IF2030/ENETIP
5.3 Data Format
All configuration parameters and data are transmitted in Little Endian format.
Sensors/controllers with RS422: cyclical data are decoded, i.e., a 4th byte is added to the 3 bytes and then
transmitted. The sensor signals selected for transfer and their sequence are available on the sensor’s web
interface.

Fig. 12 Interpretation of RS422 sensor data in IF2030/ENETIP
Sensors/controllers with RS485: cyclical data are transmitted via the fieldbus without change, i.e., as a
binary block as described and supplied by the sensor. Please refer to the sensor’s operating instructions for
the data set structure.
