2.1.2 Data exchange with the PROFIB US-DP fieldbus protocol
The fieldbus protocol PROFI BUS-DP uses a communication
profile to regulate how data is exchanged among the fieldbus
stations. Cyclical and acyclic data exchange are differentiated
thereby.
2.1.3 Brief overview of the function range
– General communication and diagnostic messages about
cyclical/synchronous data exchange (DPV0)
– Acyclic/asynchronous data exchange (DPV1)
–Diagnostics
–ProcessData
2.1.4 Control c ommands
The operating modes FRE E ZE, SYNC and CLEAR_DATA are
suppor ted by the bus node in accordance with the PROFIB-
US-DP standard.
The method of accessing these commands depends on the
