Default assignment of the inputs and outputs to the process image

Once it has been switched on, the Bus Coupler finds out how many Bus Terminals are inserted, and creates
an assignment list. The analog and digital channels, divided into inputs and outputs, are assembled into
separate parts of this list. The assignment starts on the left next to the Bus Coupler. The software in the Bus
Coupler collects consecutively the individual entries for each of the channels in order to create the
assignment list counting from left to right. Four groups are distinguished in the assignment:

Group

Functional type of the channel

Assignment

1

analog outputs

byte-wise

2

digital outputs

bit-wise

3

analog inputs

byte-wise

4

digital inputs

bit-wise

All complex Bus Terminals are represented by analog inputs or outputs.
