C_R_PLC Posted February 19, 2019 Report Share Posted February 19, 2019 After downloading my program onto the PLC I'm working with I had to revise it a few weeks later and went back to download the new version, but now it's giving me a comms error no matter what I try and do to fix it. I've tried every baud rate, multiple ports on my PC, checked jumpers (which from what I can see are correct but always seem to be a point of error for me), and tried a blank program as opposed to the one I want to download. Connection is PC USB -> MJ 10-22-CA25 adapter, all hardware is the same as the initial upload. Quote Link to comment Share on other sites More sharing options...
