Analog Output HOLD/CLEAR Function

Whether to hold or clear the output analog value can be set, according to the CPU module operating status (RUN,
STOP, or stop error).
(1) Combination of analog output status
The following table shows how the analog output status changes, depending on the combination of settings for

occurs
*1 This is when the program operation is not completed within the estimated time in the CPU module due to a hardware
failure in the D/A converter module. In this case, Remote READY (RXB) and the RUN LED of the D/A converter module
turn off.
*2 The analog output HOLD/CLEAR function may be executed even when the D LINK LED is on if the cyclic data update
watch time is set. For details, refer to the following.
