PROFINET
You may operate modules with PROFINET interfaces only in LAN networks (Local Area
Network) in which all the connected nodes are equipped with a SELV/PELV power supply
(or equivalent).
A data transfer terminal (modem, for example) is required to access the WAN (Wide Area
Network) in order to ensure compliance with this safety standard.
Requirements
The CPU (including bus module) and the connection module CM CPU 2PN M12, 7/8" are
mounted on the module rack.
Tools required
● Screwdriver
● Insulation stripping tool for wiring if you are assembling the cables yourself.
Accessories required
● Pre-fabricated cable with M12 and 7/8" connectors The patch cables are available in
different lengths.
● To produce your own cable:
– M12: PROFINET cable (4-wire, shielded) and M12 PROFINET connection plug
– 7/8": 5-wire patch cable with 7/8" connectors
