Using Data Areas
The high-speed counter PV is stored in words 248 and 249 as shown below.
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 high-speed counter is not used, words 248 and 249 can be used as
work words.
When the PV is read by executing PRV(62), words 248 and 249 are refreshed
with the same timing.
