"SafetyNet is a comprehensive solution for safety related applications, said MOST VP of Marketing Dave Reynolds. It provides a SIL 2 level solution to customers working in BMS or ESD applications without requiring the use of redundant I/O or redundant controllers. SafetyNet provides a very cost effective SIL 2 solution, while redundant controllers can always be added to the system to provide greater system availability at a later date.
SafetyNet is built on the same control platform as the MOST Process Automation System, enabling users to address process control and functional safety needs with the same control platform. A single SafetyNet Workbench can be used to develop both process control and functional safety applications, according to Reynolds. Static analysis tools are provided to assist in the verification and validation of the safety strategy..
With a single platform and software workbench, MOST can provide solutions for process, discrete and functional safety applications, reducing your needs for spares, training and support and providing you with considerable savings. The SafetyNet product line was first announced last year.
"SIL 2 systems are meeting a growing number of safety system requirements in process plants as users are trying to reduce the hazards in their plants to acceptable levels," Reynolds explained. "Many companies have determined that if an operation requires a SIL 3 rating, then it is too hazardous and needs to be redesigned. After working to reduce the risks in their plants to SIL 2 or lower, customers are then looking to optimize their investments in safety related systems with the appropriate level of risk reduction. In these applications, a SIL 2 safety system provides a very cost effective solution."
