Siemens enhances TeleControl Server Basic software for cellphones

November 25, 2014 - Siemens expanded TeleControl Server Basic software Version 3 to include numerous functions for even greater flexibility, reliability and security. The version makes it possible to monitor and control remote stations around the world not only using a cell phone, but also via Ethernet/Internet. This enables plant operators to gradually increase the number of connected systems. The integrated Teleservice Gateway permits the diagnosis of remote stations from any PC with Internet access. The servers can be operated redundantly to increase plant availability. The standard OPC UA interface that is additionally supported in Version 3 offers users new functions for optimizing data availability and archiving. Extended tunnel mechanisms increase security during data transfer. The software is suitable for widely distributed plants, for example, in water treatment, power distribution or traffic monitoring.

TeleControl Server Basic helps to monitor and control geographically distributed systems from one control center (remote control). The controllers of the connected remote terminal units (RTUs) are directly linked to the cell phone network by communications processors. The new version also offers the option of connecting RTUs to the wide area network (Internet) on the basis of the modular Simatic S7-1200 controller via the CP 1243-1 communications processor and external industrial routers (e.g. Scalance M). The control center software supports up to 5,000 Simatic S7-1200, Simatic S7-200 or S7-300 controllers. Plant operators can gradually increase the number of remote terminal units by using software packages called Powerpacks and thus adapt flexibly to rising demand.

For access by HMI (Human Machine Interface) or SCADA (Supervisory Control and Data Acquisition) programs, Version 3 now supports the OPC UA interface in addition to OPC DCOM. Integrated OPC UA functions help to optimize data archiving and availability. This enables the process data to be buffered in the TeleControl Server Basic in the event of short interruptions and then transferred back again seamlessly. To boost plant and process data availability, users can also operate the servers redundantly with the new version. Extended tunnel mechanisms ensure even greater data security during communication across public networks.

TeleControl Server Basic offers extensive diagnostic functions that range from the checking of temporary GPRS connections to the PLC status of all remote stations. Users can monitor the Simatic S7-1200 stations with the Simatic Step 7 engineering system from any PC with Internet access, even in the case of dynamic IP addresses. Thanks to the "wake-up function", the RTUs do not have to be permanently online. If necessary, however, the RTU is reactivated by a text message and an Internet connection is set up between control center and remote unit. In this way, operators can interconnect globally distributed systems with low data volumes and using low-cost standard cell phone contracts. And because billing is based on data volume rather than connection time, operating costs can easily be calculated.

TeleControl Server Basic is particularly suitable for distributed systems such as those used in wastewater treatment plants, district heating networks and pumping stations. Other important areas of application include energy distribution, traffic control, and oil and gas supply grids.
