Analog Input Functional Block

The Analog Input Functional Block

The Analog Input functional block measures the voltage, current, or resistance
of a hardware transducer. This value is then translated into an appropriate
value to send on the Analog output network variable. For example, a
temperature transducer might return a value of 10,000 to 15,000 ohms. The
Analog Input functional block translates this raw value into the appropriate
temperature value using a translation table. The following figure and table
summarizes the output of the Analog Input functional block:
