For many plant operators, the continual pressure to improve operations while reducing downtime is partly solved by the use of function blocks for PLC programming. “Function blocks give you time ...

That’s why it’s often used for PID loops. There are also several safety systems that use Function Blocks as their programming method, he added. The main takeaway when looking at the different PLC ...

a more structured programming approach is taken with the use of “tags,” which are stored within the PLC’s memory in a tag database. With a Tag Database, all function blocks, including contacts, coils, ...
