System 182 XT-4 PROFIBUS connection
7 - 7 ba76027e01 02/2012
Transmitted sensor data The following data for a sensor is transmitted to the PROFIBUS master
as a consistent data block:
 Sensor number (Sxx)
 Sensor status
 Sensor model
 Status info of sensors
 Measuring mode
 Measured value status (main and secondary measured value)
 Main measured value
 Secondary measured value
Note
The transmitted data of all IQ S
ENSOR N ET sensors are available in the
YSI document, "IQ S ENSOR N ET sensors: Encoded data for field bus
communication" (ba76073e). It is regularly updated when new sensors
are introduced and when the sensor software is changed (if it concerns
the transmitted sensor data). The latest version is available on the
Internet, in the download area for operating manuals.
Note
Check the transmitted data for agreement of the requested and
transmitted sensor number (Sxx) before any further processing.
7.5.2 Sensor administration under PROFIBUS
Preparation of the IQ S ENSOR N ET for communication with the
PROFIBUS may require, e.g. the following:
 Creating an IQ S
ENSOR N ET system with specific assignment of
sensor numbers to sensors
 Creating several IQ S
ENSOR N ET systems with the identical
assignment of sensor numbers to sensors
 Changing the order of the sensors in an already installed system
