High-speed Counter/Pulse Output Instructions
Section 3-21
Flags
Example When CIO 000000 turns ON in the following example, SPED(885) starts out-
putting pulses from pulse output 0 in Continuous Mode at 500 Hz. When CIO
000001 turns ON, pulse output is stopped by INI(880).
3-21-2 HIGH-SPEED COUNTER PV READ: PRV(881) (CJ1M-CPU21/22/23
Only)
Purpose PRV(881) reads the following data on the built-in I/O of CJ1M CPU Units.
• PVs: High-speed counter PV, pulse output PV, interrupt input PV in
counter mode.
• The following status information.
Name Label Operation
Error Flag ER ON if the specified range for P, C, or NV is exceeded.
ON if the combination of P and C is not allowed.
ON if a comparison table has not been registered but
starting comparison is specified.
ON if a new PV is specified for a port that is currently out-
putting pulses.
ON if changing the PV of a high-speed counter is speci-
fied for a port that is not specified for a high-speed
counter.
ON if a value that is out of range is specified as the PV for
an interrupt input in counter mode.
ON if INI(880) is executed in an interrupt task for a high-
speed counter and an interrupt occurs when CTBL(882)
is executed.
ON if executed for a port not set for an interrupt input in
counter mode.
