Hello Vijay; Siemens does not provide a TMR or QMR (Quadruple Modular Redundancy) system, that relies on increasing levels of hardware for security purposes. Rather it proposes an alternative based on FMR (Flexible Modular Redundancy) that implements the same SIL or PEL levels of safety using software configurations. Our member Gunner proposes a very informative presentation on that subject in the following discussion. You should also spend some time on the fine analysis provided by our friend H-H in the same thread: How Siemens Safety Systems FMR Architecture Competing with TMR Systems! Hope this helps, Daniel Chartier |
