Emerson DeltaV DCS with Profinet

Click2Contact

Emerson Process Management, working with MYNAH Technologies, has expanded customers’ network possibilities and application options by adding Profinet capabilities to the DeltaV distributed control system (DCS).

The addition of Profinet saves DeltaV users time and effort by enabling direct connection between the DeltaV DCS and plant floor devices such as motor control centres, variable speed drives and PLCs in process automation businesses. Users no longer need to use a protocol converter to connect to the system.

Profinet joins a wide range of DeltaV ethernet-based protocols, such as Modbus/TCP and Ethernet/IP. The capability is easily added to the system via both M-series and S-series Virtual I/O Module 2 (VIM2) interfaces.

The Profinet driver supports simplex VIM2 modules deployed with commercial off-the-shelf (COTS) network equipment. For enhanced reliability and availability, simplex VIM2 modules can be deployed with an external switch that handles media redundancy network topology via Media Redundancy Protocol (MRP) and also behaves as the ring master.

Saving time and increasing safety, the VIM2 interface and firewall function allow a high level of access without sacrificing control system security and integrity. The VIM2-based Profinet architecture enables users to optimise expansion activities or perform maintenance operations on applications in remote locations using a laptop with vendor-specific diagnostic tools — all while constantly monitoring applications from a centralised network.
