Section 5-3
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
• Pulse Output Stopped Error Flag
Note
This section explains the functions related to pulse outputs only. For details on
the PRV(881) instruction’s high-speed counter or interrupt functions, refer to
5-1 Interrupt Functions or 5-2 High-speed Counters.
