Application Example
Task:
On a camping site, 64 current values are to be detected and used on a PC for the issue of
invoices.
Solution:
The counter modules G4420 7401 are built into the local power cabinets. Four Dupline energy
Energy Kwh meters supply one G4420 7401 with the corresponding count-pulses.
The Mastergenerator is configured to 8 digits, occupying addresses from B1 to F8.
Through the DDE server software, an application is built in a spread-sheet software, where the
individual counters may be reset, when new guests arrive.
The voltage of the individual power outlet is turned on from the PC through a relay module. Free
channels are used for this purpose.
The applied Mastergenerator can, of course, also perform additional automation functions.
