Secondary measured value The transmitted data of all IQ S sensors is given ENSOR in the WTW document, "IQ S sensors: encoded ENSOR data for field bus communication" (ba75560de). It is con- stantly updated with the appearance of new sensors and changes to the sensor software (insofar as they affect the transferred sensor data).
Interface for the PROFIBUS MIQ/2-PR Before further processing check the sent data for agree- ment of the requested and sent sensor number (Sxx). 3.6.2 Sensor administration under PROFIBUS Preparation of the IQ S for communication with the PROFI- ENSOR BUS may require, e.g. the following: ...
