Communications module for safety, security

Staff -- Control Engineering, 11/1/2005

Tricon Communications Module (TCM) is said to offer open and flexible communications integration between safety instrumented systems (SIS) and distributed control systems (DCS) without compromising either safety or security. TCM incorporates an embedded OPC server and Modbus TCP/IP with safe peer-to-peer and other standard Triconex features. It supports full TCP/IP and routing functions for use with LANs and WANs. TCM reportedly acts as a layer that isolates Tricon safety system from control network and private LAN nuisances. Support for redundant connections helps ensure that there will be no "loss of view" of the safety system from the DCS. It is TÜV approved for use in systems to SIL 3. www.triconex.com Triconex, Invensys Process Systems
