Dear Mr.
Thank you for your help, yes I have link between the TL server and the PLC, I started first the TL server, then the Excel and last the TriExceLink, I test the IR* and it returns the ID (01).
When I use the 5 Macros of the "TestMacro" file that come with the TriExceLink CD I can read Variables but just when I run the macro and it isn't refresh autmatically I suppose it is correct, but when I try to do it without the TestMacro, just pressing the "Run" button don't work, it is the way the ExceLink work?
John
