Arduino Mega and HMI WeinView TK6070IQ With Ethernet shield control

Arduino Mega and HMI WeinView TK6070IQ With Ethernet shield controlling a Solar Station Greenhouse. The communication between Arduino and the HMI is done by RS485, serial3, and has connected the W5100 Ethernet Shield, to be able to control everything remote, as IoT. It is measuring temperatures with multiple MAX6675K by SPI communication. The Browser and the HMI are accessing the same RS485 registers, controlling the outputs locally or remote. Also, is possible to control the Vanes and the pumps in Manual or Auto mode, according to the setpoints and the Hysteresys set.
