Configuration:
• If there is not a DHCP server on the network, attribute a static IP address, its mask and the gateway if necessary to the Box
(Discuss with the building’s IT manager).
• If there is a DHCP server on the network, the address is automatically assigned.
Information to retrieve in preparation for the configuration:
• For each device that communicates in Modbus IP
–From the BMS software, perform an extract of the available properties: list the data types provided by the different devices
to which the BMS has access.
–If it is impossible to retrieve this information, recuperate the IP address and TCP port (and if needed, for some devices, the
slave address (Slave ID), the brand, and model of the equipment, and extra identifying information. This information is
necessary for the installation configuration and to retrieve data.
• In the case of a BACnet IP network
–Write down the BACnet port of the network. This information will be necessary for the installation configuration and to
retrieve data.
