Process Gateway IEC870SL

Process Gateway IEC870SL

Hy!
Ich verwende das Process-Gateway mit dem Modul IEC870SL.
Protocol 870-104.
Zum test habe ich eine interne-Variable "VAR1" angelegt.
Nach dem Start des Gateways meldet der Master eine Verbindung.
Soweit ich weiß sollte nun bei „nderung des Wertes der Variable eine übertragung vom Slave zum Master erfolgen. Daher habe ich VAR1 getoggelt, jedoch ohne Reaktion.
Ich habe mit einem Netzwerk-Sniffer die Kommunikation überprüft und festgestellt dass nur eine Life-Anfrage zwischen Master und Slave ausgetauscht wird.
Daher meine Frage ob man die Kommunikation vielleicht initialisieren/starten muß??
Hat jemand Erfahrung damit??
