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

Preparation of the IQ S
ENSOR
N
ET
for communication with the PROFI
-
BUS may require, e.g. the following:

Creating an IQ S
ENSOR
N
ET
system with specific assignment of sen
-
sor numbers to sensors

Creating several IQ S
ENSOR
N
ET
systems with the identical assign
-
ment of sensor numbers to sensors

Changing the order of the sensors in an already installed system
The transmitted data of all IQ S
ENSOR
N
ET
sensors is given
in the WTW document, "IQ S
ENSOR
N
ET
sensors: encoded
data for field bus communication" (ba75560de). It is perma
-
nently updated when new sensors are available and when
the sensor software is modified (if the modifications are rel
-
evant 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".
Check the transmitted data for agreement of the requested
and transmitted sensor number (Sxx) before any further
processing.
