Difference Between Availability Reliability Sil Instrumentation Tools Availability is different from reliability in that it takes repair time into account. an item of equipment may not be very reliable, but if it can be repaired quickly when it fails, its availability could be high. In the fields of industrial automation, engineering, and functional safety, three concepts often arise: availability, reliability, and safety integrity level (sil). although they are related to system performance and safety, their definitions, evaluation methods, and applications are distinct.

Availability takes repair time into account and is defined as the proportion of time an item can perform its function. sil refers to the safety level required of a system and describes the safety reliability needed, not the overall reliability. Availability is different from reliability in that it takes repair time into account. an item of equipment may not be very reliable, but if it can be repaired quickly when it fails, its availability could be high. All of them relate in some way to how well something will perform in a particular task; however it is important to use the correct term for the task in hand, otherwise you are likely to end up with the right answer but to the wrong question!.

Learn the difference between availability and reliability and how each affect downtime, productivity, and long term asset performance. Learn the difference between sis, sif, and sil with this complete functional safety guide based on iec 61508 61511. includes architectures, sil levels, and engineering best practices. The primary reason that time and component reliability has confused designers is because iso13849 1 and iec62061 cover a broad range of technologies and use different terms to describe the aspects of time in the pl and sil calculations. Iec 61508 certified devices will have a designated sc level from sc1 to sc4 depending on the assessed sil level. this will be clearly shown on the sil certificate.
