A new node appears under the Onboard I/O node.
By default, the new node is named “Generic Input #1”.
4.
If necessary, click one or two more times the
Generic Input
icon
.
New Generic Input nodes appear under the Onboard I/O node.
By default, the new nodes are named “Generic Input #2” and “Generic Input
#3”.
See the onboard input connections on page 15 (X102 connector).
Do not select the
Power Supply Supervision
option for the onboard inputs
