Introduction
General Information about the CTRIO Module
The Counter I/O (CTRIO) module is designed
to accept high-speed pulse-type input signals
and provide discrete or pulse outputs for
monitoring, alarm, or control functions. The
CTRIO module offers great flexibility for
applications which call for precise counting
or timing, based on input events.
The CTRIO module has its own
microprocessor and operates asynchronously
with respect to the CPU. The response time of
on-board outputs is based on the module’s
scan time, not the CPU’s scan time.

CTRIO Workbench
All scaling and configuration is done
via a software utility, eliminating the
need for ladder programming to set up
the module. The software utility is
called CTRIO Workbench. The use of
CTRIO Workbench is explained in
Chapter 3.
Supported CPUs
You can use the CTRIO module with
conventional CPUs (D2-240 or D2-250),
our Windows-based WinPLC CPU
module, or PC-based control strategies
using the H2-EBC interface module.
The CTRIO module plugs into any I/O slot of any DirectLogic 205 base except slot 0 (slot
0 is available for the CTRIO module when using the WinPLC CPU). Slot 0 is the I/O slot
adjacent to the CPU. Multiple CTRIO modules can reside in the same base provided that
the power supply is adequate. CTRIO modules may be placed in secondary local bases
connected via ERM-to-EBC.
The CTRIO module is designed to work with incremental encoders or other field devices
that generate pulses or edges.
Typical Counter Applications:
• cut to length
• piece counting
• positioning (e.g. flying punch)
• PLS - programmable limit switch replacement (e.g. gluing application)
• stepper motor drive control
• valve control
• rate monitoring for speed and/or flow

How to Install the CTRIO Module
The CTRIO module installs into any DL205 base, and it is compatible with several
DL205 CPU-slot devices. Consideration must be given to the firmware versions of the
CPU-slot devices to assure their compatibility (see chart below).
DirectSOFT32 version 3.0C, Build 71 (or later) is required for use with the CTRIO
module if the D2-240 or D2-250 CPUs are to be used.
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 CTRIO Module
The CTRIO module is a two channel device. Each channel accepts four optically isolated
input signals which share the same common. Input circuits can be wired with either
polarity without changing the module configuration. Channel 1 inputs can have the
opposite polarity from channel 2 inputs.
The module is configured, using CTRIO Workbench, to
accommodate the user’s application. The function of each
input is defined in the configuration of the module
(counting, timing, reset, etc.). Refer to Chapter 3, to
determine what input configurations are possible.
Field device wiring must be
compatible with the module
configuration.

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 userprovided 5-36VDC power sources. The maximum allowable current per
output circuit is 1A.

Chapter 3: Configuring the CTRIO with Workbench
What is CTRIO Workbench?
CTRIO Workbench is the software utility you will use to configure the CTRIO module
and to scale signals to desired engineering units. Workbench also allows you to perform
various other functions, such as switching between the CTRIO’s Program mode and Run
mode, monitoring I/O status and functions, and diagnostic control of module functions.
The CTRIO Workbench utility ships with the CTRIO User Manual. You can also
download the latest version free at the Host Engineering Web site: www.hosteng.com.
Installing CTRIO Workbench
The CTRIO Workbench utility installs directly from its executable file. Double click on
the SetupCTR.exe icon. The install shield will step you through the installation process.
Two versions of CTRIO Workbench are loaded on your PC during the installation. One is
for DirectSOFT32 users. It runs from within DirectSOFT32. CTRIO Workbench requires
DirectSoft32, Rel. 3.0C, Build 71 (or later).
The other version is for H2-WPLC and H2-EBC users, and it may or may not run from
within the control software furnished with the WinPLC module. For further information,
see your WinPLC’s software documentation.
Getting Started with CTRIO Workbench
To run CTRIO Workbench, an H2-CTRIO module must be
installed in the base, and the base must be powered up.
You will need to connect to a port on the DirectLOGIC
CPU, D2-DCM, H2-ECOM, H2-EBC, or H2-WPLC. Your PC
communicates with the CTRIO module through the CPUslot device port or through a port on a DCM or ECOM
module.
Several paths are available to start CTRIO Workbench.
DirectSOFT32 users will find CTRIO Workbench under
PLC (menu)/Tools/CTRIO Workbench.
DirectSOFT32 users will also find
access to CTRIO Workbench in the
DirectSOFT32 Launch Window. Double
click the Workbench icon as you would
do to open a project.
All users will find CTRIO Workbench at
Start/Programs/AutomationDirect
Tools/CTRIO Workbench.

Chapter 3: Configuring the CTRIO with Workbench
Linking to CTRIO Module in DirectSOFT32
If you are linked to your CPU through
DirectSOFT32, 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.
Successful Connection
Once you are connected to your PLC (or
PLC network) and you select the desired
CPU (Link), 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. If the steps mentioned above are all accomplished
successfully, you will be able to enter Workbench’s configuration and monitoring
dialogs, and you will be able to toggle the CTRIO module between Program Mode and
Run Mode.
Counter I/O User Manual
3–3
Chapter 3: Configuring the CTRIO with Workbench
Choose “Program Mode” to Configure the CTRIO Module
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 configure the
module “offline” 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.
Clicking on the Config I/O button, causes
the Configure I/O window to appear. From the Configure I/O
window, you can select the primary input functions your
application requires and assign those functions to
appropriate terminals.
You can also select subordinate functions on the Configure
IO dialog. Primary and subordinate functions are explained
in more detail under the heading “Supported Functions.”
After the configuration is created 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.”
Entering program mode takes the CTRIO module offline. Input pulses are not read or
processed in Program mode, and all outputs are disabled. DirectLOGIC CPUs will hold
last value in V-memory while the CTRIO is in Program Mode.
Choose “Run Mode” to Start Processing Pulses with the CTRIO
Selecting Run Mode causes the CTRIO module to begin processing pulses based on the
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. The
Monitor feature is particularly useful during debugging and commissioning of a new
system. This feature allows you to verify that wiring and configuration were performed
correctly.
If you are using a DirectLOGIC CPU, 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.
The CTRIO module will not enter Run Mode if it does not have a valid configuration
stored.

Chapter 3: Configuring the CTRIO with Workbench
Using the Configure IO Dialog
The Configure IO 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 function boxes prompt you with selections for supported functions. The
Workbench software disallows any unsupported configurations.
From the main CTRIO Workbench window, click on the “Go to PROGRAM Mode” button.
Then, click on the “Config I/O”
button to arrive at the dialog below.
Notice that the window has a tab for
each Channel. Channel 1 and
Channel 2 offer the same
configuration options.
A maximum of one quadrature input
or two single-ended encoder inputs
is possible for each 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.
Select the desired input function by
clicking on the input type and then
clicking OK.
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.
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.”
Field devices and field wiring must be consistent with the configuration chosen.
The Output functions are listed as 0, 1, 2, and 3. These numbers correspond to the
markings beside the module’s output terminals. Again, only supported functions are
accessible. It is not possible to create an “illegal” configuration.
Counter I/O User Manual

Chapter 3: Configuring the CTRIO with Workbench
Supported Functions
Reset, Inhibit, and Capture. If desired, two subordinate functions can be selected for the
first Counter on each channel, Reset and Inhibit or Reset and Capture.
Capture and Inhibit use the same terminal, so you cannot use both of those subordinate
functions. You can also access the Scaling Wizard, for counting and timing applications
and other configuration features.
The CTRIO module supports five primary input functions: Counter, Quad Counter, Pulse
Catch, Edge Timer, and Dual Edge Timer. Each of the primary functions uses one or two
terminals for making connections to field devices (plus a common).
Three secondary input functions are also supported. These functions, Reset, Capture,
and Inhibit, each modify the primary input functions in some way. More information is
available about each of the primary and secondary functions later in this chapter.

Input Function Selections
To make function selections (counter, timer, etc.), navigate to
the Configuration IO dialog. From the main Workbench
window, click the “Config IO” button to open the Config IO
dialog.
Counter Function
The CTRIO module supports up or down counting using single-ended encoders (or other
single-ended pulse sources) as inputs. Encoders, proximity 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 more fully explained later
in this chapter.
To insure proper operation, the field
device wiring and the configuration
must be compatible. For wiring
information see Chapter 2.
A
To select the Counter function, first
open CTRIO Workbench. On the main
dialog, click the button labeled “Config
IO.” This causes the Input Settings
dialog to open.
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.

encoders as inputs. Connect your
encoder to input A and input B on
either channel. A second quadrature
endcoder 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 more fully
explained later in this chapter.

To select the Quad Counter function,
first open CTRIO Workbench. On the
main dialog, click the button labeled
“Config I/O.” This causes the Configure
IO dialog to open.
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 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.

Chapter 3: Configuring the CTRIO with Workbench
Pulse Catch
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 can also be tied to the
Pulse Out.
To insure proper operation, the field
device wiring and the configuration
must be compatible. For wiring
information see Chapter 2.
To select the Pulse Catch function, first
open CTRIO Workbench. On the main
dialog, click the button labeled “Config
I/O.” This causes the Input Settings
dialog to open.
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
n + 20.8
state, you will want to trigger off
status bit
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.
D
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.

Edge Timer
The Edge Timer measures the time
from the rising edge of one pulse to
the rising edge of the next pulse, or the
falling edge of one pulse to the falling
edge of the same pulse, or the falling
edge of one pulse to the falling edge of
the next pulse. Encoders, proximity
sensors, etc., can be connected to
input C and/or input D on either
channel or both channels.
A
To insure proper operation, the field
device wiring and the configuration
must be compatible. For wiring
information see Chapter 2.
To select the Edge Timer function, first
open CTRIO Workbench. On the main dialog, click the button labeled “Config I/O.” This
causes the Input Settings dialog to open.
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 Counter in box C.
At this point, you have three decisions
to make regarding your input at 1A.
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.

To select the Dual Edge Timer function, first open CTRIO Workbench. On the main
dialog, click the button labeled “Config I/O.” This causes the Input Settings dialog to
open.
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
inputs to terminals 1C and 1D, you will need to
select the Channel 1 tab near the top of this
window and click Dual Edge Timer in box C or D.

At this point, you have three
decisions to make regarding your
input at 1C or 1D.
1. First, designate the pulse
edges you want to measure
between.
C (or D)
D (or C)
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 basis, you should use Free Run.
3. 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
“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 below).
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 exampel). 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, the count
resumes (see lower example).

control bit in your control program.
Soft resets are always level resets,
meaning they hold the count at zero

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 IO 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.

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

Discrete Outputs
The CTRIO module offers four discrete outputs numbered 0, 1, 2,
and 3. The outputs respond to presets assigned by the user in the
Configure IO 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 IO 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 IO 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 elsewhere in this chapter. Pulse ON

I/O Map Dialog
On the main dialog, click the I/O Map button to open the I/O
Map dialog. The I/O Map dialog performs three important
functions for users of DirectLOGIC PLCs.
First, it gives you the opportunity to assign CPU memory
locations for data transfers from the CTRIO module to the CPU
and data transfers from the CPU to the CTRIO module. The
example shown below indicates the V-memory locations of a DirectLOGIC PLC.
The I/O Map also allows you to enable these data transfers. You will need to enable the
data transfers in order to use the CTRIO data within your control program or to make
dynamic changes to the stored CTRIO data or configuration values.
The third important function of the I/O Map is to identify, in a table form, the memory
locations where raw or scaled input values are located and where status and control
bits appear.

Runtime Changes to the Preset Tables
Presets and preset tables can be set up entirely within CTRIO Workbench. You can also
make runtime edits to presets 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).
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
particular sequence:
The command code and associated parameters must be loaded into the appropriate
memory locations.
A Process Command instruction must be passed to the CTRIO module.
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.
Some changes require a combination of Command Codes so those changes must follow
the steps above for each Command Code processed.

Edit Level Response Command
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. 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.
Edit the behavior of a Discrete Output triggered by a Rate Level by using the “Edit Level
Response Command” (Command Code 20Hex).
The Level Behavior setting for Parameter 1 is given in the table below:

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.

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.
3 decimal = 03 Hex = 0000 0011 binary in the high byte, and
10 decimal = 0A Hex = 0000 1010 binary in the low byte.
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 remainder of the Command Code in the low byte.

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.

Pulse Output Commands
The CTRIO module can generate Pulse Outputs based
on predefined user profiles. Using program control
techniques, the Pulse Profiles can also be changed
dynamically during runtime.
CTRIO Workbench 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.
Based on the Workbench configuration, either of the
two Pulse Output channels can output Pulses and
Direction, or Up Pulses and Down Pulses.

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
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 set the Enable Output bit when appropriate. If the Command Error bit is received,
the CTRIO was unable to process the command due to n illegal value in either the
Command Code or parameter files.
DWord and Word values for pulse outputs are considered unsigned integers.

Trapezoid or S-Curve
For predefined Trapezoid or S-Curve profiles, the program needs to prepare the Load
Table command by selecting Command Code = 1 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 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 buy clearing the Enable Output, changing the
direction bit (if desired), and again setting the Enable Output.
Easy step examples are given for PLCs with CTRIO I/O date mapped in the word and CR
bit areas of CPU menmory.

Dynamic Positioning
For Dynamic Positioning, only the motion limits of Min Frequency, Max Frequency, and
Max Acceleration come from the CTRIO Workbench Profile. After loading a Dynamic
Position Profile per the above paragraph, 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 Load/Seek Position bit. This will cause the
CTRIO to set both the Pulses Active and the New Position Loaded bit and begin output
pulses (with the proper direction setting) to achieve the new position.
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 s tate 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.

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.

Pulse Output at Velocity
For motion control directly from the CPU/controller program, use the Pulse Output at
Velocity command (Command = 0005). 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 in 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.

Pulse Output to Input Limit
The Pulse Output to Limit (Command = 6) can be used for Home Search routines where
a relatively low frequency is used to seek a CTRIO discrete input. The CTRIO input must
be assigned for Limit by the CTRIO Workbench utility.
As with Pulse Output at Velocity, set Word Parameter 1 to the desired frequency, Word
Parameter 2 Low Byte to the Duty Cycle, and the High Byte to the Edge to Seek.
The Edge to Seek field reads Word Parameter 2 bits 13 and 12 to determine the edge(s)
on which to terminate Output Pulses, and bits 9 and 8 to determine which CTRIO Input
terminal to use.
