Wiring
Ethernet Wiring Industrial standard cables can be subjected to extreme mechanical stresses. The
minimum for SafeEthernet protocol communication requires Category 5 twisted pair
cable with a class D rating, for greater distances and less possibility for errors
occurring, fiber optic cable should be used.
The controllers communicate at 100 Mbit/s (Fast Ethernet) and 10 Mbit/s during full
duplex mode. The XPSMF2DO801 safety remote output device has an auto "cross-
over" function built into the switch, which allows the use of both a 1:1 cable and a
cross-over cable.
The outer shielding of the twisted pair cable must be earthed at both ends. If an
RJ 45 connector is used, it automatically connects the cable's shield to the
controller’s housing.
Interface
Elements
When connecting a module or a PLC over Ethernet communication, the following
interface elements are recommended: FL CAT5 TERMINAL BOX of Phoenix
Contact
(R)
. The controllers are mounted on an earthed EN mounting rail. The
conductors of the field cable are attached to the interface terminals. It is important
to make sure that the cable shield is also connected via the strain relief.
Prefabricated patch cables are used to connect the interface element and the
XPSMF2DO801 safety remote output device. If the rail is earthed in accordance with
the standards, it is enough to mount an interface element on a rail.
