In addition to the built-in Ethernet interface, the data logger also has an RS485 interface available to the user. This can be addressed via Modbus RTU. The user can communicate with the climate data logger via Modbus TCP / IP, HTTP, FTP via the Ethernet interface. A web and FTP server as well as a DHCP and SMTP client complete the functionality of the data logger’s network interface.
