Information:
− B = Statistical information (in-service monitoring) , T = Tests (out-of-service diagnostics)
− Tests highlighted in red border require an initialization with reference test
− Tests highlighted in gray can optimize the proper functioning of safety equipment according to IEC61508 and IEC61511,
provided these tests are performed regularly.
