5. Radio modules
The EDC wireless M-Bus radio modules are
available in T-(standard), optionally in S- or C-
mode. Various data telegrams are available. The
modules operate unidirectional and usually send
every 20 seconds. Special versions possible.
Setting parameters:
■
Current status of the roller counter (register)
■
The water meter number related to the EDC
module
■
Pulse value of the modulator disc
■
Resetting of the status bits (tampering, error)
■
Resetting of all logger values (in case of re-
placement of the water meter and further use
of the EDC module)
Activation performs automatically, as soon as the
function "pulse enabled" is activated and the EDC
module scans 30 pulses from the register. The
current status of the roller counter is programma-
ble by means of the optical head using the front-
mounted optical interface of the EDC module.
The ZENNER PC-software GlobalMeterManager
(GMM) is required for programming. The configu-
ration is made by means of the GMM licence, the
universal interface MinoConnectRadio with Blue-
tooth interface and the specific ZENNER infrared
optohead IrCombiHead.
