RS-422 (Siemens 3964R) Interface

If you encounter problems with the RS-422 (Siemens 3964R) interface, you can use Procedure 5-4on page 5-17.Although this procedure describes how you test an Ethernet network from a laptop computer, you can use the same steps to test the RS-422 (Siemens 3964R) interface until you reach Step 7. Instead of using the ping command, use the tcm command. Using the tcm command allows you to view information about the status of communications on the RS-422 port during the debugging process. You can also use two other commands called tcm mask all and tcm unmask VIN to log the RS-422 port activity.

Application Program Interface (API)

The Application Program Interface (API) is a software application that runs separately but concurrently to Visual Supervisor. It collects data and sends it to another software application.

If you have problems running the API, check the version number of Device Control Module (DCM) software the controller is running. You must have the DCM firmware at version 4.06 or higher to successfully run the API.

In order for the API to collect data, you must set “History=VIN” in VSMain.ini on the VS host computer. For further details about VSMain.ini, refer to the Visual Supervisor User’s Guide (part number 39-30-34823).
