Modbus Memory Map - S&P CTB ECOWATT Instrucciones De Uso

MODBUS message
Direction Function
8 bits 8 bits
Format for each byte in RTU mode is:
• System codes: 8–bit binary
• Bits per Byte: 1 bit to START (start)
8 bits for data, the most signifi cant bit is sent fi rst
1 bit for parity (Even parity is required)
1 bit for STOP (end)
