■If the CPU module status was changed during output
When the CPU module status was changed during wave output, after terminating the wave output, it operates as follows
depending on the analog output HOLD/CLEAR function setting.
• For the previous value
If the CPU changes from RUN to STOP, the wave output terminates and the value immediately before STOP is held. When
'CH1 Output enable/disable flag' (Un\G70, b1) is turned on with the CPU module changed from STOP to RUN, the output
changes as per the setting of 'CH1 Output setting during wave output stop' (Un\G524). Wave output does not restart.
To restart the wave output, change 'CH1 Wave output start/stop request' (Un\G462) from Wave output stop request (0) to
Wave output start request (1) again.
