Overview
The High-Speed Counter I/O (CTRIO)
module is designed to accept high-speed
pulse-type input signals for counting or
timing applications and to provide highspeed pulse-type output signals for stepper
motor control, monitoring, alarm or other
discrete control functions. The CTRIO
module offers great flexibility for applications that call for precise counting or timing,
based on an input event or for high-speed
control output applications.
The CTRIO module has its own microprocessor and operates asynchronously
with respect to the PLC/controller. This
means that the on-board outputs respond
in real time to incoming signals, so there is
no delay waiting for the PLC/Controller to
scan I/O.
The CTRIO modules offer the following
I/O features:
• Eight DC sink/source inputs, 9-30 VDC
• Four isolated sink/source DC outputs,
5-30 VDC, 1A per point
Inputs supported:
• Two quadrature encoder counters up to
100 kHz, or four single-channel counters up to 100 kHz using module terminals Ch1A, Ch1B, Ch2A and Ch2B
• High-speed edge timers, dual edge
timers, pulse catch, count reset, count
inhibit , or count capture or home
search limits using module terminals
Ch1C, Ch1D, Ch2C or Ch2D
Outputs supported:
• Four independently configurable highspeed discrete outputs or two channels
pulse output control (20 Hz-25 kHz per
channel or 50 kHz if only using one
channel)
• Pulse and direction or cw/ccw pulses
supported for pulse output control
• Raw control of discrete output directly
from user control program
Software
configuration
All scaling and configuration is done via
CTRIO Workbench, a Windows software
utility program. This eliminates the need
for PLC ladder programming or other
interface device programming to set up
the module. CTRIO Workbench runs
under Windows 98/2000/XP and NT
4.0 SP5 or later.

Installation and wiring
AC Drives
The T1H-CTRIO module has two independent input channels, each consisting of four optically isolated input points
(points 1A-1D on common 1M and points 2A-2D on common 2M). The inputs can be wired to either sink or source current.
The module has four optically isolated output points (points Y0-Y3 on isolated commons C0-C3, respectively). The outputs must
be wired so that positive current flows into the Cn terminal and then out of the Yn terminal (see the diagram below and the
schematic on the following page).
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.
See the notes below for further details about power source considerations, circuit polarities, and field devices.

Notes:
1. Inputs (1A, 1B, 1C, 1D and 2A, 2B, 2C, 2D) require user-provided 9-30 VDC power sources. Terminals 1M and 2M are the commons for
Channel 1 and Channel 2 inputs. Maximum current consumption is 12 mA 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
5-36 VDC power sources. The maximum allowable current per output circuit is 1A.
4. User Bus 1 and User Bus 2 are independent 8-wire terminal buses. They can be used for additional power rail connections.

Fill-in-the-blank
configuration software
The CTRIO Workbench is the software utility used 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 Automation Products,
L.L.C. Web site: www.hosteng.com.
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 function boxes prompt
you with selections for supported functions. The
Workbench software automatically disallows any unsupported configurations.

CTRIO Workbench diagnostics and monitoring
The Monitor I/O dialog is accessible from the main Workbench dialog
when the module is in Run Mode. This allows for a convenient way to test
and debug your configuration prior to installation. The Monitor I/O dialog
is divided into three functional areas: Input Functions, Output Functions and
System Functions. The data displayed under the Input Functions tab includes
all input Dword parameters, status bits and the current status of each configured input and output function. The fields displayed under the Output
Functions tab includes all output Dword parameters and configuration information that can be altered during runtime and the bits that indicate
successful transfers or errors. The System Functions can be used to read from
or write to the CTRIO’s internal registers.

High-Speed Counter
High-speed counting
High-speed input operations
The CTRIO can be configured for counting functions for the
use of an encoder input, (up to two quadrature encoders per
module) with available connections for external reset and
inhibit signals. In a simple cut to length application as shown,
the encoder provides an input position reference for the material to the module. The module's high speed outputs are wired
to the cutting device and to the clutch and/or braking device.
When the count from the encoder is equal to a preprogrammed setpoint within the module, the high speed
outputs are activated to stop and cut the material to a repeatable fixed length. Additionally, the clutch/brake signal can be
used for an inhibit signal to not accumulate counts while the
material is being cut.
The CTRIO module is capable of a wide variety of high
speed input and output operations all within one
module. With its flexible 2-channel input and separate
2-channel output design, the CTRIO can satisfy both
high-speed counting, timing, pulse catch operations,
along with high speed discrete output or several profile
choices of pulse output operations. Not all combinations of input functions and output functions are
possible within the resources of the module, but the
following examples are some of the most common
applications for the CTRIO. Check out these examples
and see how they relate to your high speed application
needs.
High-speed timing
The CTRIO can be configured for timing functions
based on both count or rate. Using a common configuration of a proximity switch sensing the teeth on a gear,
the module is able to calculate the velocity of the gear
based on the rate it receives its counts. This value can
be scaled within the module to the engineering units
required for the application.

Pulse output for stepper/servo control
The CTRIO module is capable of multiple configurations for pulse
output control, most often when connected to a stepper or servo
drive system. The module can deliver a pulse output signal up to a
maximum of 25 kHz on two channels with support for pulse-anddirection or CW/CCW pulses. The available profile choices
include Trapezoid, S-Curve, Symmetrical S-Curve, Dynamic
Positioning, and Pulse to Limit. All profiles can be easily configured
using the CTRIO Workbench software with fill-in-the-blank parameter fields and a graphic representation of the selected profile.
Three additional profiles are available that are completely
controlled by the user program (no CTRIO profile is configured).
They are Velocity Mode, Run to Limit Mode and Run to Position
Mode.
Example application
In a simple rotary indexing application, as shown above, a fixed
Trapezoid profile is chosen. The CTRIO for this application is wired
to a stepper drive for pulse-and-direction. The requirement for this
application is to provide a smooth movement of the rotary table to
allow product to be filled into individual containers equal distance
apart. The predetermined number of pulses required for each
movement is entered into the CTRIO Workbench as "Total Pulses"
along with the Starting Frequency, Ending Frequency, and
Positioning Frequency (speed after acceleration). The Acceleration
and Deceleration parameters are entered in units of time, so no
ramp-distance calculations are required. After all parameters are
entered, a graphical representation of the configured profile is
shown automatically. Once the configuration has been downloaded to the module, all that is needed from the PLC CPU is the
Enable Output signal to begin a movement.

Other common pulse output applications:
• S-Curve accel/decel profile for signaling a stepper or servo
drive that needs a curved acceleration and deceleration pro
file, i.e. for diminishing any initial “jerk” upon movement of
static products, boxes on conveyors, liquids in containers on
an indexer, printing registrations, etc.
• Dynamic Positioning for any run-to-a-specific-position
requirement, either by a pre-programmed count of an external
high speed discrete input wired to the module. This is
popular in winding or webcontrol with any dynamic
registration mark or variable speed requirement.
• Home Search routines to seek a home position based on
CTRIO discrete input limit(s).

High-Speed inputs and pulse output
combinations
The flexible design of the CTRIO module allows for combining
high speed inputs and delivering high speed pulse outputs signals
simultaneously. There are limitations to this type of configuration in
that the module does not internally support closed loop control.
Providing closed loop control with the CTRIO involves additional
PLC code to coordinate this control, making the application
subject to the PLC CPU program scan. Simple position/speed
monitoring, via a high speed counting input for non-critical
response while providing pulse outputs to a drive, is easily achievable for the CTRIO.
Master Controller program
Example application
In the simple drill-head application shown above, the CTRIO pulse
outputs are wired to a stepper and/or servo drive. The inputs are
wired to an encoder attached to the lead screw on the movable
portion of the drill-head assembly. The CTRIO module output
pulse train to the drive allows the motor to spin the lead screw
making the drill move forward into the passing material. The
encoder monitors the speed and position of the drill-head. Prox
switches at each end act as limit switches ensuring the drill-head
will not over-travel. A home sensor is positioned in the middle of
the assembly, allowing the PLC to reset the count.
CTRIO pulse output profile
Note: Closed loop control for the CTRIO module
requires control program interaction to
close the loop. This makes the application
subject to the master controller scan.
