Enable Input
To allow the RTU to report an alarm from this input without being polled, the input must be
enabled.
Disable Input
If the input is disabled, its status will still be sent during a poll response, but any change in
state of the input will not cause the RTU to transmit an alarm.
High Threshold
If the voltage being measured exceeds this threshold and the input is enabled, the RTU will
automatically report an alarm. The threshold value is 0-255, 0 corresponding to 0 volts and
255 corresponding to 5 volts.
Low Threshold
If the voltage being measured drops below this threshold and the input is enabled, the RTU
will automatically report an alarm. The threshold value is 0-255, 0 corresponding to 0 volts
and 255 corresponding to 5 volts.
The threshold values set the limit. A low threshold of 0 and a high threshold of 255 effectively
disable the alarm since these values cannot be surpassed.
