Hello,
I'm trying to read analog input from modbus RTU card. Impossible to read all 8 channel.
The instruction I want to send for data reading is:
Send: 01 03 00 00 00 08 44 0C
On the slave modbus module the modbus channel is set:
Reading holding register (code 3) Trigger= cyclic time of cycle 100ms offset 0x0000 length= 8
Where I'm wrong?
Thanks you for your help Fabio
