I programmed several Micrologix 1200 (all the same version ) with RSLogix500 (4.00.00.60)
But the last one gives me an error message when trying to go online:
Decompiler -> Unknown error.
I see the ML1200 in RSLinx and RSLogix500, the only difference is that is "untitled" (see attachement). Could that be the issue?
I also toggled the COM push button, with noo result.
Any help would be appreciated.
I already browsed older topics on this site, but with no result.
