Fig. 3-1: Fieldbus ECO-Coupler 750-343 PROFIBUS DP g034300e

The Fieldbus Coupler comprises of:

· Supply module with internal system supply module for the system supply.

· Fieldbus interface with the bus connection

· DIP switch for the node address (binary)

· Display elements (LED's) for status display of the operation, the bus

communication, the operating voltages as well as for fault messages and

diagnostics

· Configuration Interface

· Electronics for communication with the I/O modules (internal bus) and the

fieldbus interface
