Modbus TCP multiple read and writes
I have been using tom's Modbus TCP blog article to develop a local Modbus TCP network with 4 servers and 1 client that displays data and gets setpoints on a Nextion screen, and it works fine but quite slow when the client reads individually input registers (or writes individually holding registers, but this is a lesser problem), so I have been looking for a solution to read multiple input registers on Modbus TCP and came across requestFrom() and read(), but no luck to day to get them to read the 45 input registers every server leaves at the disposal of the client.
Any ideas welcome, I'll keep digging and keep you posted if I find something.
