5 1 Task 2.1 Overview 1 Task Introduction The infrastructure of a discharge treatment plant comprises the two S7-300 substations Inspection Shaft and Stormwater Overflow. Both stations shall communicate with a central station cost-efficiently, as well as exchange data. TeleControl Server Basic V3 is installed on the central station PC. The internet based GPRS service should be used as a data transfer medium. Overview of the automation task The figure below provides an overview of the automation task. Figure 1-1 Central station TeleControl Server Basic INTERNET GPRS?? Inspection shaft Stormwater overflow Problem description This application example should meet the following requirements: Remote station 1 (inspection shaft) requests data cyclically from radio station 2 (stormwater overflow). Remote station 2 sends event-triggered data to remote station 1. Remote station 1 and 2 send important process variables cyclically to the central station. The central station monitors the status of the connected remote stations. Using visualization software, the simulated process shall be operated and controlled in the remote stations.

6 2 Solution 2.1 Overview 2 Solution 2.1 Overview Display The figure below shows a schematic overview of the most important components of the solution: Figure 2-1 Central station 1 TCSB DSL router INTERNET MSC300_ Library MSC300_ Library 2 3 Inspection shaft Stormwater overflow Setup The core of this application example is the TeleControl Server Basic V3 (TCSB) in the central station. The TCSB enables a direct connection as well as crosscommunication between the S7-300 controllers. The counterpart to the TCSB is the MD720 modem which is contained in each remote station. Table 2-1 No. Module Explanation 1. Central station The central station consists of a standard Windows PC/PG with integrated Ethernet interfaces. The PC is connected with a DSL router via the Ethernet interface. Installed on the PG/PC are STEP 7 V5.5, TeleControl Server Basic V3, OPC Scout V10, and WinCC flexible. 2. Inspection Shaft station Remote station Inspection Shaft consists of an S7-300 station (CPU PN/DP and CP 340) and an MD720 modem. CP 340 and MD720 are interconnected via the serial RS232C interfaces. Entry ID: , V1.0, 05/2015 6

7 2 Solution 2.2 Description of the core functionality No. Module Explanation 3. Stormwater Overflow station Remote station Stormwater Overflow consists of an S7-300 station (CPU PN/DP and CP 341) and an MD720 modem. CP 341 and MD720 are interconnected via the serial RS232C interfaces. Advantages The solution presented here, offers you the following advantages TeleControl Server Basic V3 enables economic data communication between all remote stations, or between remote and central station respectively. S7-300 stations can be integrated into the TCSB environment. The core application areas are industrial applications where data shall be sent in a cost-efficient way, such as in waste water treatment plants, for water purification, or in pump stations. The OPC interfaces of TCSB provide the data of the connected stations to one or several connected OPC clients. GPRS and INTERNET secure short transmission times. Optimized energy demand and minimized data volume. Delimitation This application example does not contain a description of: SIMATIC NET MODEM MD720. Please refer to document \4\. SIMATIC NET TeleControl server Basic. Please refer to document \3\. SIMATIC HMI operator panels the LAD/ FBD/ STL/ SCL programming languages. Basic knowledge of these topics is assumed. Note The MSC300_Library library can only be used for S7-300 controllers. Cross-communication with stations that do not use a WDC protocol (for example, S stations) is not possible. 2.2 Description of the core functionality Realized functions The following core functions have been realized in the application example: MODEM MD720 is initialized and the GPRS connection between remote station and central station is established. Station Inspection Shaft requests data from the Stormwater Overflow station in a fixed time interval (polling). The Stormwater Overflow station responds with the requested data. Station Inspection Shaft sends data to TeleControl Server Basic in the central station in a fixed time interval. Entry ID: , V1.0, 05/2015 7

8 2 Solution 2.3 Overview and description of the user interface Station Stormwater Overflow sends data to the TeleControl server in the central station in a fixed time interval.
