I need a Modbus RTU Overview


Thread Starter

Nick Jacobi


I did a brief search in this forum but didn't find quite what I'm looking for.

I need an overview of Modbus RTU and what sets it apart from Modbus/TCP or any other Modbus protocol for that matter.

I've scoured the internet but came up pretty much empty except for a few lines that mention that RTU is in Binary as opposed to ASCII. I'm looking for more depth than that.

So if you've found a good overview somewhere on the net, please share. Any help would be appreciated.

You can find the documentation for MODBUS RTU in the Schneider website. Or I can send you docs for the MODBUS RTU provided youe supply me with your email address.


Thanks everybody for the replies, this should be more than enough information to go on. If there's anything else I need, I'll be sure to come back. I'm surprised at the amount of help I've received about this.
