Details of special relays/special registers

Details of special relays/special registers used in PWM output are explained below.
Operation monitor
This device is for monitoring the operation/stopped status of PWM output.
■Corresponding devices
The device numbers corresponding to each channel are as follows.
CPU module
CH1 CH2 CH3
SM5300 SM5301 SM5302
■Update timing
The timing of device update is as follows.
ON
• PWM output driven by HIOEN/DHIOEN instruction
• PWM/DPWM instruction ON execution
PWM output complete flag
This device is for monitoring the completion status (normal completion) of PWM output.
■Corresponding devices
The device numbers corresponding to each channel are as follows.
CPU module
CH1 CH2 CH3
SM5316 SM5317 SM5318
■Update timing
The timing of device update is as follows.
ON
• At execution of the PWM/DPWM, HIOEN/DHIOEN instruction or the END
processing after the output of the specified pulse count is output
If the number of output pulses is set to "0" (unlimited output), PWM output complete flag is not turned ON.
