5.4 Acyclic data
The access on the acyclic parameters is possible by means of the DPV1 services MSAC1 and
MSAC2. The used data types are conform to the PROFIBUS-PA definitions.
A detailed listing of the overall acyclic data model is not given here, because the access out of the
PLC or DCS system is either done via a DDL (Device Description Language) or a DTM (Device
Type Manager).
DDL or DTM can be downloaded from the DREHMO homepage or can be ordered free of charge
via the DREHMO service.
