Telecontrol system with SINAUT ST7, IEC 60870-5 or DNP3
Telecontrol systems for extensive, advanced applications in the process industry are based on standardized protocols such as IEC 60850 and DNP3 (IEEE 1815) or special telecontrol protocols such as the proven Siemens protocol, SINAUT ST7. Our telecontrol system offers fully automatic monitoring and control of remote terminal units based on SIMATIC S7 or compact SIMATIC RTU3000C remote terminal units, which exchange data with each other and with one or more control centers via a wide variety of communication networks.
It facilitates an integrated communications concept (TIA) and complete integration into the SIMATIC environment. The modular design and the support of a huge variety of line system configurations and operating modes including Ethernet permit the design of flexible network structures that can also contain redundant links.
The networks can be optimally adapted to the respective local conditions using all transmission media (mainly IP-based networks, e.g. DSL, mobile wireless, as well as conventional networks such as dedicated line, radio, dial-up networks).

应用
The telecontrol components have proven themselves 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:
Safe supply of drinking water, gas or district heating for private and industrial consumers via branched networks
Economical transportation of gas, oil or oil products through pipelines
Reliable recording and transmission of process data from environmental monitoring systems
Remote monitoring of wastewater systems
Control of beacons, unit-type district heating power stations, conveyor systems or transportation systems
设计
The telecontrol system is based on the SIMATIC systems S7-1500, ET 200SP, S7-1200, S7-300, S7-400, the RTU3000C family and WinCC/PCS 7. It adds telecontrol functions to these systems using the hardware and software components listed below.

功能
Network configurations and operating modes
The telecontrol components support the set-up of complete hierarchical communication networks comprising stations, node stations and control center.
IP-based WAN such as DSL/internet, GPRS, UMTS, LTE, 5G, etc. as well as conventional WANs such as dedicated line, radio and dial-up networks can be used for the exchange of information between the individual devices.
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. two Ethernet connections or dedicated line plus Ethernet.
The following network configurations are possible in the WAN:
"Point-to-point"
"Line"
"Star"
"Tree"
"Ring"
The graphics below show examples of different network configurations that can be implemented with the components listed above.

The control center
The control center consists of a PC with SCADA software with telecontrol connection for the corresponding protocols and, if necessary, additionally a master PLC of the SIMATIC S7- type.
A number of different versions can be selected as components of the central control center:
SINAUT ST7cc
The PC control center is based on WinCC V7
This is the ideal control center system for SINAUT ST7. 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 combined with telecontrol connections. In addition to SINAUT ST7, remote stations with other communication protocols can be connected, e.g. over DNP3 or IEC -/-104.
WinCC TeleControl
Control center system for plants with the WinCC V7 HMI software, expanded with telecontrol connections. WinCC TeleControl offers the connection of SIMATIC substations communicating 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.

IP-based networks
Telecontrol communication is performed via IP-based networks:
Via public networks and the internet using DSL or GPRS/UMTS/LTE/5G
Wirelessly, by using special wireless systems optimized for Ethernet, e.g. the components of the SCALANCE W IWLAN system
Distances of up to 120 km can then be covered via fiber-optic cables, e.g. by using SCALANCE X switches with optical ports
Copper dedicated lines, private or leased
Conventional networks
The following conventional WANs can be used for data transmission:
Copper dedicated lines, private or leased
Private wireless networks (optionally with time slot procedure)/TETRA
Dial-up networks (e.g. analog)
Change-driven data transmission
In the stations, the telecontrol software ensures that process data is transmitted between CPU and control center 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.
Time-of-day always up to date
To enable subsequent and correct archiving of process data in the control center system, all data frames are already assigned a time stamp at their place of origin. The entire network is synchronized automatically – including daylight saving time changeover.
Local data storage
A special property of communications modules used in telecontrol systems is the capability for saving data which must be secured against loss in the event of failure of a connection or partner.
Since the telecontrol modules save data and transmit it at a later point in time with a time stamp, a suitable control center system must be used. 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. Archive compressions such as the creation of mean, hourly and daily values also cannot be performed until all data for the relevant period has been received.
Remote programming and diagnostics
In industries in which telecontrol systems are used, the stations 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 station of this type are associated with long journeys. A telecontrol system offers the optimal solution for this: Remote programming and diagnostics via the telecontrol network. All diagnostics and programming functions provided by SIMATIC RTUs for substation automation and WAN communication can be used via the telecontrol path - without interrupting process data transmission.
Alarms as text messages
In order to alert standby service personnel, event-driven text messages can be sent to cell phones from the process stations. An acknowledgment that a message of this type has been received can be sent back to the sender CPU from the cell phone.
