An input and an output would be considered exter nal functions where the PID calculation would be an internal function Information flows from an input function to an internal function to an output function when the controller is properly configured A single ST control can carry out several functions at the same time For instance closed loop control monitoring for several different alarm situations while at the same time operating switched devices such as lights and motors Each process needs to be thought out carefully and the controller s various functions set up properly Inputs Functions The inputs provide the information that any given programmed procedure can act upon In a simple form this information may come from an operator pushing a button or as part of a more complex procedure it may represent a remote set point being received from another controller Each analog input typically uses a thermocouple or RTD to read the temperature of something It can also read volts current or resistance allowing it to use various devices to read humidity air pressure operator inputs and others values The settings in the Analog Input Menu Setup Page for each analog input must be configured to match the device connected to that input Each digital input reads whether a device is ac tive or inactive controller with digital input output DIO hardware includes two sets of terminals each Each DIO must be configured to function a
