5.2.3 PROFINET connection
PROFINET is connected via the RJ45 sockets X241 and X242.
For connection of the communication module to the PROFINET fieldbus, a standard Ethernet patch
cable is suitable.
Ethernet cable specification
( 29)
The installation and removal of the Ethernet cables is optimised for the use of connectors in
accordance with the "Automation Initiative of German Domestic Automobile Manufacturers"
(AIDA).
Pin assignment
Tip!
The PROFINET interfaces feature an auto-MDIX function. This function adjusts the polarity
of the RJ45 interfaces so that a connection can be established irrespective of the polarity of
the opposite PROFINET interface and irrespective of the type of cable used (standard patch
cable or crossover cable).
Note!
To prevent the RJ45 socket from being damaged, insert or remove the Ethernet cable
connector straight (at a right angle) into or from the socket.
