Function and operation explanation
1. 32-bit operation (DHSCS)
When the current value of a high speed counter of the device specified by becomes the comparison
value of the device specified by (for example, when the current value changes from "199" to "200" or
from "201" to "200" if the comparison value is K200), the bit device specified by is set to ON without
regard to the operation cycle. This instruction is executed after the counting processing in the high speed
counter.
Operation
When the current value of the high speed counter C235 changes from "99" to "100" or from "101" to "100",
Y010 is set to ON (output refresh).
