■Wave output mode
The analog output status changes as shown in the following table, depending on the combination of 'CH1 D/A conversion
enable/disable setting' (Un\G500), 'CH1 Output enable/disable flag' (Y1), and the wave output status.
Execution 'CH1 D/A conversion
status enable/disable setting'
(Un\G500)
'CH1 Output enable/
disable flag' (Y1)
Analog output HOLD/
CLEAR setting
Wave output status
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
*1
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.
*2 Analog output set in 'CH1 Output setting during wave output stop (Un\G524)' is produced.
*3 When an external power supply disconnection or a disconnection is detected, the wave output status transits to the status of under wave
output stop and 0V/0mA is analog output. Subsequently, if the status is recovered from the external power supply disconnected or
disconnection detected status, the analog output value returns to the value before wave output stop. When the CPU module status is
changed from STOP to RUN, the value is analog output according to the settings in 'CH1 Output setting during wave output stop'
(Un\G524).
■Inter-module synchronization 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 HOLD/CLEAR

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.
