Micro Automation: Wireless Data Communication based on GPRS (flexible) - MAS 31
The SIMATIC S7-200 components used in this application example are currently phased out.
This application can be realized as easily and quickly with the new SIMATIC S7-1200. The respective application example with SIMATIC S7-1200 is available here: 39863979
Furthermore, many useful applications with SIMATIC S7-1200 are available here: 35923253
The infrastructure of a discharge treatment plant contains the “Stormwater Overflow” substation. It is supposed to communicate with a control center. The internet based GPRS service, which charges by data volume, should be used as a data transfer medium. The control center should enable central operator control and monitoring.
The automation solution uses the SINAUT Micro SC remote control system with the GPRS modem MD720-3 to visualize process data from the Remote Station via the Central Station.
Remote Station “Stormwater Overflow”
The S7-200 CPU 222 controls pump “P1”, which automatically pumps the water of the stormwater overflow structure into the water treatment plant. Pump “P2” which can be operated manually via the Central Station enables pumping the water into a nearby river. All process data are transferred to the Central Station via the GPRS modem MD720-3.
The OPC server SINAUT MICRO SC is used as a platform for data exchange with the Remote Station. The Central Station communicates with the GPRS station via an Internet connection. As OPC client, WinCC flexible enables visualizing and operating the process.
Advantages against Micro Automation Set 21
- Use all S7-200 CPU's (CPU221 - CPU226)
- Variable interface selection (Port 0 oder Port 1) for connection between modem and CPU
- More memory space for the user program due to the small size of the block library
For the startup we offer you software examples with test code and test parameters as download. The software examples support you during the first steps and tests with your Micro Automation Sets. They enable quick testing of the hardware and software interfaces between the products described in the Micro Automation Sets.
