This device profile is dedicated to analog transducers that may also provide digital I/O capability. Additionally, the profile describes closed-loop controllers that collect sensor signals and provide set values for actuators. Devices compliant to CiA 404 may support up to 199 transducer channels. The analog input function distinguishes between field value and process value. Field values are non-scaled readings from the analog/digital converter, counting from the incremental encoder, or calibrated electrical values provided by a transformer. This value is converted to the physical dimension or the measured quality, and the result is called process value. Examples for process values are a value in kg for weight measurement, a value in °C for temperature measurement, or a value in mm for displacement measurement. The transducer parameters are given in selectable resolutions (8-bit, 16-bit, and 32-bit integer, or Real32).
