DPV1 Class 1 Messaging (MS1)
The user can exchange DPV1 Class 1 data with a configured field device using the
configured Modbus Registers. The user will need to assign Slot and Index
combinations to Modbus Holding Register Addresses (see below).

– DPV1 Objects Holding Register address
Once the PROFIBUS Master reads or writes to a DPV1 Class 1 Slot/Index, the
PLX51-PBM will use the data located at the configured Modbus Address.
NOTE: If the PLX51-PBM has been setup as a Modbus Master then the data will be read or written to
the specific Modbus HR address in the target device when the DPV1 Message request is received on
the PROFIBUS network.
