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).
DIP switch DIP switch to set the number of the mounting rack.
Socket for external
backup voltage
EXT.BATT.
On the IM 461-0 (order number 6ES7461-0AA00-0AA0) you can
connect external backup voltage (5 V to 15 V) or central backup (see
Installation Manual, Chapter 9) to this socket when you want to
replace the mounting rack power supply. This will ensure backup of
the corresponding EU without interruption. If you use this IM in a
cabinet, you should, for reasons of space, use an angled connector
for the incoming supply.
Front connector X1 Upper connector (input) for the connecting cable from the previous
interface module.
Front connector X2 Lower connector (output) for the connecting cable to the next
interface module or for the terminator.
