CHAPTER 14 – Using CX-Supervisor as an OPC Client
How is OPC going to improve my bottom line?
From a business perspective, the use of OPC for connectivity promises to reduce the cost of
automation, control, and integration solutions. By using OPC compliant products, significant savings
can be achieved through shorter development efforts and a wide choice of vendor hardware and
software solutions. For every automation system installed today, a significant amount of time and
money is spent ensuring that the system can share information with other systems and devices. OPC
will save the customer time and money by eliminating a lot of the system integration problems
caused by lack of open standards that exist between automation devices, systems, and manufacturing
software. After an automation system is installed, OPC will not improve business bottom line
directly; however, OPC will provide a common method to access real-time information. The real key
to improving the bottom line is to distribute and use the information throughout the business' value
chain.
