A module has not yet completed the initialization process
C2 LED
(green) Line 2 (via front connector X2, connection 2) is correct.
C2 LED
(flashing

Front
connectors X1
and X2
Connector (output) for line 1 and line 2
X1 = upper front connector; X2 = lower front connector
Operator Controls and Indicators of the Receive IM
INTF LED (red) Lights up if a rack number > 21 or = 0 was set.
Lights up if you have changed the rack number under voltage.
EXTF LED
(red) Lights up in the event of an external fault (line fault, for example, if the
terminator is not inserted or if a module has not yet completed the
initialization process, but not when the CC is switched off)
5 VDC (green) Power supply in the EU is correct.
DIP switch DIP switch to set the number of the mounting rack.
Front
connector X1 Upper connector (input) for the connecting cable from the previous
interface module.
Front
connector X2 Lower connector (output) for terminator. The front connector X2 is no
longer required for the IM 461-1 (order number
6ES7 461-1BA01-0AA0). The terminator (6ES7461-1BA00-7AA0)
previously required is now integrated in the module.
!Caution
Modules can be damaged.If you want to connect an EU via the IM 461-1 interface module and use a powersupply module in this EU, you might damage the modules.Don’t use a power supply module in an EU that you want to connect to the CC viathe IM 461-1 interface module.
