Add a PORT_TEST Connection that enables you to add a PLC_Test connection. The PLC_Test Connection provides simulated data for the Communication Driver by setting the simulated data parameters.
Add a PORT_TEST connection
-
In the OI Server Manager, expand Default Group, and then expand Local.
-
Expand the Simulator Communication Driver, then expand Configuration.
-
Right-click Configuration, then select Add PORT_TEST Connection from the shortcut menu.
The New_PORT_TEST_000 object appears in the hierarchy. Rename it, if desired
Add a PLC_TEST connection
-
Right-click PORT_TEST connection in the hierarchy, then select Add PLC_TEST Connection from the shortcut menu.
The New_PLC_TEST_000 object appears in the hierarchy. Rename it, if desired.
Note: The PLC_Test hierarchy name cannot contain spaces.
You can change the PLC_Test connection name while the Simulator Communication Driver server is active. After the name is changed, client applications using the old name cannot register data with the Communication Driver. Data for existing queries is set to bad quality. Try not to make changes to the hierarchy name after you develop a large client application.
Note: The PLC_Test hierarchy name cannot contain spaces.
Change an existing PLC_Test hierarchy name
-
In the OI Server Manager, expand the node hierarchy tree to display the target node object you wish to rename.
-
Right-click on the node to be renamed, and select Rename.
-
Type the name and press Enter.
Deleting a PLC_Test connection removes the node and all defined data simulation configuration. Deleting a simulation hierarchy is not reversible. If you delete a test hierarchy in error, you must re-enter the device information.
New requests for data that use the deleted hierarchy name are rejected. Data for existing queries is set to bad quality.
