7 Operating the MC100
7.1 Process Data Exchange (Cyclic data)
The cyclic data consists of control bits and status bits.
There is a distinction between MC100 control/status bits and pumps control/status bits.
When connected to the Fieldbus network the MC100 will always transmit and receive 1 word for the
MC100 function and minimum 1 word for the pumps (even if only 1 pump is connected there will still
be allocated 1 word, where the highest 8 bits will be empty).
7.1.1 Process control bits for MC100
There is allocated one word (2 bytes) for MC100 control bits as shown below.
