Signaling Contact - Siemens SCALANCE X-200RNA Operating Instructions Manual

Connecting up

6.2 Signaling contact

6.2 Signaling contact
The signaling contact (relay contact) is a floating switch with which error/fault states can be
signaled by breaking the contact.
The signaling contact is connected to a 2- or 3-pin plug-in terminal block. Usable cable cross-
section 0.25 to 2.5 mm
Coding
With the SCALANCE X204RNA EEC the supplied plugs and the socket on the device for the
signaling contact match in their coding.
The plug and socket for the power supply are coded differently from the connection of the
signaling contact. The plug for power supply and signaling contact cannot therefore be
interchanged.
You can use non-coded plugs in coded sockets and coded plugs in non-coded sockets.
Pin assignment
Pin number Pin assignment of the SCALANCE X 204RNA
Pin 1 F1 (NO contact / NC contact if a fault occurs)
Pin 2 F2
Pin 3 -
The following errors/faults can be signaled by the signaling contact:
● The failure of a link at a monitored port.
● The failure of one of the two redundant power supplies (SCALANCE X204RNA only).
● The loss of the entire power supply
● Internal error
● Incompatible C-PLUG was inserted.
The connection or disconnection of a communication node on an unmonitored port does not
lead to an error message.
The signaling contact remains activated until the error/fault is eliminated or until the current
status is applied as the new desired status using the SELECT/SET button.
