Hi, i want to reset the energy meter, can you please send data array.
The energy meter can’t be reset data, need to ask supplier.
when you send the modbus commands.. the last 2 hexidecimal commands on each modbus string don’t seem to coorelate with any known command… is this suppose to be the CRC check high/low byte?
voltage 0x31,0xCA 49 202
current 0x20,0x0B 32 11
power 0x81,0xCB 129 203
energy 0x61,0xCA 97 202
freq 0x80,0x0B 128 11
pf 0xB0,0x08 176 8
Last 2 character is CRC_Low_Byte & CRC_High_Byte

W/salam, laptop.
