Conversion to an up-to-date operator control level is an obvious first step of a comprehensive modernization of OpenPMC systems: SIMATIC PCS 7/OPMC can be used as a modern operator control and monitoring system in combination with existing field devices, input/output devices, controllers, and associated engineering data. When Siemens OpenPMC systems are migrated using SIMATIC PCS 7, existing OpenPMC operator control stations (SIMATIC IT Historian Server und Clients) are replaced with SIMATIC PCS 7 operator systems (single stations or client-server systems). The OS single stations and OS servers of these PCS 7/OPMC operator systems can be operated redundantly as well as individually. The OPC server of SIMATIC IT Historian is used for data exchange between OpenPMC controllers and PCS 7/OPMC server.

The Data Base Automation (DBA) software is used for engineering of the PCS 7/OPMC operator systems. The data source for DBA is the SIMATIC IT Historian Management Console, which will continue to be used for configuring the OpenPMC controllers.

For system expansions, it is possible to use the SIMATIC PCS 7 AS 41x controller and SIMATIC process I/O in parallel with existing installations. This requires the use of the SIMATIC PCS 7/OPMC operator control and monitoring system.

Advantages of migration to SIMATIC PCS 7

The migration of an old system to SIMATIC PCS 7 pays off many times over: It assures the continuity of process control system investments, makes the systems more efficient and productive, and extends the system service life in a cost-effective manner.

Additional winning advantages:

  • Step-wise or complete system modernization

  • Future viability assured due to use of a modern and flexible process control system

  • Modern technology reduces the risk of plant outages

  • Increased productivity due to higher availability of the new process control system

  • Reduced costs for stocking spare parts and for maintenance

  • Investment protection based on the Totally Integrated Automation (TIA) concept

  • Use of SIMATIC PCS 7 reveals potential for process optimization, thus increasing production output

  • Resource optimization and quality improvement due to increased information density and quality

  • SIMATIC PCS 7 establishes the basis for connection to a Manufacturing Execution System (MES)
