The fieldbus coupler is comprised of:
•
Supply module which includes the internal system supply as well as power
jumper contacts for the field supply via I/O module assemblies.
•
Fieldbus interface with the bus connection RJ 45
•
Display elements (LED’s) for status display of the operation, the bus com-
munication, the operating voltages as well as for fault messages and diag-
nosis
•
Configuration Interface
•
Electronics for communication with the I/O modules (internal bus) and the
fieldbus interface
