Net API? Are you a OPC Foundation member? Thanks in advance. To solve this problem I need to copy the dll files OpcRcw. Well Site Automation Conference I copy the dll files OpcNetApi.

You may have to wait a minute for the OPC client to catch up, particularly if there are a LOT of points or tags attached. Then using the Data Source tree on the right hand side, navigate to the correct driver and controller. If the driver tree did not expand the shortcut needs to be re-linked. The driver tree on the right should expose the PLC or controller that shortcut is linked to. On the right you will see the drivers configured in RSLinx and any devices that are communicating via those drivers. If that fails, you might have to restart. This allows you to open the RSLinx Classic app and change settings. RSLinx attempts to run automatically when clients attempt to connect. RSLinx can have only one instance running at a time. Rockwell provides a handy control panel for this. Not only is this required but doing this will make accessing tags easier if you chose a user friendly alias.

This assumes RSLinx is configured to run as a service already. If you come across a SCADA server that is using RSLinx and it is no longer working here are a few troubleshooting steps you can try to get it working again. Typically it is used solely with Rockwell and Allen Bradley products.
