The Rheonics SME provides clients PROFINET interface to get digital data on devices ordered with
Profinet connectivity. This document provides guidance for field connection by an end user.
Note: If your sensor was ordered without Profinet, it is possible to upgrade it to add profinet
remotely. Contact Rheonics Sales team to order.

8.3 How to read sensor status?
Sensor status is a WORD data type, these status bits can be used over digital communication
channels to understand when the sensor is operating correctly and when there is an issue.
Figure 20. Sensor Status parameter table.
In the scenario described in Figure 20, Sensor Status has a value 16#1701, bytes must be
swapped for the correct reading of the sensor as they should be read as 16#0117 for a little-
endian format. Sensor error status is the combination from any bit from Table 2. Sensor error
status bit code and description.in this scenario Error0117 is the combination (OR) of the error
bits.:
Bit
