Notes:

With the telecontrol configurations described below for connection of SIMATIC PCS 7 automation systems to a third-party control center, use of the SIPLUS RIC for SIMATIC S7‑400 library is independent of SIMATIC PCS 7 TeleControl.

The materials required to design a telecontrol link, e.g. TCP/IP router, CP 443‑1, CP 441‑1, CP 341, dedicated line modem, cables etc. are accessories which are not included in this catalog. For additional information and ordering data, see IK PI and ST 70 catalogs

Telecontrol connection for single SIMATIC PCS 7 automation systems (single station)

Configuration examples of the telecontrol connection of SIMATIC PCS 7 automation systems of single station design with the IEC 60870‑5‑101 and IEC 60870‑5‑104 telecontrol protocols

Depending on the protocol, the following automation system connection options can be used for communication:

• CP 441 (IEC 60870‑5‑101)
• PN interface in CPU/CP 443‑1 (IEC 60870‑5‑104)

In the SIMATIC PCS 7 automation system, additive driver blocks from the SIPLUS RIC library for SIMATIC S7‑400 adapt the interface for communication using the IEC 60870‑5‑101 or IEC 60870‑5‑104 standardized protocols. Configuration is performed using the SIMATIC Manager as usual for SIMATIC PCS 7. This equally applies to automation systems designed as single station or redundant station.

Telecontrol connection for redundant SIMATIC PCS 7 automation systems (redundant station)

Redundant configuration with IEC 60870‑5‑101 telecontrol protocol (serial)

Configuration example of the telecontrol connection of redundant SIMATIC PCS 7 AS with the IEC 60870‑5‑101 telecontrol protocol

• The control center is linked via a serial telecontrol connection with IEC 60870‑5‑101 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 IEC 60870‑5‑104 telecontrol protocol (TCP/IP)

Configuration example of the telecontrol connection of redundant SIMATIC PCS 7 AS with the IEC 60870‑5‑104 telecontrol protocol

• 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 communication interfaces via which the redundant automation system is integrated into the system bus.
• The control center starts the IEC 60870‑5‑104 telecontrol protocol via the TCP/IP connection to the master system and monitors the TCP/IP connection to the standby system using test frames.
• If the master system fails, the control center signals the associated connection as being faulty, and starts the IEC 60870‑5‑104 telecontrol protocol via the TCP/IP connection to the standby system. It then attempts to reestablish the faulty connection.
