We have built identical machine, running identical software on MC42's, with the idea of only having one MD4-7 display between these machines as a diagnostics/adjustment tool that is configured as "optional". This would allow for when connecting the display to the MC42, the technician will then be able to interface with the MC42 to adjust parameters.
Also I use the MD4-7 as a programming tool to upload new software onto the machines VIA the display's ethernet port... But what I have encountered is after uploading all the software on both the machines and then plug the display back into the other machine it give a "NO contact MC42" error. Which means I have to upload the software again with the display in place to get contact to that MC42. So each time I want to use the display to configure the other machine I have to do a software upload again from the laptop.
In theory I can't see why this wouldn't work? the display does not store any values, it only displays the parameters that is stored on the MC42's which allows the to technician to adjust those parameters on the MC42 through the MD4-7 display.
I have also tried to upload the software separately on the display only (as an incomplete system), but then it gives "no Contact" error on both machines until I upload the software again with the display in place.
There must be a way to trick the display to think it is connected to the same machine each time it gets swapped around between the 2 machines.
