Version 6.0
OPC Server Configuration
To configure OPC data points, select the OPC Server button from the S 3 Main Screen. This will display the OPC
Server Configuration dialog box which lists all of the tags available for activation by the server.
note
For the S 3 server to function, the S 3 hardware key must have the oPC server function enabled.
The available tags shown, were created during the port configuration process. When a Modbus, Triconex, Eagle
or other device is configured it is added to the S 3 tag name database. All of the points in this tag name database
are automatically set up by S 3 for use by the OPC server. This greatly simplifies OPC tag management.
The OPC Server Configuration dialog box displays the tagname, type and origin information along with its OPC
status, either Active or Inactive. To make a tagname available to OPC Clients, select the tagname and click on
the “Activate” button.
In the example to the left, the EQP
Controller is selected. Its tagname is
“Controller”, it originates at S 3 port 1
point 1, is an “I” (input), and has an
OPC State of “Inactive”.
This is a “top level” view of the devices
and their status. In the above example
this single point “Controller” actually
is a compound point with a variety of
subordinate data available to the OPC
client.
To view this data, select the “Properties”
button.
