Data Format

All configuration parameters and data are transmitted in Little Endian format.
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.
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.
