5.2.3 Beispiel für die Messwertübertragung
Master: Request Data
Byte: SD DA
Value: 0x10 x
DA = Destination address = slave address = 0x7E
SA = Source address = master address = 0x01
FCS = Checksum = 0x7E+0x01+0x43 = 0xC2
Slave: Response Data
Byte: SD LE
Value: 0x68 0x13
LE = Length = 16 data bytes + 3 bytes (DA, SA, FC) = 19 bytes = 0x13
DA = Destination address = master address = 0x01
SA = Source address = slave address = 0x7E
FCS = Checksum = 0x01 + 0x7E + ....
