Changing the module setting
The contents registered by the function block (FB) for the wave output data registration need to be enabled by turning on and
off 'Operating condition setting request' (Y9). When the setting is enabled, the analog output value of the CH1 where the D/A
conversion is enabled varies depending on the 'CH1 Output enable/disable flag' (Y1) status as shown below.
• 'CH1 Output enable/disable flag' (Y1) is off: The offset value is output.
• 'CH1 Output enable/disable flag' (Y1) is on: A value is output according to the setting of 'CH1 Output setting during wave
output stop' (Un\G524).

(1) Set 'CH1 D/A conversion enable/disable setting' (Un\G500) to D/A conversion enable (0), and then turn on and off 'Operating condition setting request' (Y9).
(2) Set 'CH1 D/A conversion enable/disable setting' (Un\G500) to D/A conversion disable (1), and then turn on and off 'Operating condition setting request' (Y9).
With the wave output function being used, only when the wave output is stopped in all the channels (During
wave output stop (0) is set to CH Wave output status monitor in all the channels), the parameter setting can
be enabled by turning on and off 'Operating condition setting request' (Y9).
When 'Operating condition setting request' (Y9) is turned on and off with a channel being set to a value other
than During wave output stop, an operating condition setting request error in a state other than wave output
stop (alarm code: 0B0H) occurs. The parameter setting cannot be enabled in this case.
