browse capability the External Server must be registered on the local
PC. Each pane contains a tree view listing of all available OPC items
within the Server.
You select an OPC item on one side and the corresponding item to map
to on the other and click ÅMAPÆ. Alternatively, the user can select an
item from one side and drag it into an OPC Item on the other to create
a tag mapping.
The data flow direction is decided by the direction of the Parent Group.
The tags mapped during the current session are displayed in the
“Selected Mappings” window. Selecting cancel, clears all selected maps
for the current session.
To remove a TagMap from an edit session, select the TagMap you want
to delete in the “Selected Mappings” pane and press Delete. Clicking
OK accepts the new maps (if any) and loads them under the current
Group. TagMaps can be added in runtime mode.
In ProcessLogix R500 systems, it may be necessary to define groups of
tags within ProcessLogix into Areas. The Areas will display in the OPC
Server address space.
In ProcessLogix R400 systems, the Top Level (root) Node in the
Browse Tree was displayed with an asterisks and all items could then be
defined from this top level name (such as *.FC151.PIDA.SP).
ProcessLogix R500 systems still support the use of the * as a prefix on
an OPC Item but are now displayed under the defined area.
Testing a ProcessLinx
Configuration
A ProcessLinx configuration can be tested after the above steps are
implemented. It is recommended at the initial onset of testing the
ProcessLinx interface that you set the debug mode to 5, turn on the
Show flags (i.e. Show Errors, Show Events and Show Send), and specify
an error log directory to view any errors. You can use the View ⇒
Monitor function to view the data tag values in real time while testing.
After all TagMaps have been successfully setup and are working
according to the Interface Control Strategy in step 3.3, turn off the
debug flags with the exception of the Show Errors flag.
