17. IS Function Block
The function of the Input Selector (IS) block is to automatically select one signal from multiple input signals
using a specified selection method.
The IS block is used for selective control in which one measured quantity is selected from multiple measured
quantities to be transmitted to the controller as a controlled variable. This feature is primarily used for
temperature control systems.
