Pulse Outputs Section 5-2
MODE CONTROL: INI(880) In addition to the various interrupt and high-speed counter functions, INI(880)
can be used to change the pulse output PV or stop the pulse output.
Note This section explains the functions related to pulse outputs only. For details on
the INI(880) instruction’s high-speed counter or interrupt functions, refer to
6-1
Interrupt Functions or 5-1 High-speed Counters .
HIGH-SPEED COUNTER
PV READ: PRV(881) In addition to its interrupt and high-speed counter functions, PRV(881) can be
used to read the pulse output PV or pulse output status information.
The status of the following flags is read as status information:
• Pulse Output Status Flag
• PV Underflow/Overflow Flag
• Pulse Output Amount Set Flag
• Pulse Output Completed Flag
• Pulse Output Flag
• No-origin Flag
• At Origin Flag
