Specific IEC 61508 SIL Support

Safety Integrity Level (SIL)-as defined by the IEC 61508 standard-is one of the four levels (SIL1-SIL4) corresponding to the range of a given safety function's target likelihood of dangerous failures. Each safety function in a safety-related system needs to have appropriate safety integrity level assigned. According to IEC 61508, the safety integrity level for a given function is evaluated based on either the average probability of failure to perform its design function on demand (for a low demand mode of operation) or on the probability of a dangerous failure per hour (for a high demand or continuous mode of operation). The IEC 61508 standard specifies the requirements for achieving each safety integrity level. These requirements are more rigorous at higher levels of safety integrity in order to achieve the required lower likelihood of dangerous failures.
