The main new features of this preview are:

Hello Factory I/O team,

I tested the preview edition of 2.4.4. It is working good.

The new version works flawlessly with RSLinx OPC sever – which is great.

The only small bug that I found is that when I try to save and re-open factory I/O file that is configured to use RSLinx OPC Server, I get the following message.

The good news is that the file works perfectly without any problem. The bug is mostly cosmetic: an error is thrown while there is no error.

I am interested in using factory io with the studio 5000 package which I have installed on my computer. I have the appropriate version of emulate installed as well. I have the OEM version of RS linx as well. I know that this may be a bit to ask, but I would like to ask if there is some sort of procedure in order to get this to work using the OPC server driver. I have been told that it will work, but I have yet to get things to work. I have installed the factory io version 2.4 as well.
Thanks, and best regards.
