Analog Output HOLD/CLEAR Function

Common
Set whether to hold or clear the analog output value that has been output when the operating status of the CPU module is
RUN, STOP, or stop error.
The analog output HOLD/CLEAR function setting status can be checked with 'CH1 HOLD/CLEAR function setting monitor'
(Un\G431).
Operation
Analog output status when the operating status of the CPU module is RUN, STOP, or stop error varies depending on the
operation mode.
■High-speed output mode or normal output mode
The analog output status changes as shown in the following table, depending on the combination of the settings for 'CH1 D/A
conversion enable/disable setting' (Un\G500) and 'CH1 Output enable/disable flag' (Y1).
Execution 'CH1 D/A conversion enable/
status disable setting' (Un\G500)
'CH1 Output enable/disable
flag' (Y1)

Analog output produced when the CPU module is in
the RUN state
Analog output produced when the CPU module is in
the STOP state
Analog output produced when the CPU module is in
the stop error state
Analog output status when 'External power supply
READY flag' (X7) is off
Analog output status when 'Disconnection detection
signal' (XD) is on
Analog output status when a watchdog timer error
occurs
*1 The watchdog timer error is an error which occurs when internal processing is not normally carried out. When a watchdog timer error
occurs, 'Module READY' (X0) turns off and RUN LED of the D/A converter module turns off.
