Nomenclature Section 1-2
1-1 Introduction
The C200H-CT001-V1 and C200H-CT002 are Special I/O Units for C200H PCs.
The C200H-CT001-V1 can be connected directly to an incremental encoder
with an open-collector output or source output to function as a high-speed, reversible counter capable of counting at a maximum of 50 kcps.
The C200H-CT002 can be connected directly to an incremental encoder with an
RS-422 line driver output or through an Encoder Adapter to an incremental encoder with a open-collector output to function as a high-speed, reversible counter capable of counting at a maximum of 75 kcps.
The C200H-CT002 is more resistive to noise than the C200H-CT001-V1 and
should be used wherever excessive cable length or a noise-prone environment
is anticipated. Unless otherwise specified, all information presented applies to
both High-Speed Counter Units. Both the High-Speed Counter Units are referred to generically as the Counter Unit.
1-2 Nomenclature
The nomenclature is the same for both the C200H-CT001-V1 and the C200HCT002. The C200H-CT001-V1 is shown below.

System Configuration Section 1-3
1-3 System Configuration
Example Configuration The following example system configuration uses the Counter Unit to deter-
mine whether or not product length is acceptable. The length of the products
passing by on the conveyor is measured by using the output from a photoelectric switch to initiate and end counting of pulses output from an encoder.
Product length is checked against standards and the product is ejected if it is
out of the acceptable range.

Many other applications are possible by combining other types of inputs and outputs. Refer to Section 4 Data Allocation and Operating Modes for other application examples.
Maximum number of
Special I/O Units per PC
A maximum of 10 Special I/O Units, including Position Control Units, Counter
Units, etc., can be mounted under the same PC, regardless of whether they
are on the CPU Rack, the Expansion I/O Rack, or the rack containing a Remote I/O Slave Unit controlled by the PC. No more than four of these can be
mounted onto any one rack containing a Remote I/O Slave Unit.
Mounting Location The Counter Unit can be mounted to any but the 2 rightmost CPU Rack slots.
Mounting the Counter Unit to either of these slots will prevent you from
mounting devices directly to the PC’s CPU.
The back panel DIP switch must be set before the Counter Unit is mounted.
(Refer to 2-1 Switch Settings.)
3
Operating Modes Section 1-4
1-4 Operating Modes
The Counter Unit can be operated in any one of the six operating modes described below. External outputs are available in only 3 modes: linear, circular,
and preset. The function of these outputs depends on the mode. (The mode is
selected using the mode selector on the front panel of the Counter Unit, as described in 2-1 Switch Settings.) The following is merely an introduction to the op-
erating modes, all of which are covered in detail in Section 4 Data Allocation and
Operating Modes.
Linear Mode In linear mode, the counter value is incremented and decremented between
–8,388,608 and 8,388,607 and is continually compared with preset ranges.
When the counter value is within a range (or ranges), specified outputs are
turned ON. The same output may be specified for one or more overlapping
ranges, in which case the output will be turned ON whenever the counter value i s
within one or more of the ranges.
A maximum of 16 ranges may be specified, each with upper and lower limits.
These limits must be within the counter range, i.e., between –8,388,608 and
8,388,607. Data can be transferred from the PC to change range limits or to set
the present counter value as desired.
Circular Mode In circular mode, the counter value restarts from zero after reaching a preset
maximum value or returns to the preset maximum value when the counter
value is decremented past zero. In all other respects, including data transfer,
circular mode functions exactly as the linear mode. The preset maximum value must be between 0 and 65,535.
Preset Mode In preset mode, the counter value is normally decremented from a preset
value (between 1 and 8,388,607) to zero, although it can also be incremented. During this decrement phase, a total of 3 outputs may be switched ON
and OFF according to ON/OFF counter values. When the counter value
reaches zero, a total of 4 outputs may be turned ON, either indefinitely or for
a preset time, T. Data can be transferred from the PC to change ON/OFF
counter values as desired.
Gate Mode Two types of gate mode operation are available on the C200H-CT002: nor-
mal and cumulative. Only the normal type is available on the C200HCT001-V1. In normal gate mode, pulses are counted while control input IN1
(the count signal) is ON. The counter value is retained when input IN1 goes
OFF until input IN1 goes ON again, at which point counting restarts from
zero. In the cumulative type, control input IN1 serves as the reset signal and
counting continues while control input IN2 (the count signal) is ON. Each time
input IN2 is turned ON, counting continues from the current counter value
until it is reset to zero by input IN1. In either type of gate mode, the counting
range is between –8,388,608 and 8,388,607 and counting may be in either
direction. This mode does not support data transfer or external outputs from
the Counter Unit.
Latch Mode In latch mode, counting begins from zero when control input IN1 (count sig-
nal) is turned ON and ranges between –8,388,608 and 8,388,607. Pulses are
counted continuously (regardless of whether input IN1 is ON or OFF) , but
the current counter value is always the counter value latched the last time
control input IN2 (the latch signal) was turned ON, i.e., the current counter
value remains unchanged while the latch signal (control input IN2) is ON and
is updated to the actual count while the latch signal is OFF. Counting may be
restarted from zero at any time be activating control input IN1. Control inputs
4
Operating Modes Section 1-4
IN1 and IN2 may originate either externally or internally. This mode does not
support external outputs from the Counter Unit or data transfer.
Sampling Mode In sampling mode, pulses are counted for a preset interval after control input
IN1 (the count signal) is turned ON. Counting may be in either direction.
Counting always begins at zero and ranges between –8,388,608 and
8,388,607. The time interval must be between 10 and 9,999 ms.
Control input IN1 may originate either externally or internally. This mode does
not support external outputs from the Counter Unit or data transfer.

Use wire with a cross-sectional area of 0.3 mm
or less. When soldering, do not
short-circuit an adjacent terminal; cover the soldered section with an insulation
tube. When using multicore cable, wire output and input cables separately.

Wiring Precautions For the C200H-CT001-V1, the terminals that are used depend upon the pow-
er supply of inputs A, B, and Z.
For the C200H-CT002, inputs A, B, and Z must be line driver inputs
(Am26LS31-compatible). Positive and negative terminals must be wired correctly. The terminals that are used depend upon the power supply of the control
inputs. Be careful to connect to the correct terminals. Supply only one voltage for
12
Wiring Section 2-2
each input. The terminals for output power supply , 5 t o 2 4 VDC and COM (0 V),
are separated into two: those for outputs 0 through 7. These are not interconnected internally. If the 5 to 24 VDC and COM (0 V) terminals for the output power supply are connected incorrectly, an internal fuse will burn out, preventing operation. This fuse is not user serviceable. This fuse will also burn out if the output
current exceeds 0.5 A/common, again preventing operation. When wiring inputs
A, B, and Z, the following measures must be taken to prevent interference from
noise:
1, 2, 3... 1. Use shielded twisted pair cable and ground the shield.
2. Keep wiring as short as possible and do not place lines parallel to pos-
sible sources of noise, such as power lines.
3. Use a stabilized power supply that is independent from other input and
output power supplies.
The external power supply must be greater than or equal to the load power supply. (An error may occur if the external power supply is less than the load power
supply .) I n the example on the following page, E1 must be greater than or equal
to E2.

Input and Output Circuits Actual pin numbers are arranged in order from the top of the connector start-
ing with A20 and B20. For each input, connect the 0-V terminal and only one
of the other terminals, i.e., do not supply more than one voltage for any input.
The circuits are shown on the following pages.
