Configuration of Profibus Field Devices

Using vendor-supplied Profibus DTMs, users are able to remotely:

• Configure Profibus devices associated with the DTM

• Adjust the parameters of these devices while they are off-line

• Adjust the parameters of these devices while they are on-line

PRM Master Bus Module and its DTMs

Control Expert uses a Profibus Remote Master (PRM) Gateway module (the bus master physical device) and its PRM configuration tools (software):

• The PRM Master DTM that allows the PRM Gateway to carry out:

  • Explicit DPV0 functions (control and diagnostics of the Profibus slaves on the network).

  • Communication functions (implicit DPV1 exchanges with the Profibus slaves). It also provides access to the Profibus slaves from the Control network to HMI, SCADA or ASSET management tools.

• The PRM Comm DTM that only allows the PRM Gateway module to carry out communication of implicit DPV1 exchanges and access to management tools.

The Modbus TCP I/O scanning link between the PLC and the (PRM) Gateway module connected to the Profibus network is provided by a Quantum, Premium, M340, or M580 module with an Ethernet port.
