Using Data Areas
As shown in the following illustration, the pulse output PV for pulse output 0 is
stored in words 228 and 229, and the pulse output PV for pulse output 1 is stored
in words 230 and 231.
Pulse Output 0
Word 228
Word 229
Words 228 to 231 are refreshed with every scan, so there may be a discrepancy
from the exact PV at any given time.
Words 228 to 231 cannot be used as work words even when pulse outputs are
not being used.
When the PV is read by executing PRV(62), words 228 to 231 are refreshed with
the same timing.
Read Pulse Output Status
This function reads the pulse output status.

Using Data Areas
As shown in the following illustration, the pulse output status for pulse output 0 is
stored in AR 11, and the pulse output status for pulse output 1 is stored in AR 12.
AR 11: Pulse output 0
AR 12: Pulse output 1
