiles. The Decel Time and End Frequency are
determined by the Accel Time and Start Frequency. The Symmetrical S-Curve uses less
memory than the S-Curve profile.
Total Pulses: The total amount of output pulses that will be generated during the
Trapezoidal profile.
Accel Time: The amount of time required for the Start Frequency to ramp up the Position
Frequency. This also represents the deceleration time.
Start Freq: The frequency at which the Trapezoidal profile will begin. This also represents the
end frequency.
Pos Freq: The target frequency to which the Start Frequency rises.

Dynamic Positioning Profile
The Dynamic Positioning profile is a trapezoidal profile with identical
acceleration/deceleration rates and identical starting/stoping frequencies. The maximum
target frequency is specified. The target position (# of output pulses) is located in a memory
register in the CPU/controller. Once the position is reached, the output is disabled and a new
target position can be specified in the memory register.
Accel Rate: The rate at which the Minimum Frequency will to ramp up the Maximum
Frequency. This sets the deceleration rate as well.
Minimum Freq: The frequency at which the profile will begin.

Dynamic Positioning Plus Profile
5–18
The Dynamic Positioning Plus profile is only available when using an Hx-CTRIO2. The
profile resembles Dynamic Position, but adds two features:
1. The profile can be asymmetrical. (Accel and Decel Rates are separate)
2. Encoder Feedback can be added, useful for correcting excessive lash or slippage in the
system.
When Use Encoder for Position is enabled, the target position is specified in units of the
encoder. Encoder feedback determines when deceleration of a move should begin and
determines when the move should stop.
See Dynamic Position for a general description of this profile.
Minimum Freq: The frequency at which the profile will begin and end.
Maximum Freq: The maximum steady state frequency the profile can attain during a move.
Accel Rate: The rate at which the output frequency will increase at the start of the profile.
Decel Rate: The rate at which the output frequency will decrease at the end of the profile.
Encoder Input: Select the channel where the encoder is connected.
Scale Factor: This is the output to input resolution (stepper/encoder) ratio. In other words,
if the stepper motor being used is a 1000 ppr (pulses per revolution) and the encoder is 800
ppr, then the scale factor would be 1000/800 = 1.25.
Deadband: This is the number of position counts away from the target position that causes
no action. This can reduce "hunting" or "ringing" as the profile attempts to get to the target
position. Be sure to include a deadband when the encoder has a higher resolution than the
stepper.

Dynamic Velocity Profile
The Dynamic Velocity profile is a trapezoidal profile with the direction acceleration and
deceleration rates specified. The target velocity is located in a memory register in the
CPU/controller. Once the CPU/controller initiates the profile, output pulses will be
generated at the target velocity until the CPU/controller disables the output pulses.
Clockwise Accel Rate: The clockwise rate at which the output will ramp up from 0pss to the
target velocity that is specified in the CPU/controller memory register.
Clockwise Decel Rate: The clockwise rate at which the output will ramp down from the

Counter-Clockwise Accel Rate: The counter-clockwise rate at which the output will ramp
up from 0pss to the target velocity that is specified in the CPU/controller memory register.

The Home Search profile is used to “find the home position”, which is usually a reference point
to which the object being moved can return upon command at any time during or after the
execution of a positioning profile.
There are several Home Search routines to choose from, all with the option to designate
whether you want Limit 1 and/or Limit 2 (a CTRIO discrete input) to register on the rising
edge, falling edge, high level or low level signal. Limit 1 and Limit 2 can be the opposite
edges of the same physical CTRIO input.
NOTE: The Home Search profile requires that CTRIO inputs C and/or D are configured for Limit Out 0 or
Limit 2. This is done using the Configure I/O dialog.
Frequency 1: The frequency at which the Home Search will begin.
Limit 1: Home Search Frequency 1 will run to CTRIO input Limit 1 and stop unless
Frequency 2 is enabled.
Frequency 2: (if enabled) Once Limit 1 is reached, the pulse output will continue at
Frequency 2 until CTRIO Limit 2 is reached or pulse Count is reached at Frequency 2.
Limit 2: (if enabled) Home Search Frequency 2 will run to CTRIO input Limit 2 and stop.
Count: (if enabled) The number of output pulse counts generated at Frequency 2 before
terminating.

Trapezoid with Limits Profile
5–22
The Trapezoid with Limits profile is only available when using an Hx-CTRIO2. The profile
is a homing routine similar to Home Search but has five additional features:
1. The profile is trapezoidal (has linear accel and decel rates), allowing for faster homing
routines without stalling the stepper.
2. The profile can be asymmetrical. (Accel and Decel rates are separate)
3. Encoder Feedback can be added, useful for correcting excessive lash or slippage in the
system.
4. Allows output rates up to 250kHz.
5. When Stop Trigger is position, it is a variable (parameter 3), set by the base controller.
NOTE: When using an input channel as the Stop Trigger with this profile, the Stop Trigger must be beyond
the first limit in the same direction. The output cannot change direction to reach the second limit. Use
Home Search if the output must Reverse to Limit 2.
The Trapezoid with Limits profile offers several routines using a Decel Trigger and Stop
Trigger. Specify the Decel Trigger as the rising or falling edge of a CTRIO2 input. The Stop
Trigger can be a position relative to the Decel Trigger, the opposite edge of the Decel Trigger
or the rising or falling edge of another CTRIO2 input.
NOTE: The Trapezoid with Limits profile requires that CRTIO2 inputs C and/or D are configured for Limit
Out X, where X is the output channel being used.
Decel Trigger: The CTRIO2 input to use as the Decel Trigger. Hitting this limit during the
move will either reset counts to 0 (if Stop Trigger is position) or initiate deceleration to the
Creep Frequency (if Stop Trigger is a CTRIO2 input).
Event: The edge of the limit switch to use as the Decel Trigger.
Counter I/O User Manual, 2nd Ed., Rev. D
Chapter 5: Configuring the CTRIO Outputs
Stop Trigger: The CTRIO2 input or position that stops the output. If Position is selected,
Parameter 3 defines the target position. This is relative to 0, which is clocked in when the
Decel Trigger’s Event condition is met. Position can be positive or negative.
Event: The edge of the limit switch to use as the Stop Trigger.
Minimum Freq: The frequency at which the profile will begin and end.
Maximum Freq: The maximum steady state frequency the profile can attain during a move.
Accel Rate: The rate at which the output frequency will increase at the start of the profile.
Decel Rate: The rate at which the output frequency will decrease when Decel Trigger is
reached.
Creep Freq: The (slower) rate to use between the Decel Trigger and the Stop Trigger.
Encoder Input: Select the channel where the encoder is connected.
Scale Factor: This is the output to input resolution (stepper/encoder) ratio. In other words, if
the stepper motor being used is a 1000 ppr (pulses per revolution) and the encoder is 800
ppr, then the scale factor would be 1000/800 = 1.25.
Deadband: This is the number of position counts away from the target position that causes
no action. This can reduce "hunting" or "ringing" as the profile attempts to get to the target
position. Be sure to include a deadband when the encoder has a higher resolution than the
stepper.
Example: Trapezoid with Limits using a limit switch for the Stop Trigger.

Additional Pulse Profiles
Three additional pulse profiles are available to use that are not
defined or created using the Pulse Profiles Table dialog, however
the output(s) must be configured for Pulse (Step/Direction) or
Pulse (CW/CCW) using the Configure I/O dialog. The profile
parameters are stored in the CPU/controller memory registers.
The profiles are briefly described below and will be discussed in
detail in Chapter 6. With all three profiles, the output is a step
response output to the specified target frequency, thus no
acceleration/deceleration parameters are configured.
Velocity Mode: User specifies the target frequency, pulse train
duty cycle and the step count. Once initiated, the output will
begin pulsing at the target frequency and continue until the step count is reached. With a step
count of 0xFFFFFFFF, the pulse output will continue indefinetly until the control program
disables the output.
Run to Limit Mode: User specifies target frequency and pulse train duty cycle. A CTRIO
module input (C or D) must be configured as a Limit input. When the Limit is reached the
pulse output is disabled.
Run to Position Mode: User specifies target frequency, pulse train duty cycle and target
position. The current position is obtained from the specified Input Function (i.e. Quadrature
counter). When the current position reaches the specified target position, the pulse output is
disabled. The comparing of the current and target position can be based on “greater than or
equal to” or “less than” values.
Hx-CTRIO2 with Do-more
In addition to the profiles in this manual, when an Hx-CTRIO2 is used with Do-more, Axis
Mode instructions are also available. With Axis Mode, it is not necessary to store profiles in
the CTRIO2. Instead, profile parameters are specified in a CTAXCFG (CTRIO2 Axis
Configuration) instruction. Then other Axis Mode instructions call for motion from the
module, which carries out their requests while adhering to the CTAXCFG parameters. Axis
Mode instructions also have stage control options for the complete or error events. Stage
programming tends to be well suited to motion applications, which are often sequential
processes.
Do-more CTRIO2 Axis Mode instructions:
CTRIO2 Axis Configuration (CTAXCFG)
CTRIO2 Axis Run Dynamic Position (CTAXDYNP)
CTRIO2 Axis Run Dynamic Velocity (CTAXDYNV)

Much of Chapter 6 of this manual does not apply to applications using Do-more as the
controller. The section, Pulse Output Profiles (functional descriptions of the various pulse
profiles), should be useful to Do-more users as these profiles are available on Do-more as
well. However, Do-more users using a CTRIO2 also have Axis Mode profiles available. Each
is controlled by a dedicated ladder instruction. Please see Do-more Designer help file for
more information on Axis Mode instructions for the CTRIO2.
One of the goals of the development of Do-more was to simplify use of modules such as the
CTRIO(2). When used with Do-more, Program Control is handled natively using memory
structures and dedicated ladder instructions. There is no CTRIO Memory Map to configure.
With Do-more, different CTRIO(2) registers are accessed through data structures, or using
the ladder instructions: CTRIO Read Register (CTREGRD) and CTRIO Write Register
(CTREGWR).
The data structures and other registers are automatically created when the module is added
and relevant features are selected in the CTRIO(2)’s configuration. The data structures have
names such as $CTRIO_000_C1F1.AtResetValue. The structure name is broken down as
follows:
$CTRIO_000_C1F1.AtResetValue
$ - corresponds to a system address
CTRIO - signifies that this structure pertains to a CTRIO module
000 - is the default designator for a CTRIO module in slot 0
Module Level
C1F1 - corresponds to input Channel 1, Function 1 (Out0 would
Structures
refer to Output 0)
.AtResetValue - is the structure member chosen, in this
particular case the value will go HIGH when the CTRIO
count has been reset to the configured reset value.
Using the DataView tool of Do-more Designer, a list of
possible structure members for a configured CTRIO module is
shown below.

I/O Map Dialog
The I/O Map dialog is accessible from the main Workbench dialog. On the main Workbench
dialog, click the button labeled I/O Map.
The I/O Map dialog divides the
controller I/O memory used by the
CTRIO module into three groups:
Input Functions, Output Functions
and System Functions.
Just below the Map Display Mode field, you will see tabs to switch between Input Functions,
Output Functions and System Functions.
Click on the Input Functions tab or Output Functions tab to display the CTRIO module’s
assigned input or output functions (quad counter, pulse catch, pulse out, discrete out, etc.).
For each input and/or output function assigned, the I/O Map dialog displays the Input Data
(CTRIO > Controller) addresses and Output Data (Controller > CTRIO) addresses based on
the Map Display Mode and the starting I/O addresses specified. The memory map addresses
displayed correspond to the offset addresses shown in the tables on the previous pages.
Click on the System Functions tab to display the System Functions addressing. The
command bits are used when reading from and writing to the CTRIO’s internal registers. The
other bits can be used to monitor the status of each individual I/O point on the module.
I/O Map with DirectLOGIC PLC (2 ranges mode)
When using the CTRIO module with a DirectLOGIC PLC, enter the starting V memory
location for the inputs and outputs in the appropriate fields at the top of the I/O Map dialog.
In the I/O Map dialog shown below, note that the Input, Output and Systems Functions
addresses shown are in word and bit-of-word formats. Thus, word and bit-of-word addressing
will need to be used in the ladder logic program to address the CTRIO’s control and status
words/bits.

I/O Map with DirectLOGIC PLC (4 ranges mode)
When using the CTRIO module with a DirectLOGIC PLC in 4 ranges mode, enter the
starting V-memory location for the word inputs and outputs and the starting V memory
location for the bit inputs and outputs. Control relays (V40600 range) would usually be used
for bit control.
In the I/O Map dialog below, note that Input, Output and Systems Functions addresses
shown are in word and Control Relay formats. Thus, word and Control Relay addressing will
need to be used in the ladder logic program to address the CTRIO control and status
words/bits. Remember that the CTRIO will consume the address ranges listed in all four
range fields.
NOTE: This mode exists specifically for using the CTRIO with the D2-240 CPU. If not using the D2-240
CPU, then use the 2 ranges mode mentioned on the previous page.

I/O Map with DirectLOGIC PLC with CTRIO in ERM/EBC Network
When using the CTRIO module with a DirectLOGIC PLC with the CTRIO module in an
ERM/EBC network, first configure the ERM network using the ERM Workbench utility.
Then, from ERM Workbench, enter the CTRIO’s starting input and output V-Map addresses
into the CTRIO Workbench’s I/O Map starting V memory location for the bit inputs and
outputs.
NOTE: If there is an 8-pt. discrete I/O module preceeding the CTRIO module in the EBC base, enter the the
appropriate starting V-memory bit I/O address in CTRIO Workbench with a V40xxx.8 address as shown in
I/O Map example below to the right. This corrects the word offset created by the 8-pt. discrete I/O module.
In the example below to the left, note that V40416 Hi(8-15) is the starting ERM Workbench CTRIO input
V-Map location due to the 8-pt. discrete input module preceeding the CTRIO module.
See Note
Above
I/O Map with EBC/WinPLC
When using the CTRIO module in an EBC/WinPLC system (non PLC system), the
addressing will be shown as Native EBC/WinPLC addresses or if using Think & Do, the
addressing can be shown as Native Think & Do
addresses. Just click on the desired mode in the
Map Display Mode field. The 8-pt module offset
described in the note above does not apply to
EBC/WinPLC or EBC/Think&Do systems.

I/O Map with an H2-PBC or T1H-PBC Profibus DP Controller
When using the CTRIO module with an H2-PBC or T1H-PBC native Profibus addressing
will be displayed in the I/O Map as shown below.
For the T1H-PBC, the first two output bytes of memory are automatically reserved for the
Hot Swap base-rescan feature. The H2-PBC does not support the Hot Swap feature.

H2-PBC I/O Map
Note that output bytes 0-1 are reserved
for the Hot Swap base rescan feature.
Creating an offline file for H2/T1H-CTRIO module
For the T1H-PBC, enter a 2 byte Output Offset to accommodate memory used by the Hot
Swap base-rescan feature. This does not apply to an H2-PBC system. The example shown
below assumes the T1H-CTRIO module is the first module in the system.
The CTRIO modules consume 44 bytes of input memory and 52 bytes of output memory.
The maximum amount of I/O memory per H2/T1H-PBC station is 244 input bytes and 242
output bytes. You may need to refer to the Profibus User Manuals (H2-PBC-M / T1H-PBCM) for information on bytes used by discrete and/or analog I/O modules to be able to
determine the appropriate Starting input and output byte offset addresses for the CTRIO
module.
For the T1H-PBC, enter a 2 byte Output
Offset to accomodate memory used by
the Hot Swap base-rescan feature.

Printing a Memory Map Report
You can print an I/O Memory Map Report from the I/O Map
dialog or save as a (.txt) file. Click on the Report button located
near the bottom of the I/O Map dialog to
display the Memory Map Report dialog.
The addresses listed in the Memory Map
Report are a combination of the Input
Functions, Output Functions and Systems
Functions addresses shown in the I/O Map
dialog. It is very convenient to have a
printed list of the CPU/controller I/O
memory used by the CTRIO module when
attempting to write the control program.
Exporting to DirectSOFT
You can export a (.csv) file containing addressing and nicknames used
in the I/O Map dialog. Click on the Export button located near the
bottom of the I/O Map dialog to display the Export to DirectSOFT dialog shown below on
the left.
The (.csv) file (shown below on right) contains a combination of the Input Functions,
Output Functions and Systems Functions addressing and nicknames shown in the I/O Map
dialog. This file can imported into your DirectSOFT ladder logic program
(DirectSOFT>File>Import>Element Documentation).
If you have more than one CTRIO module in a system and intend to create a (.csv) file for
more than one module, use the Add Prefix or Add Suffix option to distinguish one module’s
nicknames from the others. For example, add add prefix or suffix “S1” to identify the
CTRIO module’s nicknames in slot 1.

Addressing Conventions
1
(with V-memory Examples for DirectLOGIC PLCs)
2
Example for Bit-accessed Data in PLC CPUs
In this example, the V-memory location V2524 contains a value equal to 514 in decimal.
3
514 decimal = 0202 Hex = 0000 0010 0000 0010 binary
The bit V2524.1 refers to the 2nd to the least significant bit (set to 1 in this example).
4
Likewise, V2524.9 refers to bit number 9, the 10th from the least significant bit (also set to 1
in this example).

Addressing High and Low Byte of Word Parameters
In the following example, the V-memory location V2510 contains a value equal to 3 (decimal)
in the high byte and 10 (decimal) in the low byte.
9
3 decimal = 03 Hex = 0000 0011 binary in the high byte, and
10 decimal = 0A Hex = 0000 1010 binary in the low byte.
10
This example could represent the Command Code “Edit Table Entry.” The value 03 (Hex)
would represent the File number in the high byte, and the 0A (Hex) would represent the
11
remainder of the Command Code in the low byte.

Addressing High and Low Word of DWord Parameters
A
Double Word parameters are addressed in a similar fashion to the high and low bytes of a
Word Parameter. For example, a DWord that begins in V2300 consumes both V2300 and
V2301. The Low Word is V2300, and the High Word is V2301.

Standard Timers:
When the Enable Timer Capture bit is ON and the configured input edge occurs, the
CTRIO will begin timing. The Timer Capture Starting bit will be ON while the timing is in
progress and will turn OFF when the next configured input edge occurs and the Timer
Capture Complete bit turns ON. The program will need to turn off the Enable Timer

resets the timers register values to zero.
Free Run Timers:
If the Free Run Timer option was configured, the Enable Timer Capture bit is not available.
When the configured input edge occurs, the CTRIO will begin timing. The Timer Capture
Starting bit will be ON while the timing is in progress and will turn OFF when the next
configured input edge occurs. When this edge occurs, the Timer “in progress time” register
resets to zero. The “previous time” register will always retain the most recent captured time

Edge and Dual Edge Timer Timeout Function
The Timer Timeout Function is available for use with standard and Free Run Timers. It is
primarily used in Free Run timing of recurring events (rate, velocity calculations, etc.). The
specified Timeout Period is in effect once the timer is enabled until receiving the first
configured input edge. Then it is in effect until receiving the next edge of the timing input to
complete the timing cycle.
Standard Timers:
Once the timer is enabled, the Timeout Bit is set if the time that it takes the CTRIO to see
the configured input edge exceeds the specified Timeout Period. The program will need to
turn off the Enable Timer Capture bit, and confirm the Timer Capture Complete bit and
Timeout bit resets before attempting the next time capture cycle.
Once timing has been initiated, if the time before the CTRIO sees the next configured edge
exceeds the specified Timeout Period, the Timeout bit is set. The Timer register values are
reset to zero. The program will need to turn off the Enable Timer Capture bit, and confirm
the Timer Capture Starting bit, Timer Capture Complete bit and the Timeout bit reset before
attempting the next time capture cycle.
Free Run Timers:
The Timeout Bit is set if the time that it takes the CTRIO to see the configured input edge
exceeds the specified Timeout Period. The Timeout bit resets when the next timing cycle
begins. The “Previous Time” register value is reset to zero.
Once timing has been initiated, if the time before the CTRIO sees the next configured edge
exceeds the specified Timeout Period, the Timeout bit is set. The Timer register values are
reset to zero. The Timeout bit resets when the next timing cycle begins.

Pulse Catch Input Function
When the Enable Pulse Catch bit is ON and the configured input edge occurs, the CTRIO
will begin timing and the Pulse Catch Starting bit will turn ON. If the input signal remains
active for the specified qualification period, the Pulse Catch Output Pulse State bit will turn
ON for the configured duration. If a discrete output is assigned to follow the pulse state, it
will also turn ON for the configured duration. Unlike the Count or Time capture, the Pulse
Catch function is automatically reset as long as the Enable Pulse Catch bit remains ON.

Chapter 6: Program Control
1 Runtime Changes to CTRIO Configured Preset Tables (DL
PLCs)
2
Presets and preset tables can be set up entirely within CTRIO Workbench so that no program
control is necessary to assign discrete Preset Tables to CTRIO Input Fuctions.
3
You can make runtime edits to presets / preset tables from your control program. To make a
runtime change, a series of commands must be executed which will pass new values to a
preset table or call a different preconfigured table.
4
Command Codes are passed to the CTRIO module to effect the required edit. Each
Command Code has its own syntax, and all Command Codes must be presented in a
5
particular sequence:
The command code and associated parameters must be loaded into the appropriate memory
6
locations.
A Process Command instruction must be passed to the CTRIO module.
7
A Command Complete signal must be received and the Command Error bit must stay at zero.
Finally, the Enable Output instruction must be passed to the CTRIO module.
8
Some changes require a combination of Command Codes so those changes must follow the
steps above for each Command Code processed.

In order to process a command, first the program must load the Command and Required

1 and look for the CTRIO to acknowledge the command with the Command Complete bit.

Finally the program should remove the Process Command bit and set the Enable Output bit
when appropriate. If the Command Error bit is received, the CTRIO was unable to process
the command due to an illegal value in either the Command Code or Parameter fields.

Discrete Outputs Driven from a Scaled level
(Edit Level Response: Command Code 30)
If a Counter or Timer function is scaled to produce a rate, alarm level settings can be used to
trigger discrete outputs at values predetermined by the user. The alarm levels can be set within
CTRIO Workbench or from the user’s control program.
Additionally, a deadband percentage (in tenths of a percent) can be set to prevent the output
from changing too frequently near the Rate Level threshold.
“ON when greater” condition example:
Consider a Discrete Output set to turn ON when a level gets to 100 with a 10% deadband.
The output will turn ON when the level gets to 100. If the level drops, the output will stay
on until the level drops below 90, where it will turn OFF.
“OFF when less” condition example:
Consider a Discrete Output set to turn “OFF when less”at 100. When the level gets to 100,
the output turns OFF. If the level rises again, the output will stay OFF until the level gets to
110, where it will turn ON.
Edit the behavior of a Discrete Output triggered by a Rate Level by using the “Edit Level
Response Command” (Command Code 30Hex).
The Level Behavior setting for Parameter 1 is given in the table below:
Level Behavior for Discrete Output
Parameter 1 Contents
ON when greater than Level Rate setting
0000 Hex
ON when less than Level Rate setting
0080 Hex
OFF when greater than Level Rate setting
0001 Hex
OFF when less than Level Rate setting
0081 Hex
The Deadband is written to Parameter 2 as a x10 integer (one implied decimal position). To
achieve a 10.0% deadband, the control program needs to write 100 decimal (64 Hex) to
Parameter 2.
The Level Rate setting is written to Parameter 3 in the same format as Input Parameter 1 of
the CTRIO Function to which this Discrete Output has been assigned.

Profiles (DL PLCs)
1 Pulse Output
Loading a pre-defined Pulse Profile is the easiest method for pulse output motion control
(Command Code = 0010 Hex/BCD). For the Trapezoid, S-Curve, Symmetrical S-Curve,
2
Home Search and Free Form profiles, all of the required characteristics of acceleration, run
frequency, and total pulse count, etc. are entered in the CTRIO Workbench Pulse Profile
entry window. For Dynamic Positioning, Dynamic Positioning Plus, Trapezoid Plus,
3
Trapezoid with Limits and Dynamic Velocity profiles, the target position and target velocity
are stored in a memory location in the controller. All other profile characteristics are entered
4
in the CTRIO Workbench Pulse Profile entry window.
For Velocity Mode (Command Code = 0020 Hex/BCD), Run to Limit Mode (Command
5
Code = 21 Hex/BCD) and Run to Position Mode (Command Code = 22 Hex/BCD) all
profile parameters are stored in the controller’s memory registers. No CTRIO Workbench
Pulse Profile is required.
6
In order to process a command, first the program must load the Command Code and
required DWord, Word, and bit parameters. Then the program should drive the Process
7
Command bit to a 1 and look for the CTRIO to acknowledge the command with the
Command Complete bit. Finally, the program should remove the Process Command bit and
8
set the Enable Output bit when appropriate. If the Command Error bit is received, the
CTRIO was unable to process the command due to an illegal value in either the Command
Code or parameter files.
9
On the pages that follow, Pulse Profile and System Functions flowcharts are provided to give
an overview of the steps needed to execute a pulse output profile or a SystemFunctions

Chapter 6: Program Control
Trapezoid, S-Curve, Symmetrical S-Curve, Home Search, Free Form Profiles
For predefined Trapezoid, S-Curve, Symmetrical S-Curve, Home Search and Free Form
profiles, the program needs to prepare the Load Table command by selecting Command
Code = 0010 Hex/BCD and setting Word Parameter 1 to the File number of the profile
(example: File 1 Trapezoid 1). Then the program can set the Process Command bit and watch
for the Command Complete bit. Then the program should clear the Process Command bit
and set the Direction bit (if necessary) and finally the Enable Output bit to start the output
pulses. Clearing the Enable Output bit will always suspend pulsing and reset any profile in
progress to it’s beginning . Once complete, the profile remains loaded and can be restarted by
clearing the Enable Output, changing the direction bit (if desired), and again setting the
Enable Output. The flowchart on the next page provides the logical sequence necessary to
execute a Trapezoidal, S-Curve, Symmetrical S-Curve, Home Search or Free Form pulse
profile.
For the Home Search routine, a CTRIO input must be assigned to Limit by the CTRIO
Workbench Configure I/O dialog.
See Chapter 8 for a DirectLOGIC programming example that loads and runs a pulse profile
using the bit/(D)word addressing in the table on the page 6-34.
NOTE: For a Home Search Profile: if you are at the home position and the Home Search profile is initiated,
there will not be any pulse outputs.

Dynamic Positioning and Dynamic Positioning Plus
For Dynamic Positioning/Positioning Plus, only the motion limits of Min Frequency, Max
Frequency, and Acceleration rate come from the CTRIO Workbench Profile. After loading a
Dynamic Positioning/Positioning Plus Profile, setting the Enable Output causes the CTRIO
module to assume a position of 0 pulses. The program should write the next target position in
DWord Parameter 3, and set the Go to Position bit. This will cause the CTRIO to set both
the Pulses Active and the New Position Loaded bit and begin to output pulses. The number
of pulses and direction are determined by the CTRIO based on the difference between the
current location and the specified target location. The flowchart on the following page
provides the logical sequence necessary to execute this type of pulse profile.
The program can monitor the state of the Pulses Active bit and the New Position Loaded bit
to determine when the new position has been attained. The New Position Loaded status bit
will always follow the state of the Load/Seek New Position control bit. This status bit should
be used to signal the program that the CTRIO has received the new state of the control bit.

CTRIO Pulse Output State
You do not have to wait on the CTRIO to complete a move that is in progress before loading
the next target location. After the GoTo Position is acknowledged, the program can load the
next position into the DWord Parameter 3. When Pulses Active Status goes to 0, then setting
the GoTo Position control bit will again start the output toward the new position. The
CTRIO moves to the new position relative to its previous position as long as the Enable
Output control bit remains set. Clearing the Enable Output bit will disable output pulsing
and reset the current position to 0.
See Chapter 8 for a DirectLOGIC programming example that executes a Dynamic
Positioning/Positioning Plus pulse profile using the bit/(D)word addressing in the table on
page 6-37.
The sign of the value in the Target Position
register (Parameter 3) determines the
direction of the pulse train output. In the 1
DirectLOGIC programming example to

Chapter 6: Program Control
Dynamic Velocity
For Dynamic Velocity, the motion limits of clockwise acceleration and deceleration, and
counter clockwise acceleration and deceleration come from the CTRIO Workbench Profile.
The target velocity is stored in a register in the CPU/controller.
The program needs to prepare the Load Table command by selecting Command Code =
0010 Hex/BCD, set Word Parameter 1 to the File number of the profile (example: File 3
Dynamic Velocity 1) and set Word Parameter 3 to the desired target velocity. Then the
program can set the Process Command bit and watch for the Command Complete bit. Then
the program should clear the Process Command bit. Set the Enable Output bit to start the
output pulses. The velocity can be changed “on the fly” by entering a different value into the
target velocity register. The velocity will ramp up/down to the new target velocity at the
specified accel/decel rates. Clearing the Enable Output bit will always suspend pulsing.
See Chapter 8 for a DirectLOGIC programming example that executes a Dynamic Velocity
pulse profile using the bit/(D)word addressing in the table below.

Velocity Mode
NOTE: Velocity Mode controls the pulse outputs directly from the CPU/controller program. No CTRIO
Workbench Pulse Profile is required for this mode.
Velocity Mode command (Command = 0020 Hex/BCD) allows a specified number of pulse
output counts or the number of Pulses can be set to “FFFFFFFF” in Hex for unlimited pulse
counts. Leaving the Duty Cycle set to 0 achieves the default (50%), otherwise it can be set in
1% increments by writing this value from 1 to 99 decimal. After this command is processed,
the Run Frequency and Duty Cycle fields can be adjusted by direct access. In order to change
directions from Pulse Output in “Velocity” mode, the Enable Output bit must first be cleared
(which stops the Pulse Outputs). Then after the new direction bit is written, the Enable
Output bit can be set to resume pulsing. The flowchart on the following page provides the
logical sequence necessary to execute a Velocity Mode pulse profile.
See Chapter 8 for a DirectLOGIC programming example that executes a Velocity Mode
pulse profile using the bit/(D)word addressing in the table below.

Run to Limit Mode
NOTE: Run to Limit Mode controls the pulse outputs directly from the CPU/controller program. No CTRIO
Workbench Pulse Profile is required for this mode.
The Run to Limit (Command = 0021Hex/BCD) can be used to seek limit positions or for
Home Search routines. You may want to consider using the Trapezoid with Limits Profile or
the Home Search Pulse Profile created using Workbench unless you need the CPU/controller
to control the entire profile and parameters, etc. The CTRIO input must be assigned for
Limit by the CTRIO Workbench utility.
Set Word Parameter 1 to the desired Frequency. Set Word Parameter 2 Low Byte to the Duty
Cycle and the High Byte to the Edge to Seek as defined below. Leaving the Duty Cycle set to
0 achieves the default (50%), otherwise it can be set in 1% increments by writing this value
from 1 to 99 Hex/BCD.
The flowchart on the following page provides the logical sequence necessary to execute a Run
to Limit pulse profile.
See Chapter 8 for a DirectLOGIC programming example that executes a Run to Limit Mode
pulse profile using the bit/(D)word addressing in the table on page 6-44.
Parameter 2
Word Parameter 2 defines three elements of the Run to Limit routine. Bits 13 and 12
determine which edge(s) to terminate Output Pulses and Bits 9 and 8 determine which
CTRIO Input terminal to use for the limit. The low byte specifies the duty cycle.

NOTE: Run to Position Mode controls the pulse outputs directly from the CPU/controller program. No
CTRIO Workbench Pulse Profile is required for this mode.
The Run to Position Mode command (Command = 0022Hex/BCD) allows Pulse Outputs
that terminate when the specified Input Function Value position count is reached. Set Word
Parameter 1 to the desired Frequency. Set Word Parameter 2 Low Byte to the Duty Cycle and
the High Byte to the Compare Functions as defined below. Leaving the Duty Cycle set to 0
achieves the default (50%), otherwise it can be set in 1% increments by writing this value
from 1 to 99 Hex/BCD.
Word Parameter 3 specifies the value that Input Function will compare against.
The flowchart on the following page provides the logical sequence necessary to execute a Run
to Position pulse profile.
See Chapter 8 for a DirectLOGIC programming example that executes a Run to Position
pulse profile using the bit/(D)word addressing in the table on page 6-47.
Parameter 2
Word Parameter 2 defines three elements of the Run to Position routine. Bit 12 determines if
the specified position is “greater than or equal” or “less than” the current Input Function

System Functions
System Functions Commands are primarily used to read from and write to the CTRIO’s
internal registers. The flowcharts on the following pages provide DirectLOGIC and
ThinknDo users the logical sequence necessary to read from and write to the CTRIO’s
internal registers.
The CTRIO’s internal current count register can be read from or written to to if the input is
configured for a Counter or Quadrature Counter. Timer values are not accessable.
The CTRIO’s internal current output pulse count can be read from or written to only if the
pulse output is running Dynamic Velocity or Dynamic Positioning profiles.
See Chapter 8 for DirectLOGIC programming examples that use the RD and WT
instructions to execute system function commands.
See Chapter 9 for Do-more programming examples using read and write instructions to
execute system function commands.

Do-more and Monitor CTRIO
In Do-more, Monitor CTRIO is part of the Do-more Designer programming software. To
1
access Monitor CTRIO in Do-more Designer, look under the PLC menu and select Monitor
CTRIO Module. For detailed information on using Monitor CTRIO Module in Do-more
Designer, see help file topic DMD0308: Monitor CTRIO Module. You can also access this
2
help file topic by opening Monitor CTRIO and pressing F1.
3
Using the Monitor I/O Dialog
4
NOTE: It is highly recommended to simulate your CTRIO Counter, Timer or Pulse Output Profile, etc.
application using Monitor I/O before attempting to control the module from your controller program.
5
Monitor I/O is extremely useful for debugging and the commissioning of a new system. Monitor I/O allows
you to confirm proper configuration of the module, as well as field wiring and external device operation.
6
The Monitor I/O dialog is accessible from the main Workbench
dialog when the module is in Run Mode.
7
On the main Workbench dialog, click the button labeled
Monitor I/O.
8
After clicking on the Monitor I/O button, the dialog below will appear if you have mapped
the I/O in the CTRIO to the controller. Here you have the ability to suspend CTRIO reads
9
from the CPU/controller. Doing so will allow Monitor I/O to control the CTRIO without
any control program intervention. With the output reads suspended, the Monitor I/O dialog
allows you to simulate program control; for example, enabling a timer, resetting a counter,
10
running a pulse profile or turning on an output configured for Raw mode, etc. When exiting
Monitor I/O, you will be prompted to re-enable the controller output reads.

I/O Status & Input Functions
I/O Status & Input Functions dialog includes all Input Function DWord Parameters (raw
count/time, scaled count/time, etc.) and status bits passed from the CTRIO module to the
CPU (Capture Starting, Complete bits, etc.). The control bits that would be passed from the
CPU to the CTRIO are also included (Function enable bits, etc.).
The current status of each configured input and output is shown just below the Input Status
and Output Status columns.
In the example above, the Current Count for Ch1/Fn1 Quad counter is 994. The Reset
Count button can be used to reset the count to the configured Reset Value.
For Ch1/Fn2, the Edge Timer is captured at 38us. The Enable Capture bit must be on prior
to when the configured edge input occurs.
Note that Output Status Out 0 and Out 3 are ON. Out 0 is configured for pulse output and
Out 3 is configured for a Raw discrete output. These outputs can be controlled from the
Output Functions window.

Output Functions
The Output Functions dialog includes all Output Function Word and DWord Parameters
(file number, duty cycle, target position, etc.) and status bits passed from the CTRIO module
to the CPU (Output Enabled, Command Complete, etc.). The control bits that would be
passed from the CPU to the CTRIO are also included (Enable Output, Go to Position,
Direction, etc).
In the example above, Outputs 0 and 1 are configured for Pulse step and direction, Output 2
is configured to Preset mode assigned to Ch1/Fn1 (quad counter) and Output 3 is configured
as Raw mode.
In the screen capture on the left, notice the pull down menu. The menus are context
sensitive. They will change to display values that are appropriate to the CTRIO’s
configuration. Here you have acccess to all pulse profile commands. Command 0x10 will
allow you to load any configured Pulse Profiles (Trapezoidal, S-Curve, Dynamic Positioning,
etc.). In the screen capture on the right, you’ll see we have selected Pulse Profile number 2 for
this example.
To run a configured Pulse Profile, follow these steps:
1) select Command Code 10 (0x10)
2) enter the desired Pulse Profile Number in the File Number field
3) click the Process Command button and confirm the Command Complete bit is ON. If
the Command Error is ON, an explanation of the error will appear on the dialog status line.
Then turn the Process Command button OFF.
4) select the Direction; leaving the Direction button OFF selects forward, clicking the button
ON selects the reverse direction.
5) click on Enable Output to run the Pulse Profile. The Output Enabled and Output Active
indicators will turn ON. When the profile is complete, the Output Active indicator will turn OFF.
Turning OFF the Enable Output during the profile run will terminate the pulse output. To
run the profile again, turn OFF the Enable Output and then re-enable it.
Counter I/O User Manual, 2nd Ed., Rev. D
Chapter 7: Using Monitor I/O
In the screen capture on the right on the previous page, notice the drop down menu. Here
you have access to all of the Preset Table Commands. The Load Table Command (0x10) will
allow you to load any configured Preset Tables. In the screen capture on the left, you’ll see we
have selected Preset Table number 1 for this example. Remember that Output 2 is assigned to
Input Function Ch1/Fn1, which is configured as a Quad Counter Input.
To load a configured Preset Table for Output 2 to use based on Ch1/Fn1’s count, follow the
steps below:
1) select Command Code 10 (0x10)
2) enter the desired Preset Table Number in the File Number field
3) click the Process Command button and confirm the Command Complete bit is ON. If the
Command Error is ON, an explanation of the error will appear on the dialog status line.
Then turn the Process Command button OFF.
4) click on the Enable Output to allow the output to operate based on the Preset Table and
current status of Ch1/Fn1 quad counter input.
As the encoder’s count on Ch1/Fn1 changes, the output 2 turns ON and OFF based on the
entries in Preset Table number 1. Turning the Enable Output OFF while the Preset Table is
being executed will disable the output.
Pulse Output Command Codes 0x20, 0x21 and 0x22
Velocity mode (0x20) is shown in the example above. Depending upon which command is
selected, different parameter fields, status bits and control bits will apply. No matter which
one is selected, be sure to fill in the parameter fields with valid entries (refer to chapter6), and
then Process the Command.

System Functions
The Systems Functions dialog allows you read from or write to the current input count and
the current output pulse count under the following conditions:
• The current input count can be read from or written to if the input is configured for a Counter or
Quad Counter. Timer values are not accessable.
• The current output pulse count can be read from or written to only if the pulse output is running
Dynamic Velocity or Dynamic Positioning profiles.
DirectLogic Users
The reading from and writing to the CTRIO internal registers is accomplished using the
DirectLOGIC Read from Intelligent module (RD) and Write to Intelligent module (WT)
instructions, respectively. See chapter 8 for Systems Functions ladder logic examples.
EBC, WinPLC, PBC, DEVNETS, MODBUS Users
The Systems Functions dialog is available for use when connected to these interface devices,
however, there is currently no way for the user control program to read from or write to the

NOTE: The programming examples on the following pages are provided “as is” without a guarantee of any
kind. This Chapter is provided by our technical support group to assist others. We do not guarantee the
examples are suitable for a particular application, nor do we assume any responsibility for them in your
application. Chapter 6 “Program Control” contains flowcharts that provide detailed steps needed to execute
a pulse profile or System Functions command.
The DirectSOFT programming examples provided on the following pages are simple
examples that are intended to assist you in the basics of loading and running various output
pulse profiles. The examples are complete enough to load a profile, process the command and
load the Parameter registers necessary to execute the profile. Two System Functions examples
are also provided.
Load and Run a Pulse Profile example:
You will need to have a Trapezoid, S-Curve, Symmetrical S-Curve, Home Search or Free
Form profile configured using the Configure I/O dialog. You will also need to have the
appropriate Pulse Profile Table File Number (decimal) stored in V3000 for this example. You
must turn C0 on to load and run the pulse profile. C2 controls the pulse output direction.
Dynamic Positioning/Positioning Plus Profile example:
You will need to have a Dynamic Positioning/Positioning Plus profile configured as Table File
Number 1 using the Configure I/O dialog. You will also need to have the appropriate Target
Pulse Count Position (signed decimal) stored in V3000 for this example. You must turn C0
on to initialize the settings. Then turn C2 on to Go to Position.
Dynamic Velocity Profile example:
You will need to have a Dynamic Velocity profile configured as Table File Number 1 using the
Configure I/O dialog. You will also need to have the appropriate Target Velocity (signed
decimal) stored in V3000 for this example. You must turn C0 on to initialize the settings and
enable the output.
Velocity Mode, Run to Limit Mode and Run to Position Mode examples:
No CTRIO Pulse Profile Tables are necessary to execute these profiles, but the Outputs need
to be configured for Step/Direction or CW/CCW using the Configure I/O dialog. All
parameters are stored in memory as shown in the examples. You must turn C0 on to initialize
the settings and to run the pulse profile. C2 controls the pulse output direction. For Run to
Position Mode, Ch1 Inputs A & B must be configured for Quad Counter in CTRIO
Workbench. The position from that encoder is used to stop the move.
Simulating Retentive Counter example:
This Systems Functions example uses the Write to Intelligent (WT) instruction to write the
current count stored in the PLC’s retentive memory to the CTRIO’s current count register on a
power cycle or a RUN-STOP-RUN PLC mode change. No permissive bits are required to be
turned on in this example.
Reading CTRIO Internal Registers example:
This Systems Functions example uses the Write to Intelligent Module (WT) and Read from
Intelligent Module (RD) instructions to read all of the CTRIO’s internal registers every 900ms. You
must turn C0 on to initialize the settings to perform the Read routine.

Load and Run a Pulse Profile
The following example program loads and executes a Pulse Profile that was created using
CTRIO Workbench Pulse Profiles dialog . This example can be used for Trapezoid, S-Curve,
Symmetrical S-Curve, Home Search and Free Form profiles (Home Search requires that
CTRIO inputs C and/or D are configured for Limit Out 0 and/or Limit Out 2). The Pulse
Profile number is stored in V3000 for this example. Turning on C0 will load and run the

The following example program runs a Dynamic Positioning/Positioning Plus pulse profile.
Turn on C0 to load the profile number and process the command. The first move starts at
position count = 0. Turning on C2 will start the pulse output to position specified in Parameter
3.
The output will move in whichever direction is appropriate to reach the position specified in
Parameter 3. To make additional moves, wait for the current move to complete, load a new
value into the Target Pulse Count register and set the Go to Position bit. Subsequent moves are
still referenced to the same 0 location as the first move. Clearing the Enable Output bit will
disable output pulsing and reset the current position to 0.

System Functions Examples Overview
8–10
NOTE: System Functions are supported only when the CTRIO module is installed in the same base as the
DirecttLOGIC CPU.
The Systems Functions examples on the following pages use the DirectLOGIC Write to
Intelligent Module (WT) and/or Read from Intelligent Module (RD) instructions to write to
or read from the CTRIO’s internal registers.
Reading From CTRIO Internal Memory
Reading the CTRIO’s internal memory consists of several steps. Step one is using the WT
instruction to send a Systems Function’s command to the CTRIO telling it to put its internal
register values into the CTRIO’s “shared RAM”. Step two is processing the request for the
internal register values using the Process Command bit. Step three is using the RD
instruction to read the values from the CTRIO’s “shared RAM” memory into PLC
V-memory.
Steps 1 and 2: WT instruction and Process Command
PLC V-memory ==> CTRIO’s Shared RAM
CTRIO’s Shared RAM ==> Process Command to internal processor
CTRIO’s Shared RAM <== Internal data values
Step3: RD instruction
PLC V-memory <== CTRIO’s Shared RAM
Writing to CTRIO Internal Memory
Writing to the CTRIO’s internal registers is basically a two step process. Step one is using the
WT instruction to send a System Function’s command and the desired data values to the
CTRIO’s “Shared RAM”. Step two is using the Process Command bit to tell the CTRIO to
process the command and data values that are in the CTRIO’s Shared RAM. This moves the
data values from the Shared RAM into the CTRIO’s internal registers.
Steps 1 and 2: WT instruction (command and data) and Process Command Bit:
PLC V-memory ==> CTRIO Shared RAM
CTRIO Shared RAM ==> Process Command to internal processor
CTRIO Shared RAM ==> internal data registers
NOTE: This function is not available when the CTRIO module is installed in a EBC expansion base.

Do-more Programming Examples Overview

NOTE: The programming examples on the following pages are provided “as is” without a guarantee of any
kind. This Chapter is provided by our technical support group to assist others. We do not guarantee the
examples are suitable for a particular application, nor do we assume any responsibility for them in your
application.
The Do-more Designer programming examples provided on the following pages are simple
examples that are intended to assist you in the basics of loading and running various output
pulse profiles. The examples are complete enough to load a profile, process the command and
load the Parameter registers necessary to execute the profile. Two System Functions examples
are also provided.
Load and Run a Pulse Profile example:
You will need to have a Trapezoid, S-Curve, Symmetrical S-Curve, Home Search or Free
Form profile configured using the Configure I/O dialog.
Dynamic Positioning/Positioning Plus Profile example:
You will need to have a Dynamic Positioning/Positioning Plus profile configured as Table File
Number 1 using the Configure I/O dialog.
Dynamic Velocity Profile example:
You will need to have a Dynamic Velocity profile configured as Table File Number 1 using the
Configure I/O dialog.
Velocity Mode, Run to Limit Mode and Run to Position Mode examples:
No CTRIO Pulse Profile Tables are necessary to execute these profiles, but the Outputs need
to be configured for Step/Direction or CW/CCW using the Configure I/O dialog. All
parameters are stored in memory as shown in the examples. For Run to Position Mode, Ch1
Inputs A & B must be configured for Quad Counter in the Configure I/O dialog. The
position from that encoder is used to stop the move.
Simulating Retentive Counter example:
This Systems Functions example uses the Write to Intelligent (WT) instruction to write the
current count stored in the PLC’s retentive memory to the CTRIO’s current count register on a
power cycle or a RUN-STOP-RUN PLC mode change. No permissive bits are required to be
turned on in this example.
Reading CTRIO Internal Registers example:
This Systems Functions example uses the Write to Intelligent Module (WT) and Read from
Intelligent Module (RD) instructions to read all of the CTRIO’s internal registers every 900ms. You
must turn C0 on to initialize the settings to perform the Read routine.

Rung 1 copies the CTRIO’s counts value from channel 2 into a retentive memory location on
every scan, except the First Scan.
NOTE: This example uses the .iReg1 member, which contains integer raw counts when no scaling is
applied in the CTRIO module configuration. If scaling WERE applied for this CTRIO function, .iReg1 would
contain the scaled value and .iReg2 would contain the raw counts. CTREGWR only writes to the raw counts
accumulator, so use .iReg2 if this CTRIO function is scaled in your configuration.
Rung 2 uses the CTREGWR instruction to write the retained value back into the CTRIO’s
internal register on the First Scan.
NOTE: Since CTREGWR is an asynchronous instruction (note the red triangle), execution of any other
ladder that references the current count of this CTRIO needs to be held off until this CTREGWR instruction
returns its On Success bit, or its On Success JMP to Stage.
For detailed information on the CTREGWR – CTRIO Write Register instruction, see Domore Designer help file topic DMD0527.

Reading CTRIO Internal Registers
9–10
For most applications, reading CTRIO Internal Registers using ladder is not necessary. All the
data needed from the module is already made available in the Do-more CPU through the
CTRIO module structure. For a list of CTRIO module structures, see Help File topic:
DMD0313 High Speed I/O Applications.
There are some registers in the CTRIO whose values are not available in structures. Examples
are the Reset Value for a resettable counter and Filter Time for inputs. To read these values
into ladder, use the CTREGRD - CTRIO Read Register instruction as shown below.
NOTE:: The CTREGRD instruction can also be used to read the accumulator for a counter channel.
However, this value is already available in structure elements .iReg1, .iReg2, .fReg1, or .fReg2. The only
time CTREGRD would need to be used to read the accumulator is if scaling and capture are enabled and
the raw accumulator value is needed in ladder.
In the sample ladder above, turn on C7 to read in the Channel1 Function1 Reset Value of the
CTRIO module in slot 0. The value will be written into address nicknamed
Ctr0C1F1RstVal.
For detailed information on the CTREGRD – CTRIO Read Register instruction, see Domore Designer help file topic DMD0526.
