APPENDIX A
A.3SYNCHRONIZATION
To synchronize the date and time of a relay we use a command with the following characteristics
The command is executed in broadcast mode (relay address =
1.
Date and time are included in the message. The date and time format length is 6 bytes
2.
No answer is expected from the relay
3.
FIELD
Relay address
Function
Beginning address
Number of registers
Number of bytes
Value of the registers
CRC

Example :

The following date and time will be sent: 31st of May 1999, at 10.01:04.224, this is 107,690,464,224 milliseconds from the
base date/time:
107,690,464,224 Decimal = 00 19 12 DA 13 E0 Hexadecimal.
Reordering to send the lowest weight byte first: E0 13 DA 12 19 00
