Integration and uniform operation with SIMATIC PCS 7 OPEN OS

Process plants often run for several decades, are often extended by plant sections or partly modernized. The automation landscape develops accordingly inhomogeneous and so combinations of control technology systems (operator stations & controllers) from different manufacturers can be found. The resulting breaks in operation hinder uniform process control. Standardize the operation of heterogeneous automation components: SIMATIC PCS 7 offers a standardized extension in the form of SIMATIC PCS 7 OPEN OS. With its help, different systems from various manufacturers can be integrated in a structurally compliant way.

Uniform operation and monitoring

Seamless integration into the SIMATIC PCS 7 process control system

The simple integration of package units, third-party controllers and machine-oriented controls is achieved by OPC Unified Architecture (OPC UA). OPC UA is a manufacturer- and platform-independent international standard for industrial communication. The SIMATIC PCS 7 OPC Client also enables the connection of OPC servers from other manufacturers. Process data, alarm information, measured values and process variables, for example, are then exchanged via an authorized OPC communication channel. The result is a higher degree of integration of the plant despite heterogeneous controller hardware as well as a uniform and therefore less error-prone operation of the entire plant.

The Database Automation Tool (DBA) is the heart of SIMATIC PCS 7 OPEN OS. The DBA defines the interfaces and integrates the various controllers into the operator station of SIMATIC PCS 7. Machine-oriented controls such as SIMATIC S7-1200 and S7-1500 can also be integrated into the SIMATIC PCS 7 operation management level. In this way, the following components can be uniformly operated and monitored in a higher-level process control:

  • Controllers of other manufacturers (Third-Party)
  • Siemens own automation systems 
  • Package units
