Note
ET-Connection/supply voltage
Installing a supply voltage cable in an ET-connection socket or an ET-connection cable in the
supply voltage loop-through socket can destroy the module.
Observe the correct wiring of the M8 sockets for ET-Connection and the supply voltage.
3.3 Connecting the M12 eCoding plug
The eCoding plug (6ES7194-6KB01-0AA0) stores the PROFIsafe addresses that you assign to
the F-DI 4/F-DQ 2 Fail-Safe module:

The eCoding plug stores the following information:
•
PROFIsafe source address
• PROFIsafe destination address
• Address validity information
The eCoding plug occupies the X40 M12 socket, utilizing a B-coded plug. You use the
eCoding plug to facilitate module replacement.
The eCoding plug stores assigned PROFIsafe source and destination addresses. The "Assign
PROFIsafe address option" is selected in STEP 7 during the F-DI 4/F-DQ 2 Fail-Safe module set-
up. The module checks the PROFIsafe addresses stored in the eCoding plug against the
PROFIsafe reference addresses provided to the module during start-up parameterization.
Protection mechanisms prevent you from damaging the eCoding plug or an I/O channel due
to attempted plugging of the eCoding plug into an I/O M12 socket or plugging of an I/O M12
cable into the X40 socket.
