This instruction is for AS02HC-A only. The counter value either by counting up or counting down met the set value is

a MATCH. Once you have a MATCH, the system reacts accordingly to what you have set, including counter actions

and which output point to output. This instruction is available for PLC with FW V1.08.or later and ISPSoft V3.10 or

Use this instruction with DHCCNT instruction. When executing DHCCNT instruction, the counting starts. And then you

can use DHCCMP instruction to do the comparison.

Before executing this instruction, you need to set up Comp1, Comp2, Action1, Action2, Yno1, and Yno2. Once En

is activated, the PLC scans the values in Comp1, Comp2, Action1, Action2, Yno1, and Yno2 immediately.

You can edit the values in Comp1, Comp2, Action1, Action2, Yno1, and Yno2 during operation. Set new values and

set the Update to ON. Once the values are updated, the Update, Match1 and Match2 switch to OFF.

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.

ChNo: Channel number for counter, channel 1 is number 1; channel 2 is number 2.

Comp 1and Comp 2 are the values for comparison (The value in Comp 1 and Comp 2 should be different.). If the

counter value of ChNo met the set value, its corresponding flag Match 1 / Match2 will be ON. The appointed output

point by Yno1 and Yno2 reacts according to the settings for Action.
