Integration in process control Engineering

The telecontrol center for the outstations (RTU) is integrated into the process control of the SIMATIC PCS 7 process control system in the form of an operator station in single station or server design (also redundant as option). No additional auto- mation system for conditioning telecontrol-specific data need be planned in the SIMATIC PCS 7 system. With large quantity frameworks, a PCS 7 TeleControl operator station (single sta- tion/server) is preferably responsible only for the telecontrol mode (dedicated). With small quantity frameworks, a server or a single station can also control SIMATIC PCS 7 automation systems (AS) in central plant areas in addition to the telecon- trol systems (dual-channel mode).

The OS clients of the client/server multi-user system are able to display data from RTUs and SIMATIC PCS 7 AS - which they receive from a server with dual-channel functionality or from two separate servers - together in one process image. Display is primarily on faceplates for process objects such as motors, valves etc., but also by means of trend curves and messages.

To enable engineering of the PCS 7 TeleControl operator sta- tion (single station/server), the functions of the engineering station of the SIMATIC PCS 7 process control system are expanded by DBA technology (Data Base Automation) and the SIMATIC PCS 7 TeleControl block library.

Communication with the outstations (remote terminal units)

For communication with the outstations, SIMATIC PCS 7 TeleControl uses the SINAUT ST7, DNP3 and Modbus protocols (both via serial and TCP/IP communication connections) as well as IEC 870-5-101 (serial) and IEC 870-5-104 (Ethernet TCP/IP).
