Why the OPC server is so important in the
company operation or systems? It is important to note that some OPC
specifications are published; others are available only to member of the OPC foundation.
So whilst no company "owns" OPC and anyone can develop an OPC server,
whether or not they are a member of the OPC foundation, non-members will not
necessarily be using the latest specifications.
Anyone can integrate OPC
products, and there is no pre-requisite for the system integrator to belong to
any organization. It is therefore up to each company that requires OPC servers
to ensure that their products are certified and that their system integrators
have the necessary training. Hence, the OPC server is a crucial element for
computer system in company.
