DESCRIPTION

OPC ( OLE for Process Control ) is an industry
standard for transferring process data between
a server and one or more client applications.

The Trusted
link between a Trusted
OPC clients. Using Ethernet Interface cards
within the Servers host PC, it connects to one
or more Trusted
applications can connect to the server using
Microsoft COM ( or DCOM over a network ).
Each client can browse the server to view the
available tag references. Using these
references, the clients can then arrange for
groups of tags to be synchronously updated at
defined intervals. Values may also be written
asynchronously to the server.

The block diagram overleaf shows how the
OPC Server fits between the Trusted
hardware and one or more OPC client
applications.

The server OPC Server may be considered to
comprise three main functions. These are; the
Browse Interface, the OPC Server Group
Interface and the Communications Interface.

The server provides a list of tag
references that OPC clients can browse
in a standard manner. The root node is
the Trusted
sub-items are groups, which are used to
configure and locate the tag names,
which may be located within them.
These tags are then identified by the full
path name of the tree.

When a client attaches to the server, a
unique server object is created within
the main Trusted
client can create and edit groups within
this server object. Each group has a
number of tag references and an update
rate. Every time the tags are to be
updated, the server will inform the client
of the new values, quality, time, etc.

When the groups within an OPC server
request tag data is to be updated, the
tag references are passed to the
communications interface. This will
read the values from the appropriate
Trusted
tag data back to the server groups.

Data can also be written to the tags.
The tag references and values are
passed to the communications interface,
which will then send the data to the
