alive15 Posted May 31, 2018 Report Share Posted May 31, 2018 Good afternoon, I've recently received a machine with a Unitronic JZ20-J-T18 and I'm trying to go online with the PLC using the micro-USB port on the side. I don't even have a copy of the program. Right now, I just plug in, open U90, click upload, but it keeps saying no communication? I'm unsure what to do after this step. I've read somewhere that I should be able to program through the micro-USB port? Any help on this would be appreciated, thanks! Quote Link to comment Share on other sites More sharing options...
