I’m trying to read the time and date over modbus from a PM800 power meter.
Here is the template the manual gives.
Templates
Date/Time
*Note: Date format is a 3 (6-byte) register compressed format. (Year 2001 is represented as 101 in the year byte.)
Register 0:Hi Byte = Month (1 – 12) ; Register 0:Lo Byte = Day (1 – 31)
Register 1:Hi Byte = Year (0 – 199) ; Register 1:Lo Byte = Hour (0 – 23)
Register 2:Hi Byte = Minute (0 – 59) ; Register 2:Lo Byte = Second (0 –59)
Register 3: = Millisecond (0 – 999)
I have hit a blank with this. Please help.
