Inputs Overview tab
The upper part of this tab contains the general input layout. The auxiliary supply
voltage for each group of optocouplers (with a common pole) is placed below this.
The combo box is used to select a new value for the auxiliary supply voltage
(battery voltage).
In the matrix below, all the input signals assigned to the device are listed.
Delete a Signal:
Select a row in the list and click the button "Delete".
Optocoupler event configuration:
Select a column (e.g. OC08) and click the button "OC event config.".
In addition to events generated by function signals, a physical input can also be
configured as an event. This is of advantage, for example, when several signals are
assigned to a physical input or when ambivalent signals from isolators or circuit-
breakers need to be recorded.
To configure a physical input as an event select it in the list and click on "OC event
config." to open the "Configuration of events" window.
