When a disconnection is detected
When a disconnection is detected during the wave output, the wave output status of the channel where the disconnection was
detected becomes the during wave output stop (the wave output stops). The wave output does not automatically restart even
after the recovery from the disconnection.
To restart the wave output, follow the procedure below.
1.
Set 'CH1 Wave output start/stop request' (Un\G462) to Wave output stop request (0).
2.
Eliminate the cause of the disconnection to restore the connection.
3.
Turn on and off 'Error clear request' (YF).
4.
Check the status of the module and external devices.
5.
Change the value in 'CH1 Wave output start/stop request' (Un\G462) from Wave output stop request (0) to Wave output
start request (1).
Wave output start/stop request cannot be accepted during disconnection.

Wave data
'Output according to the
setting of 'CH1 Output
setting during wave
output stop' (Un\G524)
(1) 0V/0mA is output in analog.
(2) When a disconnection is detected, wave output stops.
(3) Since a disconnection was detected and the wave output has stopped, change 'CH1 Wave output start/stop request' (Un\G462) to Wave output stop request
(0).
(4) The wave output does not restart even after the recovery from the disconnection.
(5) To restart the wave output, turn on and off 'Error clear request' (YF). After that, change 'CH1 Wave output start/stop request' (Un\G462) to Wave output stop
request (0), and then change it to Wave output start request (1) again.
