Potential relationships
8.2.1
General
The potential relationship of a Ethernet system realized with XI/ON modules is characterized
by the following:
• The system supply of gateway and I/O-modules as well as the field supply are realized via
one power feed at the gateway.
• All XI/ON modules (gateway, power feeding and I/O-modules), are connected capacitively
via base modules to the mounting rails.
The block diagram shows the arrangement of a typical XI/ON station with the gateway
XNE-GWBR-2ETH-MB.
