*1 The error occurs due to a hardware failure of the D/A converter module or other causes. 'Module READY' (X0) and the RUN LED of the
D/A converter module turn off.
When a watchdog timer error occurs, 'Module READY' (X0) and the RUN LED of the D/A converter module turn off.
Setting procedure
Set "Analog output HOLD/CLEAR setting" to "HOLD" or "CLEAR".

Precautions for when the remote head module has been mounted
When the D/A converter module has been mounted on the remote head module, set whether to hold or clear the analog
output value that has been output when the host station is disconnected with "CPU error output mode setting" of the module
parameter.
The following describes the settings required for using "CPU error output mode setting".
• Enable the station-based block data assurance for cyclic data on the sending side.
• To hold the analog output value, set "CPU error output mode setting" to "Hold". The analog output HOLD/CLEAR function
setting is disabled.
This setting is enabled for each module and cannot be set for each channel. To match the output status of when a stop error
occurs or the CPU module is in the STOP state and that of when the host station is disconnected, set "Analog output HOLD/
CLEAR setting" to the same value in all the channels.
Operating status
The analog output value is held.
The analog output value is cleared.
(The offset value is output.)
*1 "CPU error output mode setting" is enabled in the following cases.
 When the host station is disconnected due to a network error
 When the data link is stopped by the CC-Link IE Field Diagnostics of the engineering tool
