You can delete the Harmony files with 2 methods: Automatic and Manual.

(If you don't restart RSLinx before you perform the Restore, you will receive an error).

After you are finished deleting the Harmony Files, you will need to Re-Start RSLinx.

Enter a filename and a location, and click Save.

Go to Start->Programs->Rockwell Software->RSLinx->RSLinx Classic Backup Restore Utility.

You may want to backup the configuration of the drivers if you have many drivers or various configurations.

Warning: When RSLinx Classic is performing as a OPC/DDE Server for an application, delete the Harmony files only when the application is not in operation.

For more information about the Harmony files, please refer to 5765 - Description of Harmony They are cache files of RSLinx and will be automatically recreated when RSLinx Classic is reopened.

Click the run button when you are ready.You can delete Harmony files if they are corrupt.

In this example we are trying to connect to register O0:0 using access path ML1500 defined in RSLinx, therefore the item name would be O0:0. Set the Server Name to be RSLinx OPC Server, and the Item Name in the form Item.

This VI can connect to any OPC Server using DataSocket connection.

Launch LabVIEW and open opc.llb in the.

The following is a brief example of how to connect to RSLinx OPC Server from LabVIEW using our example VI. To learn more about DataSocket, visit Integrating the Internet into The API provides an interface for different data types, converting the data into a stream of bytes that can be sent across a network via TCP/IP. DataSockets have an OPC layer, allowing you to read and write to an OPC Server from LabVIEW (or LabWindows/CVI).ĭataSocket is a technology based on TCP/IP composed of two elements: the DataSocket API and the DataSocket server. LabVIEW itself is not an OPC Client, but it can be used to communicate to OPC Servers through the DataSocket VIs.

The cable model number used was 1761-CBL-PM02. This document was created using RSLinx 2.20.01.107.01, Allen Bradley MicroLogix 1500 PLC, ServerExplorer 2.4.1, Lookout 4.5 and the LabVIEW DSC module 6.0.2.

If you decide to use the LabVIEW DDE VIs, then you need to have the full version of RSLinx. The drawback of DDE connection is that it is slower than OPC. The DDE server is only available for Rockwell Automation DDE clients in the OEM version. Other Allen Bradley PLCs can be used on the OPC server by manually adding the addresses to be seen.Īnother mechanism of communication between applications and RSLinx is through the DDE server that comes with RSLinx. RSLinx 2.0 to 2.20 OPC servers only support the browsing capability on Control Logix 5000 series PLCs. RSLinx OPC server is an in-process type of server, which means that you have to load a DLL to communicate with it. The OPC server is available only with the OEM version or the full version, so the lite version of RSLinx does not have the OPC Server included. Rockwell Automation RSLinx 2.10 is an OPC server, meaning that any OPC Client should be able to exchange data with this server. This version has been upgraded to version 2.20. Rockwell Automation developed their own OPC Server in version 2.0 of RSLinx. Any OPC client, such as Lookout, BridgeVIEW, or other packages on the market, can connect to this server. With the release of Industrial Automation Server CD 1.1, this server became an OPC server. The NI Industrial Automation Servers CD has an Allen Bradley (RSLinx) driver that can communicate with RSLinx through a dynamic link library (DLL).
