*8. Unit version 2.0 of built-in EtherNet/IP section: 20 words. 
*9. If the maximum number is exceeded, refreshing will require more than one CPU Unit cycle. 
*10.When changing parameters, however, the EtherNet/IP port where the change is made will be restarted. In addition, a 
        timeout will temporarily occur at the other node that was communicating with that port, and it will then recover 
        automatically.

Pulse I/O Functions

The following functions of CJ2M can be used by installing one or two Pulse I/O Modules. Each module has 10 high-speed inputs and 6 high-speed outputs. Pulse I/O Modules can be installed on CJ2M CPU Units with Unit Version 2.0 or Later.
  • The inputs can be used as general-purpose inputs, interrupt inputs, quick-response inputs, high-speed counters, or origin search inputs.
  • The outputs can be used as general-purpose outputs, pulse outputs, origin search outputs, or PWM outputs.

One Pulse I/O Module can be mounted

Interrupts
An interrupt task is executed when preset comparison conditions for a high- 
speed counter are met. 
Target-value comparison: The interrupt task is executed when the count 
matches a specified value.
