The Fieldbus Controller consists of:
•
Device supply with internal system supply module for the system supply as
well as power jumper contacts for the field supply via assembled I/O
modules
•
Fieldbus interface with the bus connection
•
Display Elements (LED's) for operation status, diagnostics, and
communication status
•
Configuration and programming interface port
•
Operating mode switch
•
Electronics for communication with the I/O modules (internal bus) and the
