Example. To obtain System Volts & System Amps on Node 23h
Packet from master format :
Start at system voltage (0000), request 2 regs (0004 words)
[23][03][0000][0004][CRC(2 bytes)]
Response from slave format ;
[23][03][08][8 bytes of data(2 regs x 4 bytes)] [CRC (2 bytes)]
To set both System Volts and System Amps on Node 23h
Packet from the master format :
Start at system voltage (0000), set 2 regs (0004 words)
[23][10][0000][0004][08][8 bytes of data (2 regs x 4 bytes)]
[CRC (2 bytes)]
Response from slave format :
[23][10][0000][0004][CRC(2 bytes)]
