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).
@SPED
Pulse output 0
#0000
CW/CCW method, CW, Continuous Mode
#0000
D00100
@INI
Pulse output 0
#0000
Stop pulse output

PVR(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.
Status type
Pulse output status
High-speed counter input status Comparison In-progress Flag
PWM(891) output status
• Range comparison results
• High-speed counter frequency for high-speed counter input 0.
This instruction is supported by the CJ1M-CPU22/CPU23 CPU Units only.
