X118, X119, external communication
The optional connection point X118/X119 is a Multi-Ethernet interface used to
connect components with Ethernet-based communication (sercos III,
PROFINET IO, EtherNet/IP, EtherCAT) in distributed form.

X118, X119; function, pin assignment, properties
At KMV supply units, the connection points X119 (control unit)
and X103.2 (KMS; alternative: X118 - instead of X103.2 - when
using hybrid cables without communication) have to be used.
Principle of external communica‐
tion
In the case of devices with external communication, the communication sig‐
nals are transmitted in parallel with X103.1 and X103.2 via a circuit board
(see figure: LK_C) to the connection points X118 and X119.
