Main thing that springs to mind is a cute thing called DEP (data execution prevention) which is only on XP SP2 and as the name suggests, it fights off applications running in areas of memory it feels the apps shouldnt be using. You can try turning off DEP by changing the line in your boot ini to read something like: multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=alwaysoff As opposed to "/NoExecute=optIn". Check with IT that this is not against your policy though. If it helps then you can look at excluding it from DEP. Mine runs at 13,080k. Could your RSLinx on the laptop be doing more? Maybe you have more physical and virtual memory available on your laptop and the apps are taking what they need, whereas on your desktop the apps may be constrained???

I would like to test an ASCII function to talk to a barcode scanner ahead of recieving the actual CLX processor and point i/o cards. Just a quickie to see if anyone has sucessfully used the com port on their PC as the 'Channel 0 Serial Port' and send ASCII data out of it using RSLogix Emulate 5000. When I configure a new controller I am give the option to specify a pc com port as 'Channel 0 Serial Port', so I choose com 1. Com 1 is now unavailable to any other Windoze application and waiving my cursor over the controller looks thus: All seems good, however, using a com port monitoring tool I can see that my Emulator is not sending anything out of the com port. Also if i shutdown the emulator and start it again it looses com port configuration and I have to create a new controller everytime. At this moment I am thinking if this is even a proper function of the emulator...I cant see it documented in any manuals. Thanks for any help.

I have the adapter you are referring to also...it doesnt seem to be doing anything detremental though. I think RSLinx puts it there when you configure the Virtual Backplane driver. Here's what my chasis looks like. I have 3 emulated processors running and 3 topics in RSLinx and all works fine.
