6 Communication with the PLC

The fieldbus interface contained in the R1000 enables the communication with a fieldbus master.
The well-defined data structure of the R1000 enables the use of the cyclical communication data
transmission mode.
The R1000 has a four line display. The additional 2 lines, as compared to the previous regular
version, are used for fieldbus specific messages.
