Note: there is a time difference between meeting the set value and for the action to take place. Up to 100 us of time
difference can be expected.
11. Set the value in Yno1 and Yno2 to assign the output points Y0.0, Y0.1, Y0.2, and Y0.3. You can have two sets of
values (Yno1 and Yno2) to achieve two sets of comparisons. After this instruction starts to execute, you cannot use
HCDO instruction to control the output points.

12. The counter value either by counting up or counting down met the set value is a MATCH. The flags of Match 1 and
Match 2 are the indicators. When the counter value met the set value, its corresponding Match 1 or Match 2 flag will
be ON. Either one of the followings occurs, the flags of Match 1 and Match 2 will be cleared to OFF, when the PLC
CPU stops, clears the counters, DHCCMP instruction switches from OFF to ON, or Update flag is set to ON.
13. The flags of Match 1 and Match 2 can be used for interrupt devices I, ranging from I400 to I431.
Note: The frequency of the interrupt device I with the same numbering should not be higher than 800Hz.
14. If you stopped executing the instruction, its relative compared values and its output function will stop updating.
15. Refer to the following table for more details when any of the Error flag is ON.
