Communication with the PLC
5.2.1 Fieldbus interface
5.2.2 Data transmission
The SND40 with integrated Fieldbus- interface can communicate with a Fieldbus-master. The data
transmission communication takes place in cyclic data exchange mode.
For each transmission direction 4 bytes are reserved.
The allocation of the control signals is described in the signal overview.
The timing behaviour of the control via the bus corresponds with the information provided in the
timing diagrams of the parallel interface.
