PROFIBUS

3.1.3 Operating System

Once the node is configured in the software, the node address is set and the

node is wired properly, the power can be applied.

After switching on the supply voltage, the coupler performs a self-test of all of

the device functions, the I/O module and the fieldbus interface. If the power

supply is working correctly the I/O-LED is green. Following this the I/O

modules and the present configuration is determined, whereby an internal list

is generated. This list includes an input and an output area on which is

represented the fieldbus RAM of the protocol chip.

In the event of a fault the Coupler changes to the "Stop" condition. The

I/O-LED flashes red. After a fault free start up the Coupler changes to the

"Fieldbus start" status.
