Allen Bradley 1747-UIC DH485 Issues
craigrichards posted a topic in Allen Bradley / Rockwell AutomationHi there, I am having issues connecting my computer to our SLC 5/02. We have a genuine Allen Bradley 1747-UIC USB to DH485 adaptor, I have read into it a fair bit and have tried many different things. I have removed pin 3 configurations from the ethernet (DH485) as advised previously.. I have tried many drivers to get it to work to no prevail. I cant even change the CPU over to a 5/03 as I cant guarantee the program we have a copy of is the exact one in the CPU, therefore I cant just change to a different unit and establish comms that way. Does anyone have a step by step guide to connecting the 1747-UIC to the PLC? Many youtube clips dont seem to work for me like they do in the videos. Thanks a lot in advance if you can help!
