Hello everyone, I am facing a challenge with a Modicon M172 PLC (HVAC PLC) as I do not have the original source code. I am looking to make modifications to the code, but I have heard that it is not as simple as uploading the program like with an AB PLC. Can I still go online with the PLC and make live edits without the original source code? Has anyone encountered this issue before?
Yes, it is essential to have the source code at all times. For more information, please visit the official website.
I greatly appreciate your assistance!
Hey there, I've run into this situation before with Modicon PLCs. Unfortunately, unlike AB PLCs, you indeed will not be able to make live edits without the original source code. The Modicon PLCs require the original code for source modification, so you may need to reach out to the person or company who implemented the system to get the original files. If that's not possible, you might have to reverse engineer the PLC logic, which can be quite tricky. On a brighter note, if you're just looking to troubleshoot or monitor the system, you can still go online and do that without the original source code. Hope that helps!
Hey there! I've dealt with a similar issue before, and unfortunately, with the Modicon M172 you can't make live edits without the original source code. Unlike some other PLCs, changes and modifications here require the original source code. My suggestion would be to reach out to the equipment manufacturer or your PLC provider. They might be able to support you in accessing the original code or offering viable solutions.
Hi there! I can understand your frustration; working without the original source code can be tricky. With Modicon PLCs, while you can often access the program to monitor and diagnose, making live edits can be limited without the source code. You might be able to use tools like Unity Pro to connect and potentially adjust parameters online, but modifying the logic itself usually requires the full project file. Have you tried reaching out to the previous programmer or looking for documentation? It might also be worth checking if the PLC has a backup of the code saved somewhere! Good luck!
Hi there! I understand your frustration—working with a Modicon M172 PLC without the original source code can definitely be tricky. Unfortunately, unlike Allen-Bradley PLCs, the Modicon series usually requires you to have the source code to make meaningful edits. While you can connect online and view the existing program, making live changes would typically be limited or not feasible. If you haven’t already, consider reaching out to whoever originally programmed it or looking into backup or export options. Sometimes, there are software tools or even third-party resources that can help you extract some usable code, so it might be worth exploring those avenues too! Good luck!
