KNX TP-1 (EIB) system and vice-versa. For this, IntesisBox acts as a Modbus TCP server or Modbus RTU slave device in its Modbus interface, allowing read/write points from the Modbus client device(s), and offering this point's values through its KNX interface, acting in the KNX system as one more KNX device of the system.
2 KNX interface In this section, a common description for all IntesisBox KNX series gateways is given from the point of view of KNX system, which is called from now on external system. The Modbus system is also called from now on internal system.
Description IntesisBox acts as a slave device in its Modbus interface, this interface can be the Ethernet port (if using Modbus TCP), or the EIA232/EIA485 ports (if using Modbus RTU). To access the points and resources of the IntesisBox from a Modbus master device, you must specify as Modbus register addresses, those configured inside IntesisBox corresponding to KNX signals.
Every point defined in the gateway has the Modbus Format, Point and R/W features associated to it that can be configured. These features are explained in section 5.2.4. Each point defined in IntesisBox has the following Modbus features associated to it: Feature...
Connect the communication cable coming from the KNX network hub, or switch, to the ETH port (Figure above) of IntesisBox. In case there is no response from the KNX installation, or KNX devices, to the frames sent by IntesisBox, check that they are operative and reachable from the network connection used by IntesisBox.
It is necessary to have a KNX installation, device or interface operative and well connected to the corresponding KNX port of IntesisBox and a Modbus RTU slave or Modbus TCP client connected to their corresponding ports as well. Connectors, connection cables, PC to use the configuration tool and other auxiliary material, if needed, are not supplied by Intesis Software SLU for this standard integration.
5.2.4 Signals All available objects, Object Instances, its corresponding Modbus register and other main parmaters, are listed in the signals tab. More information on each parameter and how to configure it can be found in the IntesisBox MAPS user manual.
If NO is selected, remember that the file with the project needs to be generated before the IntesisBox starts to work as expected. 3.- Press the Send File button to send the file to the IntesisBox device. The process of file transmission can be monitored in the IntesisBox Communication Console window. IntesisBox will reboot automatically once the new configuration is loaded.
Port B of IntesisBox (More details in section 0). 5. Power up IntesisBox. The supply voltage can be 9 to 30 Vdc or just 24 Vac. Take care of the polarity of the supply voltage applied.
