The operator system of the SIMATIC PCS 7 process control system allows easy and safe control of the process by the operating personnel. The operator can observe the process sequence by means of various views and intervene to control 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 can be expanded by cumulative SIMATIC PCS 7 OS Runtime licenses for 100, 1 000 and 5 000 process objects (PO) up to following configuration limits:

• 8 500 POs per OS Single Station
• 12 000 POs per OS Server (with client/server architecture)
