2.2.4.1 Voorbeeld checksum berekening
Om data van de PMIX35 te ontvangen moet een request worden verstuurd naar de PMIX35.
Deze request is beschreven in
Tabel 2 6: Bericht: RQ (Data Request) en ziet er als volgt uit:
$>9000RQcs#
Om de checksum "cs" te berekenen moeten de hexadecimale waarden van alle voorgaande karakters hexadecimaal bij elkaar
worden opgeteld. Deze waarden kan men vinden in onderstaande ASCII tabel:
Met de waarden uit de tabel gaat de berekening als volgt:
Karakter: $>9000RQ
Hex waarde: 24 + 3E + 39 + 30 + 30 + 30 + 52 + 51 = 1CE
cs: =CE
Gebruik alleen de laatste 2 hexadecimale getallen voor de checksum.
Een Data Request ziet er als volgt uit:
$>9000RQCE#
Voorbeelden van antwoorden die men van de PMIX35 kan verwachten:
$<900029#
$<9000ND001B#
(Geen Module noise detected)
$<9000NI001687# (Netwerk Impedantie is: 1,6 Ohm)
Bij ontvangen data komen ook de LR en LE data types mee.
