OverviewIf it is the case that a SIMATIC PCS 7 system has to communi-cate with a remote control center of a third-party supplier using the IEC 870-5 telecontrol standard, the IEC 870-5-101 (serial) and IEC 870-5-104 (TCP/IP) telecontrol protocols can be imple-mented in the SIMATIC PCS 7 automation systems.
Possible fields of application include:
• Interfacing of power plant automation based on SIMATIC PCS 7 to network control centers for power distribution
• Interfacing of pumping and compressor stations automated using SIMATIC PCS 7 to higher-level control centers for gas, oil or water pipelines
In this case, the IEC 870-5-101 supports classic WAN connec-tions over modems and dedicated lines. Using the
IEC 870-5-104 protocol, TCP/IP-based WAN connections such as Internet/DSL or GPRS can be used. Depending on the proto-col, either the CP 441 (IEC 870-5-101) or CP 443-1EX20 (IEC 870-5-104) is used as the communication module in the au-tomation system.
The materials required to design a telecontrol link, e.g. TCP/IP router, CP 443-1EX20, CP 441-1, dedicated line modem cable, etc., are accessories which are not included in this catalog.
In the SIMATIC PCS 7 automation system, additive driver blocks from the SIPLUS RIC IEC on S7 library carry out the interface adaptation for communication using the IEC 870-5-101 or IEC 870-5-104 standardized protocols. As usual with SIMATIC PCS 7, configuration is carried out using the SIMATIC Manager.
Note:
The blocks of the SIPLUS RIC IEC on S7 library can be used together with automation systems from the SIMATIC PCS 7 V7 process control system.
For the telecontrol configurations described in this catalog section, use of the SIPLUS RIC IEC on S7 library is independent of SIMATIC PCS 7 TeleControl.

OptionsRedundant telecontrol configurations can be implemented analogous to the configurations described in the overview. One example configuration of each of the IEC 870-5-101 (serial) and IEC 870-5-104 (TCP/IP) telecontrol protocols is shown below.
Redundant configuration with AS 412H/AS 414H/AS 417H and IEC 870-5-101 telecontrol protocol (serial)
• The control center is linked via a serial telecontrol connection with IEC 870-5-101 protocol to a CP 340 or CP 341 in an ET 200M station of the SIMATIC PCS 7 system.
• If the master system fails, the standby system of the redundant automation system takes over data exchange with the control center bumpless via the CP 341 in the ET 200M station.
• Failure of the master system can be signaled to the control center.

Redundant configuration with AS 412H/AS 414H/AS 417H and IEC 870-5-104 telecontrol protocol (TCP/IP)
• The control center is linked via a TCP/IP-based WAN to the SIMATIC PCS 7 system bus.
• The control center establishes a TCP/IP connection to an AS subsystem with each of the two CP 443-1EX20 via which the redundant automation system is integrated into the system bus.
• The control center starts the IEC 870-5-104 telecontrol proto-col via the TCP/IP connection to the master system, and mon-itors the TCP/IP connection to the standby system using test frames.
• If the master system fails, the control center signals the asso-ciated connection as being faulty, and starts the
IEC 870-5-104 telecontrol protocol via the TCP/IP connection to the standby system. It then attempts to reestablish the faulty connection.
As a specialist for complete solutions in the product and system business, we would be pleased to advise you concerning gen-eration of an individual configuration and the selection of acces-sories. If required, we can also supply preconfigured bundles or turnkey outstations installed in wall enclosures, cabinets or con-tainers.
