User interface of the OS process control system with freely positionable windows

The operator system of the SIMATIC PCS 7 process control sys- tem permits user-friendly and secure execution of the process by the operating personnel. The operator can observe the pro- cess sequence by means of various views and intervene to con- trol the system when necessary.

The operator system architecture is extremely variable and can be flexibly adapted to different plant architectures and customer requirements.

The basis is formed by perfectly coordinated operator stations for single-user systems (OS single stations) and for multi-user systems with client/server architecture.

The system software of the operator stations is available in differ- ent levels based on the number of process objects (PO) used:

•250, 1000, 2000, 3000 or 5000 POs per OS single station

•250, 1000, 2000, 3000, 5000 or 8500 POs per OS server (with client/server architecture)

The number of POs for an operator station can be increased up to 5000 (OS single station) or 8500 (OS server) at any time by means of PowerPacks to allow for higher requirements or system expansions.

7Flexible, modular architecture with scalable hardware and software components for single-user and multi-user systems

7High-performance operated stations based on standard PC technology with Microsoft Windows XP Professional / Server 2003, can be used in office or industrial environments

7Client/server multi-user systems with up to 12 OS servers/ pairs of servers, each for 8500 process objects (PO) and up to 32 OS clients per server/pair of servers

7High-performance archive system based on Microsoft SQL server with cyclic archives and integral data backup, option- ally with long-term archiving via StoragePlus/central archive server (CAS)

7OS health check for monitoring important server applications

7Integration of modifications without interrupting runtime oper- ations, and online testing through selective loading of redun- dant servers

7Optimized AS/OS communication:

data transmission only following change in data, independent of AS reply cycle; suppression of nuisance alarms

7User-friendly process control and high operational reliability, also in conjunction with multi-screen technology

7Extended status displays through combination of status and analog values with alarm information

7Alarm suppression during startup or on malfunction of a sen- sor/actuator

7Dynamic or manual hiding of visual and acoustic alarms that are unimportant depending on the plant status, e.g. during plant startup (however, all messages are recorded and ar- chived); with manual hiding, the duration until display takes place again can be set.

7Alarm priorities as additional attribute for filtering important messages

7Central user management, access control, electronic signa- ture

7Sign-of-life monitoring for subordinate systems connected to the plant bus

7System-wide time synchronization based on UTC (Universal Time Coordinated)
