I have a question about my Network Engineering Stack Exchange post: What's the role of Negative Acknowledge (NAK) in Modbus?

There's no tag referring to Modbus, and I'm unable to create it because I'm still a beginner in this community. I used the tag troubleshooting, which is not very accurate in this case. What should I do?

You will not find a tag for Modbus. On a network, Modbus rides on top of TCP or UDP, meaning is is a protocol above OSI layer-4, which, unfortunately, means it is off-topic on Network Engineering. Even the title of the link you posted claims its an application protocol, not a network protocol.

The What topics can I ask about here? section of the Help Center has a list of topics that are allowed, and a list of topic that are not allowed.
