In our latest “Tech Files” installment, we look at a potential issue on using RSLinx Classic Single Node and OEM versions on 64-bit machines.
- After upgrading to a 64-bit machine and recompiling custom application from 32 to 64-bit, application is not able to communicate to RSLinx Classic OEM.
- 64-bit application will not communicate and work with RSLinx Classic OEM.
RSLinx Classic is a 32-bit application and will operate on a 64-bit edition of Windows; however, the RSLinx Classic Single Node and OEM activations may not operate properly if there is a Windows 64-bit application running on the same computer. Windows 64-bit operating system runs the 32-bit and 64-bit application in different processes which means RSLinx Classic Single Node and OEM sees the 64-bit application as running remotely. This prevents the 64-bit application from using the OPC interface; therefore, RSLinx Classic Single Node and OEM will not operate as expected on the same machine that hosts a 64-bit application.
Use one of the following solutions:
- Create / compile custom application as 32-bit application
- Use RSLinx Classic Gateway (additional licence required for this product)
- Use FactoryTalk Gateway (additional licence required for this product)
