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 is given in the YSI
document, "IQ S
ENSOR
N
ET
sensors: coded data for field bus
communication" (ba76073e). It is permanently updated when new
sensors are available and when the sensor software is modified (if the
modifications are relevant for the transmitted sensor data). The latest
version is available on the Internet.
Note
Check the transmitted data for agreement of the requested and
transmitted sensor number (Sxx) before any further processing.

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
