Data exchange between fieldbus and PLC
Fieldbus
I/O data As an option, we offer fieldbus interfaces for the controllere, e.g. Profibus DP,
DeviceNet, Ethernet, etc.
Data exchange via fieldbus is possible between the PLC in the controllere and the
fieldbus master (

figure below).
Description of the corresponding fieldbus: → separate supplementary device man-

Configuration data (CDI) of the slaves
The configuration data for standard, A and B slaves are each stored in one data
word. The structure is shown below and is the same for all slaves.
The slave profile has the following structure:

4 digital inputs, 2 digital outputs
AS-i profile = S-7.A.E
this results in the following configuration data of the slave:
1110 = 0Eh 0111 = 07h 1010 = 0Ah 0111 = 07h
Current and projected configuration data are distinguished. The addresses for
these data are as follows.
