(1) 'Transistor output monitor ON delay time setting' (Un\G307)
'Transistor output monitor ON delay time setting' (Un\G307) allows users to configure the setting considering the delay time
(response delay/scan time delay) of actual transistor outputs. ( Page 227 Transistor output monitor ON delay time setting)
This flag can be used for the program that judges a disconnection of transistor output by monitoring ON delay output flag and
inputs from external sensors.
For details on the ON delay output function, refer to the following:
