Pulse output instructions
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.
