Troubleshooting CJ1M Connection Issue with CX-Programmer 9.82

Question:

Greetings everyone. I have a CJ1M CPU13 that we are attempting to establish communication with using a CS1W-CN226 cable and a USB-Serial converter. We have one computer running version 9.81 and another running version 9.82 of CX-Programmer. The computer with version 9.81 is able to connect to the CJ1M without any issues, but encounters problems with certain USB connections. The issue arose when we upgraded one of the computers to CX-Programmer 9.82. Despite using the same connection settings as the computer running version 9.81, it is unable to establish a connection with the CJ1M. As a newbie to CX-Programmer, I am wondering if there is a misconfiguration in the settings causing this issue.

When working on the same CX Programmer project, it is important to ensure that the serial settings match those saved in the project. Be sure to choose the right COM port, as this may vary. If you are confident in your COM port selection but still experiencing issues, it could be due to USB to Serial converter problems on a Windows system. In such cases, a helpful troubleshooting step is to conduct a loop back test. Simply short pins 2 and 3, then enter characters using a terminal emulator such as RealTerm. This can help diagnose and address any serial communication issues you may be encountering.

Hey there! It certainly sounds like you're encountering a frustrating issue. In my experience, some newer versions of software like CX-Programmer can have compatibility problems. Even if you're using the same settings as before, the changes in the software update itself may not gel well with your current equipment or systems. It might be a good idea to check whether there are any known issues with CX-Programmer 9.82 connecting to CJ1M. If this turns out to be the case, you might want to consider reverting back to version 9.81, or hoping for a fix in a future software patch. Hope this insight helps!

Hello! It seems like you're facing a compatibility issue here. The problem might be due to the newer version of CX-Programmer requiring different settings or having a compatibility issue with certain USB-Serial converters. I suggest you first recheck your configuration settings to see if anything might be overlooked. If the problem persists, check the release notes for the newer version of CX-Programmer. They often list any known issues and, sometimes, workarounds. If no luck, reaching out to Omron's support could be helpful. They may have had similar cases and can guide you through.

It sounds like you're dealing with a tricky compatibility issue between the different versions of CX-Programmer and the USB-Serial converter. Sometimes, minor configuration changes might be needed after an upgrade, like checking the COM port settings or ensuring that the correct driver is installed for your USB converter. Another thing to consider is whether the upgrade has changed any default settings or introduced any bugs. Maybe try creating a new project in 9.82 and importing the settings from the 9.81 project to see if that helps. Good luck!

It sounds like a frustrating situation! Given that the connection works perfectly with version 9.81, I’d first recommend double-checking the USB-Serial converter settings on the 9.82 machine, as sometimes these can default to different parameters after an upgrade. Make sure the baud rate, parity, and other configurations match exactly with what you have on the other computer. Also, check if there are any driver updates for your USB-Serial converter that might resolve compatibility issues with the newer CX-Programmer version. If those settings are all correct, it might be worth looking into any release notes or known issues with 9.82 that could relate to communication. Good luck!
