Explanation
1. This instruction is for AS02HC-A only. You can start, stop the counter as well as set up and edit the counter value.
This instruction is available for PLC with FW V1.08.or later and ISPSoft V3.10 or later.
2. Before executing this instruction, you need to put the setting values in Action and Value. Once En is triggered, the
PLC scans the values in Action and Value immediately. If you need to edit the values in Action and Value, set new
values in Action and Value and set the Update to ON. Once the values in Action and Value are updated, the Update
switches to OFF.
3. Module: The module number that is connected to the right side of PLC directly or connected to the remote module
that acts as PLC, e.g. the first connected module is module number 1, the second connected module is module number
2. Up to 32 modules can be connected and counted and each type of modules should be included in the count.
4. ChNo: Channel number for counter, channel 1 is number 1; channel 2 is number 2.

Set up a new counter value in Value
Note: If you are using SSI (serial synchronous interface) encoder
and the setting of counter mode is in Absolute Position, the Action
mode here is invalid.
When the setting of counter mode is in Absolute Position, you can
set the counter offset value of the SSI encoder. If you set the offset
value in Value, the current counter value (CurCnt) is the sum of
