IntesisBox
Modbus Server - KNX

Functionality

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. It also listens 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 listens 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.
Every one of the mentioned Modbus points is associated to a KNX group address. With this, all the Modbus system
is seen as one more KNX device from the KNX system point of view, with the same configuration and operation
characteristics.
When a change in any Modbus point occurs, a WRITE telegram is sent to the associated Group Address in the KNX
bus. See details in section.
When a telegram is received from a KNX Group address associated to a Modbus point, a message is sent
immediately to the corresponding Modbus device to perform the corresponding action.
