Failsafe controller gateway

Siemens has developed the Gateway CM104 TSAA, a migration solution for integrating Triconex failsafe controllers into Simatic PCS 7-based control systems. The Gateway enables existing systems to be expanded or modernised inexpensively and step by step.

Until recently, failsafe controllers have often been installed and operated separately from the process control system. That meant that they were frequently overlooked when it came to modernisation.

Siemens has developed the Gateway CM104 TSAA to bring both the process control system and the safety engineering up to the state-of-the-art standard at the same time. It facilitates continuous communication between the Triconex, Trident or Tricon failsafe controller and the Siemens automation system.

The gateway is integrated into the PCS 7 and can be laid out as a single or fully redundant link between the systems. It uses the Triconex TSAA protocol for this purpose, is based on standard industrial ethernet components and also contains diagnostic functions with alarms visualised in PCS 7.

The Siemens Gateway is used in the modernisation and migration to PCS 7 to form a link with existing Triconex failsafe products. It can also be used in projects requiring communication to PCS 7 controllers. The engineering is carried out with the aid of standard PCS 7 or STEP 7, enabling existing systems to be expanded or modernised inexpensively, step by step with Simatic.
