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
counters supply one G4420 7401 with the corresponding impulses. The Master Generator is
configured for Counter setup through entry of the counter ranges. A data entry software avail-
able through a DDE interface reads out the values via the DDEServer and resets the counter
value when a new guest arrives.
The voltage of the individual power outlet is turned on from the PC through a relay module
(software DP-Camp). Free channels are used for this purpose.
The applied Master Generator can, of course, also perform additional automation functions.
