Subject: Re: Cobra on/off monitor

Hallo Bernhard,

das Signal ist online verfuegbar ueber IP Multicasts. Du musst nur das
angehaengte Programm kompilieren und ausfuehren, es zeigt Dir jede
Sekunde den Strom im Haupt- und Hilfsmagnet an. Leider zeichnen wir
momentan diese Werte noch nicht permanent auf, das wird erst naechstes
Jahr kommen.

Gruss,

  Stefan
