Emerson Process Management, working with Mynah Technologies, adds Profinet protocol abilities to the DeltaV distributed control system (DCS). Profinet enables direct connection between the DeltaV DCS and plant floor devices such as motor control centers, variable speed drives and PLCs. With Profinet, users do not need to use a protocol converter to connect to the system. Other DeltaV Ethernet-based protocols include Modbus/TCP and Ethernet/IP. The new capability is 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 standard commercial off-the-shelf (COTS) network equipment. 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. The VIM2 interface and firewall function allow a high level of access without sacrificing control system security and integrity, according to Emerson. The VIM2-based Profinet architecture enables users to optimize expansion activities or perform maintenance operations on applications in remote locations using a laptop with vendor-specific diagnostic tools while monitoring applications from a centralized network.
