Open, Modular Architecture Controls at GM Powertrain — Non-Technical Issues

Reliability of PC Hardware Integration of open control systems Liability of open control systems Support of open control system implementations Relationship between user and vendor Progression toward OMAC systems Globalization of the OMAC concept The OMAC concept has been presented to many control vendors, equipment builders, and end users, and the OMAC direction is being embraced by many companies. However, during the interactions with many companies about OMAC, many non-technical issues were raised concerning the feasibility of large-scale implementation of OMAC-based systems on the factory floor. Many similar concerns were voiced repeatedly, and perspectives from GM Powertrain are presented in this section to address these issues.

ISA TECH/97 Highlights From Anaheim, Calif., Day Three

OPC on the ISA TECH/97 Floor OLE for Process Control (OPC) was demonstrated on the floor at ISA TECH/97. Based on Microsoft's component object model technology, OPC allows components in a networked system to share process data. The Microsoft and OPC booths demonstrated the interoperability of products from 16 foundation members. The booth demonstrations show real-time data flowing between hardware such as programmable logic controllers and distributed I/O from various manufacturers to human-machine interface and supervisory control and data acquisition software systems over Ethernet using TCP/IP.
