RJ45 to M12 converter
For PROFINET installations, it may be necessary to change
between RJ45- and M12 connection technology.
Example for use: connections between devices in the switch
cabinet with RJ45 connection and IP65/IP67 devices with
M12 connection.
Cable specification
Use shielded Industrial Ethernet cables of category Cat 5 or
higher. You can find details regarding cable specification in
Tab. 1/6.
The bus nodes for PROFINET support crossover detection
("Auto-MDI"): You can either use patch cables or crossover
cables for connecting your bus node to a network or PC.
Make sure that the function "Autonegotiation/Autocrossover"
is activated in your controller software if you use patch and
crossover cables in the same system. You will find additional
instructions on this function in section 2.6.4.
Crossover detection is not available in the remote I/O operat-
ing mode with additional function "Fast start-up" (FSU):
