Dual-redundancy and Reliability
There is no single point of failure in Yokogawa’s FCS! The processor modules, power supplies, and I/O modules, including the communication bus, support a redundant configuration. The robustness of the FCS comes from this configuration known as “Pair and Spare” and the reliability of calculation results is guaranteed through real-time validation. Two processor modules have two MPUs each. MPU 1 and MPU 2 in the primary processor module are always comparing the calculation result, and if the results do not match, the first processor module goes into maintenance mode while the secondary processor module takes over process control. In order to make this switch over seamless, MPU 3 and MPU 4 are also calculating and comparing the results while the primary processor module is active. Pair and Spare is Yokogawa’s unique technology, supporting impressive levels of availability for CENTUM and ProSafe-RS. This architecture has been approved by TÜV Rheinland for safety instrumented systems. The ProSafe-RS certification was granted to Yokogawa in exceptionally short period of time, and it was due in-part to our Pair and Spare technology
pany.
