1 Introduction
Use case
The RTU3041C uses an analog level sensor to monitor the level of a rain overflow
basin. A digital moisture sensor starts the measurement.
In addition, a digital level sensor (float) is installed, which is activated when a
critical level is exceeded.
At configurable, timed intervals, the RTU switches from sleep mode to update
mode to read the inputs and process the program.
The position determination and the time synchronization of the RTU3041C is done
via GPS.
Subsequently, the current data is sent to the TeleControl Server Basic (TCSB).
To read out the data of the TCSB, UaExpert is used as OPC UA Client.
Solution approach
•
An application program with the program blocks "Send email" and "Send SMS"
implements the sending of emails and SMS messages.
•
The position determination is done with the "GPS position" block. The block
checks whether the RTU is moving outside the specified range.
•
The RTU3041C is configured via the Web-Based Management (WBM) of the
RTU.
•
The blocks are graphically displayed and programmed via the Web-Based
Management (WBM) of the RTU3041C.
