What is NAPOPC Server | |

Introduction
| |
OPC is a series of standards specifications. The first standard (originally called simply the OPC Specification and now called the Data Access Specification) resulted from the collaboration of a number of leading worldwide automation suppliers working in cooperation with Microsoft. Originally based on Microsoft's OLE COM (component object model) and DCOM (distributed component object model) technologies, the specification defined a standard set of objects, interfaces and methods for use in process control and manufacturing automation applications to facilitate interoperability. The COM/DCOM | |
technologies provided the framework for software products to be developed. There are now hundreds of OPC Data Access servers and clients.
NAPOPC DA Server is an out-of-process OPC server which uses an Explorer-style user interface to display a hierarchical tree of devices and groups with their associated tags. A group can be defined as a subdirectory containing one or more tags. A device may have many subgroups of tags. All tags belong to their device when they |
 |
are scanned to perform I/O. (The "OPC" stands for "OLE for Process Control" and the "DA" stands for "Data Access".). | |
