7.4 Transmitted sensor data

7.4.1 Overview

Data transmission is carried out via the RS 485 interface with the
Modbus RTU protocol.
The following data for a sensor is transmitted to the Modbus 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
document, "IQ S
ENSOR
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.
The datasets of the sensors are made available to the Modbus master
in a sensor datablock in the DIQ/S 182-MOD.
