14.8 Input / Output Mapping

The Input Mapping / Output Mapping Tabs enable you to manage the mapping of the available 16
+ 16 Digital Inputs (DI) and Digital Outputs (DO) with predefined meanings. The mappings are not
configurable when one of the four available Single-line feeder diagrams is ticked in the General
Settings page, while they can be fully configured by choosing the "Free" scheme.
Refer to schematic drawings 1VCD400060 dor withdrawable version and 1VCD400089 for fixed
version for DI/O wiring and examples of meanings assigned to fixed DI/Os.
14.8.1 Digital Input Mapping
The configuration matrix provides the 16 available DIs in the columns and a choice of possible
meanings in the rows. When a box identifying a column and a meaning is ticked, DI processing
is enabled. For standard DIs, when the input signal goes High (i.e. an AC/DC voltage over the
activation threshold of about 20 V is applied) for at least 10 ms (20 ms for Open Commands), the

In the example below, when DI2 goes high a CB Close command will be performed.
Meanings with the prefix "#" are negated - they will be activated for a transition of the signal from
high to low. In the example below, DI1 will always be supplied with a voltage above the activation
threshold (e.g. the panel auxiliary supply); when that signal is cut for at least 5 ms, the input will be
valid, the corresponding meaning will be true and the specific function will be performed - in this
case opening of the CB.
