Beispiele Lesen von Einzelparameter und Datenbausteinelementen
Beim Lesen von Einzelparameter und Datenbausteinelementen sollte der
Datentyp der Variablen am Eingang "ValueAdr" zur Datengröße des zu
lesenden Elements passen.
Im folgenden Beispiel wird der SERCOS Parameter "S‑0‑1002.0.0,
SERCOS-Zykluszeit" gelesen.
Es werden alle SERCOS Datenblockelemente des Parameters gelesen.
