Integration of KNX and Modbus using IntesisBox Modbus Server - KNX gateway
The integration operation is as follow:
From the KNX system point of view, in the start-up process of the gateway and also after a
detection of a KNX bus reset, the gateway polls the KNX signals configured to be updated in
this situation and maintain the received values in memory to be served to the Modbus
system when requested. Also listen for any KNX telegram related to the internal points
configured in it and acts accordingly to the configuration of the related point.
From the Modbus system point of view, after the start up process, the gateway listen for
any read or write request, and serves any read request or performs any writing request of
its internal points received from Modbus system. The values received from Modbus become
available to be read by the KNX system and vice-versa.
If a signal has been configured as of type "T" Transmit (in the KNX part), any new value for
the signal coming from the Modbus system is notified to the KNX system with the
corresponding telegram.
When, from the KNX system, a signal is changed (written from any other KNX device for
example), the new value is updated in the gateway's memory, ready to be served to
Modbus when requested.
