Monitoring of Remote Measuring Points using an RTU3030C and TeleControl Server Basic V3.1

  • Entry
  • Associated product(s)
The battery-powered SIMATIC RTU3030C monitor processes in remote plants. The RTUs log into the cellular network at configured time intervals and transmit current data to the TeleControl Server Basic in your control center. In order to display the data, you can use any OPC UA client. Optionally, the communication can be secured via a VPN tunnel.

Functionality of the application example
Using an analog level sensor, the RTU monitors the fill level of a rainwater overflow tank. The measurement is enabled with a digital humidity sensor. In addition, a digital level sensor (float) is installed that is enabled when a critical fill level is exceeded.

At configurable intervals, the RTU switches from the sleep mode to the update mode in order to read out the inputs and to edit the program. Subsequently the RTU transfers the current data to the TeleControl Server Basic (TCSB).

In order to read the TCSB data, UaExpert is connected as an OPC UA client.

Variants
This application example is available in two variants:

  1. Unsecured communication between RTU3030C and TeleControl Server Basic V3.1. 



  2. Secured communication through a VPN tunnel between RTU3030C and TeleControl Server Basic V3.1.



Customer benefits
  • Configuration sample for connecting a RTU to the TeleControl Server Basic V3.1.
  • Power saving configuration of the RTU.
  • Secured Communication over a VPN-tunnel with SINEMA Remote Connect Server.
  • Read the processing values over OPC UA.
