SIS maintenance system


When safety critical functions (SIL safeguards and/or process safety interlocks) are applied within a process facility, it is needed that these safety functions are properly maintained. A maintenance management system is needed (also described in IEC 61511). For example to plan periodical calibrations and proof tests. The maintenance engineer may write down the test results in a book or Word document. A more sophisticated system may be developed (e.g. using SAP). But the SIS maintenance management system of Consiltant BV can be used as well.
