Mitsubishi FX thru LabVIEW

[ivelson]

Hi everyone.

I have an old mitsubishi PLC model (FX1s-24MR). I have a task to control and monitor its inputs/outputs using LabVIEW. I had successfuly done this using IA OPC server. But i also need to communicate via Serial RS-232.

Now i am in the verge of studying its command protocols, but then I am hoping if someone there has already have a LV program for communicating Mitsubishi FX via RS-232, it will be greatly appreciated (it will save my time a lot)!

thanks in advance!

There is a blog that introduce PLC communicate via Serial RS-232. It's Chinese, so I am not sure your computer can display or not. If yes, you can press "回應" to ask source code. Wish this can help you.

Hi Ancle,

I cannot access your provided link (maybe because our private network is highly protected, so they blocked such sites like this).

Hi ivel,

There is a source code file. However, it named in Chinese, but I think when you see source code you know how to use it. Good luck.

Hi Ancle,

Thank you so much. I had a chinese friend here so we can handle this part. just another question, Can I communicate to Mitsubishi PLC with having the MX component? have you tried this before?

[Ancle]

No, I haven't.

whew... it seems like the source code provided was not following the command protocol of my FX1s mitsubishi (FX2N neither!) based on the mitsubishi manual. its lacks many things like station #, PLC #, command protocols, etc.

I didn't have many experinces about PLC and the source code is written by another person. In his blog, he said it works fine in FX2N, so I think you may modify the source code to meet what you need.

as far as I knew, the FX2N and FX1s share the same command protocols (based on what i read in the manual).

I really appreciate your great effort on this. thanks anyway. as of now, I kept studying its command protocol.

Hi ivel,

If your friend can read Chinese. The attached file is blog's documents. Good luck.
