Problems with interlocking control in SIS
Thread Content
In SIS, the interlock is activated due to unstable equipment. What do FALSE and TRUE mean in interlock control? I see FALSE and TRUE for interlock in the alarm summary. Please share your thoughts, thank you
One is an error message and the other is genuine information; you should post the SIS log file before conducting an analysis.
What do error messages and actual information mean?
Each issue needs to be analyzed on a case-by-case basis; I need to look at your record documents first.
0 and 1: 0 does not output a signal, 1 outputs a signal
Whether the coil corresponding to you is powered (TRUE) or de-energized (FALSE) is often related to the operation of the solenoid valve on site. Specifically, consider the interlock logic and the control scheme for on-site equipment.
Typical DCS systems set the interlock trigger value at \"1\" for activation, while SIS safety instrumented control systems use \"0\" for triggering. I assume you are referring to the action results shown on the interlock diagram; it’s necessary to check how it is specified at the lower level and then interpret it in conjunction with the logic diagram!
