** Modbus TCP communication not working ** * Is "Modbus TCP" selected in the "Building Management System" menu? * Is the Modbus TCP device and the heat pump in the same network? * Is there an IP address conflict? * Has the heat pump set the IP address manually? IP address should be set manually, because with "DHCP" the IP address can change (e.g. after a power failure). * Was the connection made via a switch, possibly blocking this communication? If so, integrate the Modbus TCP device directly (without a switch).
