Multi-voltage and Supply Monitor Sub-functions
Original instructions
About us
Overview
To adapt to different voltage ranges, the module supports 3 ranks for 5 rated voltages. This option is available for time stamping, discrete input, and counter functions.
The rated voltage configuration acquires the supply monitor function, which alarms the power interruption case for each rank.
The configuration allows disabling the supply monitor, otherwise the error message will be denoted by the variable (if enabled).

NOTE: If the Supply monitoring is enabled, the input state of each discrete channel is forced to 0 when a field supply failure is detected and the module stops the event detection until the field power supply recovers.
If the last input value is 1, then an event is generated when the input state is forced to 0 but the TimeAccuracy for this event shows an IO Channel error.
