3-14 ProcessLinx TagMap Configuration
Table 3.C TagMap Data Attributes
Attribute Description
Server The Server field displays the defined OPC Server for this half of the
TagMap.
OPC Item Use the OPC Item area to enter the specific tag in the OPC Server.
For OPC v2.0 compliant servers, “Browse” opens the database for
point-and-click OPC Item entry. When the Item is selected, its tag
name is entered in thus field.
Tip: To browse OPC Items from ProcessLogix, export the Control
Builder configuration. Refer to Creating a ProcessLinx TagMap
Configuration on page 3-15.
If you want to only monitor an item from a Server then it is not
necessary to define the OPC Item for the other Server, leave the
OPC Item field blank. In this case, the value of the undefined item
displays as <Invalid Tag> in Monitor mode. OPC items can be
added/edited in runtime.
Access Path Access Path sets the OPC path for the specific OPC Item.
For ProcessLogix OPC Server and most External OPC Servers this
can be left blank. If this parameter is implemented within the
External OPC Server, consult it’s documentation for specifics.
For example, the access path may be COM1 or COM2.
