Industrial plants or plants in public infrastructure areas are often spread across wide areas, sometimes even across national borders. The range of telecontrol products offers complete solutions.
Industrial plants or plants in public infrastructure areas are often spread across wide areas, sometimes even across national borders. The range of telecontrol products offers complete solutions with the following features:
TeleControl Basic is a simple remote control and remote maintenance system optimized for the use of public communication networks such as mobile wireless and internet for connection to the substations.
It comprises the TeleControl Server Basic control center software and substations of the type SIMATIC S7-1200, ET 200SP and RTU3000C. In addition to communication between the control center and the substations, the system also enables internode communication between substations.
Small-scale applications with few outstations can be implemented, as well as large-scale plants comprising up to 5000 outstations.
TeleControl Professional includes telecontrol systems for extensive, expanded applications of the process industry. From SIMATIC PCS 7, SIMATIC WinCC or non-Siemens control systems using OPC, outstations based on SIMATIC S7-1500, ET 200SP, S7-1200, S7-300/400 and RTU3000C can be monitored and controlled. The outstations and substations can communicate with each other as well as with one or more control centers. TeleControl Professional has a modular design throughout and can be used with extreme flexibility.
Both telecontrol systems can be connected to a non-Siemens control center system (OPC client) via OPC.
Sample configuration: TeleControl Professional
TeleControl Professional is a telecontrol system based on SIMATIC S7 for the fully automatic monitoring and control of remote control stations which exchange data with one or more control centers, or with each other, via a wide range of WAN media.
TeleControl Professional facilitates an integrated communications concept (TIA) and complete integration into the SIMATIC environment. The modular design and the support of a huge variety of network forms and operating modes including IP-based networks permit the design of flexible network structures that can also contain redundant links.
By using all forms of transmission media (e.g. dedicated line, wireless, dial-up networks, mobile wireless, DSL), the networks can be optimally adapted to the respective local conditions.
The system also supports data exchange with devices of the previous system SINAUT ST1 (based on SIMATIC S5).
The TeleControl Professional system has proven itself in the smallest plants with only a few process stations, but also in complex networks with many hundreds of stations.
Examples of the range of uses:
The TeleControl Professional system is based on the SIMATIC systems S7-1500, ET 200SP, S7-1200, S7-300, S7-400, the RTU3000C family and on WinCC/PCS 7. It supplements these systems with the special communications processors for S7-1200 and SINAUT components listed below, comprising hardware as well as software.
The telecontrol components support the set-up of complete hierarchical communication networks comprising terminals, node stations and control center.
For the exchange of information between the individual devices, conventional WANs can be used, such as dedicated-line, wireless and dialup networks as well as IP-based WANs such as DSL, GPRS, UMTS, LTE, Internet, etc.
There are no restrictions on the combination of WAN types in a project. Point-to-point, line and node network topologies can be set up. Hybrid configurations of these basic structures are also possible.
A station can be linked using two transmission paths to permit redundant data transmission. The two paths can be of the same type or different, e.g. dedicated line plus GPRS, or ISDN plus wireless.
The following network topologies are possible in the WAN:
The graphics below show examples of different network topologies that can be implemented with the components listed above.
SINAUT ST7cc/sc control station with redundant WAN connection
Different communication media in a SINAUT ST7 system
A number of different variants can be selected as components of the central control center:
SINAUT ST7cc
PC control center based on WinCC
This is the ideal control center system for both SINAUT ST7 and SINAUT ST1. It has been designed specifically for event-driven and time-stamped data transmission on the SINAUT system and can be set up as a non-redundant or redundant system (to supplement the WinCC/PCS 7 redundancy package).
PCS 7 with PCS 7 TeleControl
This is the ideal control center system for plants in which larger local automation tasks have to be connected to telecontrol interfaces. In addition to SINAUT ST7, remote stations with other communication protocols can be connected, e.g. over DNP3 or IEC -60870-5-101/-104. 1)
WinCC TeleControl
Control center system for plants with the WinCC HMI software, expanded with telecontrol connections. WinCC TeleControl provides the connection of SIMATIC substations that communicate via IEC 60870, DNP3 or SINAUT ST7.
SINAUT ST7sc
OPC server for interfacing control centers from other vendors via the OPC Client function
The SINAUT telecontrol technology can also be connected to control center systems from other vendors via the “Data Access Interface”. ST7sc features extensive buffer mechanisms which prevent data from being lost even if the OPC client fails. It can be connected to non-redundant or redundant clients.
Like the substations, the control center comprises a SIMATIC S7-300, an S7-400 or an S7-1500 controller.
This solution is suitable for simpler control centers in which only an up-to-date process image of the process data available in the stations is required. The station process control can be influenced by entering commands, setpoints or parameters. This S7-300, S7-400 or S7-1500 control center can also be used to extend a PC control center (SINAUT ST7cc or ST7sc), e.g. for data output on a panel and/or as an emergency operating system.
SINAUT ST7cc control center system with connected substations (RTU)
The following conventional WANs can be used for data transmission:
Telecontrol communication is also possible via IP-based networks:
In the stations, the SINAUT software ensures that process data is transmitted between CPU and control center, e.g. ST7cc, and from CPU to CPU in the event of changes. Connection, CPU or control center failures are displayed. A data update for all participating communication partners is performed automatically following debugging or startup of a CPU or of the control center.
To enable subsequent and correct archiving of process data in the control system, all data frames are already assigned a time tag at their place of origin. The entire network is synchronized automatically – including daylight saving time changeover.
A special property of the TIM communications module used in the SINAUT ST7 system is the capability for saving data which must not be lost in the event of a connection fault or if the partner fails. A memory capacity is provided for up to 56,000 message frames.
The memory capacity helps to save money on dial-up networks. Various priorities can be assigned to the data to be transmitted. At high priority, a dial-up connection is established immediately. At low priority, data is initially saved in the TIM. This data is transmitted on the next connection that is made with the partner for any reason, for example if an item of information with a high priority is to be transmitted, or if the partner sets up a connection in order to exchange data.
It is precisely because the TIM module can save data and transmit it at a later point in time with a time stamp that the use of a suitable control center system must be ensured. It must also be possible to continue to process this data, specifically as regards subsequent archiving, if the data is received in the control center delayed by a number of hours or even days. Also archive compressions such as the creation of mean, hourly and daily values cannot be performed until all data for the relevant period has been received. The standard SINAUT control center on the basis of WinCC, when supplemented with the SINAUT software ST7cc, is ideal for this task.
In industries in which SINAUT is used, the terminals are distributed across wide areas and are often situated in locations that are difficult to access. Faults which require a visit to be made to a terminal of this type are associated with long journeys. SINAUT ST7 can provide the ideal solution for such circumstances: Remote programming and diagnostics via the telecontrol network. All diagnostics and programming functions provided by SIMATIC and SINAUT for station automation and WAN communication can be used via the telecontrol path – without interrupting process data transmission.
In order to alert standby service personnel, event-driven text messages can be sent to mobile phones from the CPUs. An acknowledgment that a message of this type has been received can be sent back to the sender CPU from the mobile phone. A text message can also be output as email, fax or voice mail if the mobile service provider offers these options.

Protocols
IEC protocol 60870
IEC 60870-5-101, -104 are standardized, vendor-independent telecontrol protocols. They enable remote communication via both conventional and IP-based WANs. The following modules are offered for implementation of an RTU with IEC 60870-5 based on the SIMATIC: CP 1243-1, CP 1243-8 IRC, CP 1542SP-1 IRC, TIM 1531 IRC plus the compact RTU3000C module.
Possible operating mode in the IP-based WAN:
DNP3 protocol
The DNP3 protocol (distributed network protocol) is a standardized, manufacturer-independent telecontrol protocol. It enables remote communication via both conventional and IP-based WANs.
Possible operating mode in the IP-based WAN:
Possible operating modes in the conventional WAN:
SINAUT ST7 protocol
SINAUT ST7 enables SINAUT communication via both conventional and IP-based WANs. In addition, the addressing options have been extended:
The ST7 protocol also supports “PG routing”, i.e. remote programming and remote diagnostics via the WAN without interrupting SINAUT data traffic. PG routing and data traffic share the available bandwidth on the transmission path; PG routing is simply allocated a higher priority.
Possible operating mode in the IP-based WAN:
Possible operating modes in the conventional WAN:
SINAUT ST1 protocol
This protocol is used in the SINAUT ST1 system, which is based on the SIMATIC S5 system. However, the SINAUT ST7 system also supports this protocol. Existing SINAUT ST1 systems can thus be further expanded with the SINAUT ST7 system, or existing system components can be replaced with ST7 devices.
Possible operating modes:
Please note that only modems/transmission devices suitable for 11-bit asynchronous characters may be used in both polling modes. However, the “spontaneous” mode supports transmission with both 11-bit and 10-bit asynchronous characters.
All networks and all transmission media can be combined in any way in a telecontrol project – both with each other in “node structures”, as well as in parallel in star topologies or in redundant configurations.
The graphics below show a selection of different topologies that can be implemented with the telecontrol components.
Basic topologies
Differently structured telecontrol networks can be implemented in the wide area network (WAN) based on the following four basic topologies.
Media versions
Depending on the support provided by the selected telecontrol protocol, various transmission media are available for these basic topologies, for example, dedicated line, private wireless networks, mobile wireless networks, dial-up networks (wireless/landline), DSL over Internet.
Some of these media versions are shown in the example of the star topology.
Combinations of basic topologies and media versions
Through a combination of several basic topologies of the same or different media versions, it is additionally possible to design more complex network topologies, even with redundant communication paths. This allows optimum adaptation to process requirements and to the existing infrastructure.
