registers and special internal relays, use the PLC-independent system variables. You can
insert system variables directly into the POU body: Use the "Variables" dialog without entering
a declaration in the POU header. Please refer to the FPWIN Pro online help for detailed
information on using system variables.
Using the pulse output control flag
The relay is TRUE if a pulse output instruction is being executed. Use this flag to prohibit the
simultaneous execution of other high-speed counter instructions and pulse output instructions
on the specified channel, and to verify completion of the execution.
NOTE
The status of the high-speed counter control flag or pulse output control flag
may change while a scan is being carried out. For example, if the flag is used
more than once as an input condition, different statuses may exist within one
scan. To ensure proper execution of the program, the status of the special
internal relay should be copied to a variable at the beginning of the program.
