I am an industrial controls engineer. I work with PLC hardware and software.
I am wondering if questions about PLC programming software are on-topic here. For example, I was thinking about asking a question about determining which version of Rockwell Software is required to open a particular .ACD file, which is a project file for Rockwell/Allen-Bradley PLC. (I figured out the answer myself, so I would probably self-answer this question.)
The question isn't about programming, exactly, so I doubt it would be on-topic on Stack Overflow. It is definitely related to Electrical Engineering, although I rarely see any questions of this type on this site. The question certainly isn't hardware-related.
I personally would love to see these types of questions here, but I'm curious how the current users of the site feel about it.
If it would not be a good fit here, would it perhaps be more welcome at Engineering.SE? Does that site handle Electrical Engineering topics that are related to industrial controls?
