The following errors/faults can be signaled by the signaling contact:
● The loss and the establishment of a link on a monitored port.
● The failure of one of the two redundant power supplies.
● The loss of the connection to the controller in PROFINET IO mode.
● The redundancy manager signals an error
Note
SCALANCE X204 IRT PRO, SCALANCE X202-2P IRT PRO and S

IRT PRO have no redundant power supply
● Incompatible C-PLUG was inserted.
The connection or disconnection of a communication node on an unmonitored port does not
lead to an error message.
