Synchronized Pulse Control (CPM2A/CPM2C Only)

Words 248 and 249 are refreshed with every scan, so there may be a discrepan-
cy from the exact PV at any given time.
When the PV is read by executing PRV(62), words 248 and 249 are refreshed
with the same timing.
Read Synchronized Control Status
This function reads the synchronized control status.
Using an Instruction

1: Pulse output in progress
Using Data Areas
As shown in the following illustration, the status of pulse output 0 is stored in
AR 1115, and the status of pulse output 1 is stored in AR 1215.
AR 11
Status of pulse output 0
0: Stopped
1: Output in progress
AR 12
Status of pulse output 1
0: Stopped
1: Output in progress
AR 1115 and AR 1215 are refreshed once each cycle, so there may be a discrep-
ancy from the exact PV at any given time.
When the PV is read by executing PRV(62), AR 1112 and AR 1212 are refreshed
immediately.
