内容预览：描述： GSM/GPRS 调制解调器 SINAUT MD720-3 将可以连接到 SIMATIC S7-1200 控制器。通过调制解调器，可与其它远程站和控制中心交换过程数据。在控制中心安装有路由软件 SINAUT Micro SC，该软件带有内置 OPC 服务器。通过将 WinCC flexible 作为 OPC 客户机实现本地可视化。 ......

An automation infrastructure contains RTUs with S7-1200 which shall communicate cost-effectively with a central station via the mobile communications network or via Ethernet.

This application examples constists of two application scenarios:

Secure connection of an RTU with CP 1243-7 LTE to TeleControl ServerBasic
Data Communication of S7-1200 Stations with TeleControl Server Basic V3.1

The documenation and the associated project are provided for each application scenario.

Secure connection of an RTU with CP 1243-7 LTE to TeleControl ServerBasic

The infrastructure of a water treatment plant contains an RTU (Remote Terminal Unit) with S7-1200 and CP 1243-7 LTE to securely transmit encrypted process data over the mobile radio network to the control station.The RTU establishes an OpenVPN connection to SINEMA Remote Connect Server. The RTU communicates with TeleControl Server Basic via this OpenVPN connection and transmits process data over the TeleControl Basic protocol.

Data Communication of S7-1200 Stations with TeleControl Server Basic V3.1

The infrastructure of a discharge treatment plant comprises two S7-1200 substations. The TeleControl Server Basic V3.1 in the central station enables a direct connection to both stations. Station 1 is connected to the TeleControl Server Basic V3.1 by means of the CP 1242-7 V2 GPRS via the mobile communications network. Station 2 is directly connected to the TeleControl Server Basic V3.1 by means of the CP 1243-1 via cable-based Ethernet. WinCC Advanced, WinCC Professional and WinCC V7 can be used as OPC UA client for visualization and control of process data.

Advantages

TeleControl Server Basic V3.1 enables economic data communication between substations and the central station.
The data of the connected stations are available for any OPC UA client via the OPC UA interface of the TCSB.
LTE, GPRS and internet: Always-on functionality.
In case of a connection failure, the CPs buffer the data and transmit the bundled data to the TeleControl Server upon reconnection.
If there is a brief interruption on the connection between the OPC UA client and the TCSB OPC UA server, the data remains available in the data buffer. Once the connection has been re-established, all values that have not been transferred will be sent to the OPC UA client.
