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
