APPENDIX 3. INPUT SELECTOR (IS) 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 quanti-
ties to be transmitted to the controller as a controlled variable. This feature is primarily used for temperature control
systems.
