Hello everyone, I'm a beginner to using PLC's and I'm having some trouble connecting to my PLC. I don't know if my PLC is bad, cable is bad (pretty sure its good), or my ports are messed up. I have no experience and I am using the U90 ladder program.
In U90, when I go to Controller>Operating System or the 2nd way I've been going about it Controller>M90 OPLC Settings, I am just trying to establish connection to my computer to the PLC. I keep getting errors on failing to connect to the COM port.
There is another post on here talking about how my PLC (JZ20-R31) has a USB mini port on the side. I have the driver for it downloaded as well as the driver that comes with the 'Install Driver' button in U90. I've never really messed around with ports before, so I'm not sure what I'm supposed to be looking for. Some other online stuff said to try Device manager>Add legacy Hardware> .... Could the issue be not choosing the right options after I choose "Ports COM & LPT "?
Because no matter what driver I do, I can confirm that the COM# in Device manager matches the one in U90 ladder and I still can't get the connection.
I have a windows 10, HP Pavillion 17 notebook.
Can you provide any tips for a rookie?
