What are the functions of SIS?
SIS stands for Safety Instrumented System, which is an important component of production automation systems. Depending on the application and environment in which it is used, it can be categorized into FGS, MAS, PAS, etc. If DCS process control is the norm, then SIS can be considered the exception (equivalent to positive logic and negative logic). Its function is to ensure safe operation at the site and prevent equipment damage and casualties; the specific way in which this is achieved depends on the interlocking logic relationships defined in the configuration. You can take a look at the I/O table of the SIS system for the project, as well as the logic diagram of the connections. Now I know the role he plays in the project. As for more details, you can learn more about them.
