at Power Up or when the Unit is restarted *4
*1. The Unit must be in one of the five positions immediately to the right of the CJ1-H CPU Unit or in one of the three positions immediately to the
right of the CJ1M CPU Unit to activate external interrupt tasks. No external interrupt tasks can be activated if the Unit is in any other position
(i.e., 6th Unit position or further away from the CJ1-H CPU Unit, or 4th Unit position or further away from the CJ1M CPU Unit), or if it is on a
CJ-series Expansion Rack.
*2. The maximum number of Units per Rack is also depending on the maximum supply current of the Power Supply Unit and the current
consumption of other Units on the Rack.
*3. The CJ1W-CT021 Special I/O Unit is allocated words for 40 words in the Special I/O Unit (CIO) Area.
*4. The CJ1W-CT021 Special I/O Unit is allocated words for 4 Units in the Special I/O Unit DM Area. From the 400 DM words that are allocated,
the first 113 words are used to make the DM-settings and the remaining 287 words can be used as work-words.

Reset Signals
Every Counter can be reset to zero by (a combination of) the following sources:
• Software Counter Reset Bit
• Digital Input * 1
• Z-Input * 1
Extra Functions
• Programmable Output Pulse * 1:
To every Digital Output an ON-delay and/or a Pulse Duration [1 to 9999 ms] can be applied.
• Rate Measurement * 1* 4 : For every Counter the Pulse Rate can be measured by defining a Time-Window [1 to 9999 ms]. Up to
a maximum of 64 Rate Values are stored in the Rate History Log File. Rate Values from the Rate History Log File can be read using
the IORD-instruction. Additionally for every Counter two Rate Ranges can be defined that control the Outputs according to the measured Rate Value.
• Hysteresis * 1: To prevent Outputs from being switched On and Off by very small fluctuations in the Counter Value around Range
Limits, for every Counter an Hysteresis-value [1 to 255] can be defined (the Unit must in Range Mode).
Noise Filtering Counter Inputs and Digital Inputs
To suppress noise on the signal lines of the Counter Inputs (A and B) and the Digital Inputs (I0 and I1) a Noise Filter can be configured:
• 10 kHz * 1
• 50 kHz (default)
• 500 kHz * 1
For the Digital Inputs the 500 kHz filter can not be selected. The Z-Input Signals of every Counter are filtered with a fixed Noise Filter
of 1 kHz.
Initial Counter Value *4
• The Initial Counter Value * 1 is transferred to the Unit when the Unit is Powered Up or Restarted. The Initial Counter Value is very
useful to overcome problems in case of power failure.
IORD- and IOWR-instructions *4
Run-time * 3 configuration and operation of the High-speed Counter Unit is possible by using IORD- and IOWR-instructions. The
following data can be read or written:
• DM-configuration data * 1
• Range- and Comparison Data * 1
• Captured Counter Value
• Rate History Log File Data * 1
• Counter Value
• (Re) Configure High-speed Counter Unit * 1
• Error Clear
Interrupts of Outputs *4
• The Digital Outputs and the Soft Outputs of the Unit Output Pattern can all be configured to generate interrupts to the CJ1-H/CJ1M
CPU Unit * 1 * 2.
Interrupts of Digital Inputs *4 • The Digital Inputs can all be configured to generate interrupts to the CJ1-H/ CJ1M CPU Unit * 2.
Error History Log Function
• Stores up to 30 error log records
*1. This specification item is only supported for Circular and Linear Counters (not for Simple Counters). For a complete overview of the differences
between Simple and Circular/Linear Counters refer to High-speed Counter Unit Operation Manual (Cat. No. W401).
*2. To activate external interrupt tasks, a CJ1-H or CJ1M CPU Unit must be used. CJ1 CPU Units do not support external interrupt tasks. To
activate external interrupt tasks in a CJ1-H CPU Unit, the CJ1W-CT021 High-speed Counter Unit must be in one of the five positions
immediately to the right of the CJ1-H CPU Unit. For CJ1M CPU Units, the CJ1W-CT021 High-speed Counter Unit must be in one of the three
positions immediately to the right of the CJ1M CPU Unit. No external interrupt tasks can be activated if the Unit is in any other position (i.e.,
6th Unit position or further away from the CJ1-H CPU Unit, or 4th Unit position or further away from the CJ1M CPU Unit), or if it is on a CJseries Expansion Rack.

For CJ1-H CPU Units: External interrupt tasks can be

*3. If an IOWR- or IORD-instruction is used during operation, comparison will stop during instruction execution. Care must be taken, therefore,
with the timing of executing instructions.

Note: As a general guideline it can be stated that if you want the timing requirements for the Counter Inputs to satisfy the above mentioned
specifications, you must pay attention to the type of output driver of the encoder being used, the length of the encoder cable and the
frequency of the count pulses generated. For example, if you use an Open Collector encoder (e.g. E6B2-CWZ6C) at 24 V with 10 m cable,
you can typically generate count pulses up to 20 kHz. Therefore, if you want to generate count pulses with higher frequencies, you should
use a different type of encoder (e.g. E6B2-CWZ1X with Line Driver output or a fast push-pull 24 V encoder, e.g. E6C3-CWZ5GH
(Complementary output)) or reduce the length of the encoder cable.

Note: 1. Every Digital Output has 2 Output drivers available: NPN and PNP (available as separate pins on the front connectors). Every Output
can be separately (DM-) configured for NPN or PNP. By default the Outputs are configured as NPN-output.
2. The Digital Outputs are insulated from the I/O-bus but not from each other. They are not short circuit protected.
3. The Output current must not exceed 200 mA per common (i.e. per 2 Digital Outputs) otherwise the unit will be damaged.
4. The Outputs can be automatically or manually controlled (DM-setting) by using Manual Output Control in CIO.
5. The state control of the Outputs, in case the operating mode of the CPU-Unit is changed from RUN/MONITOR → PROGRAM, an I/O
Bus error or an Overflow/Underflow error occurs, can be configured.
