Arduino as Ethernet Server - Simple ModBus

[Diverdke]

Group,

I have an Arduino with the Ethernet shield communicating with LWCVI via the standard TCP/IP library.  I will eventually create a small ModBus (TCP) implementation with this system to retrieve analog data and send commands to the Arduino.  If you are interested in this technology, drop me a reply and I will post code/examples/etc.  Suggestions welcomed.

Thanks, David Eaton

Could you show me a working example. Which libraries to use on Arduino side, etc.

Hello Layosh, the OP did not connect on the forums since 2015: I don't suppose you can get any reply from him.

I did not pay attention to that, in fact I was absent for a while, programming was not the priority of my tasks. But it is changing again, 🙂

I was playing with networking a bit, but microcontrollers, instrumentation and secure logging  are the new target.
