PCS 7 TeleControl Operator System

Single-user and multi-user systems

Depending on the magnitude of the automation project and the required number of operator stations, the SIMATIC PCS 7 TeleControl Operator System can be configured either as a sin- gle-user system (PCS 7 TeleControl OS single station) or as a multi-user system with client/server architecture:

Single-user system

-Up to 5 000 process objects

-Up to approx. 3 000 measuring points

-Low number of operator stations

Multi-user system (client/server)

-Up to 8 500 process objects per OS server

-Up to approx. 5 000 measuring points per OS server

-Up to 32 operator stations (OS clients)

In a single-user system architecture, all operation and moni- toring functions for a complete project (plant/unit) are con- centrated in one station.

A multi-user system has up to 32 operator stations (OS clients) which are supplied with data from one or more servers

(OS server or PCS 7 TeleControl OS server) via the terminal bus.

The multi-client architecture of the multi-user system allows an OS client to call data from various servers, e.g. from two separate servers for local units and for units connected by means of PCS 7 TeleControl.

The PCS 7 TeleControl OS server of the multi-user system can also have a redundant design. All internally generated infor- mation (e.g. alarm states or results of calculations) is matched in the redundant pair of PCS 7 TeleControl OS servers.

The graduated scalability of the process objects of PCS 7 TeleControl OS single station and PCS 7 TeleControl OS server permits fine and flexible matching of the SIMATIC PCS 7 TeleControl Operator System to the size of the respective automation project.

Dual-channel operation with single-user and multi-user systems

PCS 7 TeleControl OS single station and PCS 7 TeleControl OS server are preferably used just for telecontrol functions (dedi- cated), but can also access central SIMATIC PCS 7 plant areas via an additional second channel in the case of small quantity frameworks (double-channel operation). In this way, data from the RTUs of the telecontrol system can be displayed in one process image together with data from SIMATIC PCS 7 AS.
