Filtering of the GateWay traffic
The GateWay allows to incorporate a traffic filter into the data forwarding mechanism, that can restrict the traffic
according to individual components of the M-Bus address (ID, Manufacturer, Version, Medium). If, for example,
some specific
”
Medium” or
”
Manufacturer” codes are entered into the filter, only messages with these codes are
cleared for forwarding (or vice-versa their forwarding is forbidden). By entering some characters of the M-Bus ID
into the filter the traffic will be limited only to the series of M-Bus addresses containing the characters. The filter
can be incorporated only through the ”gw.cfg” configuration file (by uploading the file with the filter). A more
detailed description of the filter’s functionality and its settings is given in paragraph
