Product Characteristics
4.5 SCALANCE X101-1POF
Signaling Contact
The signaling contact is connected to a 2-pin plug-in terminal block. The signaling contact
(optical relay contact) is a floating switch with which error/fault states are signaled by contact
separation.

The following errors/faults can be signaled by the signaling contact:
•
The failure of a link at one of the two monitored ports.
•
The failure of one of the two redundant power supply units.
Connecting or disconnecting a communication node at an unmonitored port does not cause
an error message.
The signaling contact remains activated until the error/fault is eliminated or until the current
status is applied as new desired status by the button.
When turning off the device, the signaling contact is always activated (open).
