WAGO-I/O-SYSTEM 750
ETHERNET TCP/IP
10Base-T, 100BaseTX
Either the 10BaseT standard or 100BaseTX can be used for the WAGO
ETHERNET fieldbus node.
The network architecture is very easy and inexpensive to assemble with S-
UTP cable as transmission medium or with cables of STP type.
Both types of cable can be obtained from any computer dealer.
S-UTP cable (screened unshielded twisted pair) is single-shielded cable of
Category 5 with overall shield surrounding all twisted unshielded conductor
pairs and an impedance of 100 ohm.
STP cable (shielded twisted pair) is cable of Category 5 with stranded and
individually shielded conductor pairs; no overall shield is provided.
Wiring of the fieldbus nodes
Maybe, a crossover cable is required for direct connection of a fieldbus node
to the network card of the PC.
Fig. 4-2: Direct Connection of a Node with Crossover Cable
If several fieldbus nodes are to be connected to a network card, the fieldbus
nodes can be connected via an ETHERNET switch or hub with straight
through/parallel cables.
