17 Communication interface PROFINET

17.1 Bus line with copper cable

This interface is located on the module in the form of two 8-pin RJ45 sockets on the bottom side
of the housing.
•
Plug the PROFINET-connector(s) onto the RJ45 socket labelled "RJ45 PROFINET-IO" until it
snaps in.
•
Please make sure that the length of the line to the adjacent Ethernet participants does not fall
below 0.6 m.

17.2 Line routing, shield and measures to combat interference voltage

This chapter deals with line routing in the case of bus, signal and power supply lines, with the aim
of ensuring an EMC-compliant design of your system.

17.2.1 General information on line routing

Inside and outside of cabinets
In order to achieve EMC-compliant routing of the lines, it is advisable to split the lines into the fol-
lowing line groups and to lay these groups separately.
 Group A:
• shielded bus and data lines (e. g. for RS232C and printers etc.)
• shielded analogue lines
• unshielded lines for DC voltages 60 V
• unshielded lines for AC voltage  25 V
• coaxial lines for monitors
 Group B: • unshielded lines for DC voltages  60 V and 400 V
• unshielded lines for AC voltage  24 V and  400 V
 Group C:
• unshielded lines for DC voltages > 400 V
The table below allows you to read off the conditions for laying the line groups on the basis of the
combination of the individual groups.
Group A
Group A 1
Group B 2
Group C 3
Table 3: Line laying instructions as a function of the combination of line groups
1) Lines may be laid in common bunches or cable ducts.
2) Lines must be laid in separate bunches or cable ducts (without minimum clearance).
3) Lines must be laid in separate bunches or cable ducts inside cabinets but on separate cable
racks with at least 10 cm clearance outside of cabinets but inside buildings.
