The variables that can be set for the Digital channels are:
Threshold voltage, measured in millivolts – the example is 2.5V. On an
expansion port any value other than 0 sets the threshold to 1 (ON)
‘Low to high transition only’ – When an input goes from below the threshold to
above the threshold, then it will trigger the alarm
‘High to low transition only’ – When an input goes from above the threshold to
below the threshold, then it will trigger the alarm
‘Any transition’ – When an input crosses the threshold in any direction, it will
trigger the alarm
Low to high event message
The text entered for this parameter will be displayed on the RTU when the input
is in an ON (1) state. The RTU will transmit ON to the host system which then in
turn will decide what to display to the remote user.
High to low event message
The text entered for this parameter will be displayed on the RTU when the input
is in an OFF (0) state. The RTU will transmit OFF to the host system which then
in turn will decide what to display to the remote user.
Callout delay (in minutes)
