Video: How to configure the PM800 series clock via writing to registers using Modbus commands?
Issue
Configuring the time and date on the PM800 series meters through RS-485 when Ethernet is not available
Product Line
PM800 series
Environment
RS-485 communications, Modbus register read/write
Resolution
The date and time are stored in three-register compressed format. Each of the three registers contain a high and low byte value to represent the date and time in hexadecimal. For the synchronization, the command value is written in register 8000 and the values are in registers 8001, 8002, and 8003. The command used to initiate the change in register 8000 is 1311.

| Hexidemical Value | Hi Byte | Lo Byte |
| 0119 | 01 = month | 19 = day |
| 640B | 64 = year | 0B = hour |
| 063B | 06 = minute | 3B = seconds |
