Could you please clarify what the difference between Online/Offline options provided for Sensor and Final Element in exSILentia, in regards to Proof Test Interval. There is no such option provided for logic solver part! In case of choosing "Offline" optio

Offline/Online for proof testing refers to if you perform your proof test while the process is running (online) or while the process is shutdown (offline). If the process is offline, it is assumed that the SIF does not need to provide any risk reduction and therefore the duration is irrelevant. If you bypass a SIF/subsystem, and the process is still online, you will impact the ability of the SIF to perform the safety function. In this case duration is relevant.
