[mmd604 1]

Looking for a opinions I am currently working in facility that wants to upgrade there current plcs.  currently we have 2 models the a1scpu and fx3u-64m.   The programming is rock solid so I do want to change anything I am just looking for some more modern plcs with ethernet. so we can set up some line control.  I am using GX to interface and with these plcs.  Any opinions would be much appreciated.

I'd recommend to replace both models with FX5U, that has an Ethernet port onboard. Although in this case the program of A1SCPU should be rewritten to match the addressing, variables and commands of FX5U, it's worth it.
