Basic HMI with RSLINX Classic Lite

Hi,
I’m working through the challenges but I don’t have Studio 5000. Is it possible to get a free/demo HMI that can work with RSLINX Classic Lite?
I’ve noticed that use of DDE and OPC is restricted with the Lite version of RSLINX. Is there any way to practice some visualisation with free or demo software?

Thanks,

Chris
