RTU Protocal

I'm in the process of writing a master slave driver with visual basic. I would like to know if I could have a copy of your modicon RTU protocal

Thanks so much for your time.

If you have any helpful information please let me know

You can find all informations about Modbus protocol in the PIMBUS300.pdf. (Networks\Modbus)
Unfortunately it is not loadable, now.
I don't know why not.

If you send your email address I will send it to you.
