Following the launch of Release 1.0 of OPC (OLE for Process Control), and the formation of the OPC Foundation (C&I, October 1996, page 7), several OPC products and services have been previewed.

Fisher-Rosemount says that OPC is an important part of its PlantWeb system. It’s launched the Real Time Data Server for the DeltaV system, based on OPC.

Siemens has announced OPC support in its Simatic range. An OPC server for S7 is due out early this year. Also, an OPC client interface will be included in all Simatic MMIs, bringing integration to, for example, Siemens’ WinCC visualisation system.

Honeywell says that OPC will be a critical element of its TotalPlant Solution system. And, Intellution says that VisualBatch is OPC-enabled – exchanging configuration and real time data.

Rockwell Software, too, says that it intends to embed the OPC specification within its RSTools, RSView32, RSLinx, RSServer and Toolkit – ActiveX Controls.

* Several technical sub-committees were implemented by the OPC Foundation at its most recent meeting in Dallas late last year. Areas covered include: the next OPC revison; alarming; historical access; security; event logging; and batch automation.

* The OPC Foundation plans to work closely with the ISA’s recently-formed SP95 standard committee in the USA. This is intended to establish interfaces for standard integration of control operations with enterprise systems – the middleware.
