Unlike RSLinx Enterprise software, it provides a dow

3、nload path for the various RSLogix software packages to the matching controller.4；.Understanding RSLinx Software The information being served to FactoryTalk View SE Servers or FactoryTalk View SE Clients is local. The RSLinx data server is installed on the same computer as the FactoryTalk View Se Se

4、rver.Use RSLinx Classic when:You do not need to install an activation key to make RSLinx Classic work, provided you run RSLinx Classic on the same computer as the FactoryTalk View SE Server.5；.Understanding RSLinx Software If the information is being served to third-party OPC client, for example, a

5、FactoryTalk View SE Client. If the RSLinx data server is installed on a computer separate from the FactoryTalk View SE Server. You might do this for performance reasons, or to locate the OPC server physically close to the process generating data.You must use an RSLinx activation key for RSLinx Gatew
