Introduction to PCIS-OPC
The PCIS-OPC software is an OPC compliant server that enables data
exchange between OPC clients and NuDAQ PCI data acquisition cards.
The OPC server is fully compliant with OPC Data Access Specification 2.0.
It follows the requirements of the OPC specification to provide access to
data to an OPC client. This server implements version 2.04 of the OPC
custom interface that is typically used by C++ and Delphi programs. Also it
provides immediate compatibility with a very wide range of application
software systems. Any software system with OPC client capability can
access the OPC server to monitor and control data to and from the
NuDAQ PCI data acquisition cards.
The software includes the NuDAQ PCI card OPC server. A graphical
configuration utility is bundled in the OPC server to let you configure and
diagnose the operation of the OPC server. You can set the attributes of
each data item (I/O point). OPC client software can then access these
data items via this name assigned in the server.
