2 PROFIBUS GATEWAY MODULE (PGM) OVERVIEW
2.2 About DPV1 and HART enhancements for PGM
DPV1
PROFIBUS-DPV1 supports acyclic data communication between master and slaves for the standard functions
of PROFIBUS-DP. A Class1 master (PGM) controls the cyclic exchange of process data with the slaves. Using
the acyclic communication functions, (PROFIBUS-DPV1) PGM now supports acyclic data communication to
the slaves in addition to the cyclic process data.
Acyclic data transfer exists wherever slave devices provide several parameterization options during operation.
Typically, the parameters of a device such as limit values, rotational speed or torque, operation mode, generation
of an error list, and generating alarms, are parameterized during operation.
HART enhancements
PGM is enhanced to support HART over PROFIBUS profile. The PBHIOMB represents a HART IOM in RIO
slave and it is associated to a PDC in the DSB, which is connected to the Protocol block.
