Help with Modbus Hold and Store


Thread Starter


A special Hello to everybody.
I'm a student and I need your help to prepare a rapid software\solution (I hope free) for my porpouses. I have a modular group (Twido) that work in slave modality, and an ethernet block to link the PLC with my PC.

I'm able to verify the correct functions of the PLC by a modbus master simulator that are free on the net, but I have no solution to store the data. My intention is to preserve the data in a database, everytime that I want. Imagine that I have a toolmachine that work, a PLC near the machine, how i save my modbus flow?
