Reads the PV.
Reads status.
Reads range comparison results.
P = 0000 to 0003: Reads the output frequency of pulse output 0 to 3.
C = 0003 hex: Standard operation
P = 0010: Reads the frequency of high-speed counter input 0 (high-speed counter 0 only).
C = 0003 hex: Standard operation
C = 0013 hex: 10-ms sampling method for high frequency (supported only by CJ1M CPU Units with unit version 3.0 or
later or CJ2M CPU Units)
C = 0023 hex: 100-ms sampling method for high frequency (supported only by CJ1M CPU Units with unit version 3.0 or
later or CJ2M CPU Units)
C = 0033 hex: 1-s sampling method for high frequency (supported only by CJ1M CPU Units with unit version 3.0 or

• ON if the specified range for P or C is exceeded.
• ON if the combination of P and C is not allowed.
• ON if reading range comparison results is specified even though range comparison is not being executed.
• ON if reading the output frequency is specified for anything except for high-speed counter 0.
• ON if specified for a port not set for a high-speed counter.
• ON if executed for a port not set for an input interrupt in counter mode.
• For a CJ2M CPU Unit, ON for any function that uses I/O on the Pulse I/O Module even if a Pulse I/O Module is not
mounted.
• OFF in all other cases.
• ON if a high-frequency method is specified for reading the frequency of high-speed counter 0 and the data could
not be read dependably within the sampling time because the counter value was reset.
• OFF in all other cases.
