Redes Posted February 22 Report Share Posted February 22 Hello. I have JZ20-J-R31 unit. I want to program it, but it does not seem to connect to PC. I have mini USB to standart USB cable. I put cable into PLC and into PC, no sound, no reaction. Tried to install drivers, searched forum, nothing helps. But i have question, no one asked yet i think, do this PLC have to be powered on when programing, i mean do i need to put power to V+ V0 (24vdc) terminals to program it?Or it should work without power? (From usb port power?) thank you very much Quote Link to comment Share on other sites More sharing options...
