3.3.7.1Busklemmendaten
Die CPU hat über absolute Adressen direkten Zugriff auf die Busklemmendaten. Die Adressierung ist wortweise organisiert und beginnt sowohl bei Eingängen als auch bei Ausgängen mit der Adresse 0. Die entsprechenden Adressen für Bits, Byte und Doppelworte (DWord) sind von den Wortadressen abgeleitet.

Alle Merker sind nullspannungssicher ausgeführt (retain).
3.3.7.4Adressen berechnen
Die Basis zur Berechnung der Adressen ist die Wortadresse (Word).
Bit-Adresse |
Wortadresse .0 bis .15 |
|
Byte-Adresse |
1. |
Byte: 2 x Wortadresse |
|
2. |
Byte: 2 x Wortadresse + 1 |
DWord-Adresse |
unterer Teil: Wortadresse (gerade Zahl) / 2 |
|
|
oberer Teil: Wortadresse (ungerade Zahl) / 2, abgerundet |
