System 182 PROFIBUS connection
7 - 7 ba75503e07 04/2012
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 is given in the WTW
document, "IQ S
ENSOR
N
ET
sensors: coded data for field bus
communication" (ba75560de). 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, in the download area for operating
manuals. Use the search function for the download and search for
"ba75560de".
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
