Sequence of addressing Description
1. I/O diagnostic interface
1)
Can be activated by DIL switch. When activated, it will occupy
the first 16 inputs and outputs in the address range.
2. Analogue modules Modules with analogue inputs/outputs
3. Technology module e.g. CP interface, front−end controller CPX−FEC
4. Digital modules Modules with digital inputs/outputs
1)
In exceptional cases this address range can also be occupied by status bits (see Tab.1/3).
