If you have a node locked license, there is still hope. The 'lease limit' is supposed to be adjustable but at least with Logix 500 and 5, it is not adjustable at this time. If you don't return the borrowed license within the time limit, the license expires and reappears on the server. You can tell the 'client' machine to 'borrow' the license and then return the licenses later right from the list of available licenses. You do not have to have both machines on the network 24/7. The concurrent license for Logix 5000 is only available in the 'Full' version and no others at this time. On the second machine, you can add the server PC as a license source in the FactoryTalk control screen by adding a license directory, but you use the name for the 'directory'. With a concurrent license, when you activate the license on a PC, that PC is a server.
If you don't specify/buy the concurrent one up front, you get node locked. There are two types of licenses: Concurrent, and node locked. There are also countless not so legal methods which is the reason that Rockwell went to the FTA (FactoryTalk Activation) scheme. If you are using the old EVRSI licensing scheme, the only practical (but pain in the rear) way to legally do it is to juggle the license back and forth using EVMOVE and/or carrying the floppy master disk around with you.
