On the main mask we find a reproduction of the classic touch panel screen, the difference are the changes that are performed using
the arrow keys.You can increase or decrease the values by one unit clicking the single-arrow key, otherwise you can increase or
decrease them by several units clicking the double-arrow key. Clicking on the middle button you can turn off directly post-heat ,fans,
or timer. Changes are automatically saved after 5 seconds. The writing of the Holding Registers via modbus is disabled for 60 seconds
after each change made through the Web server. In order for the webpage to be continuously updated, click the "refresh on" key:
the writing will become "refresh off", so the page will be updated every five seconds. Should the machine be equipped with a post-he-
ating system, also the desired set-point temperature will be displayed: When you click the Menu icon, a list of available choices will
appear, which can be selected by the arrow keys. For the description of the several menus, refer to the previous items.
Configuration parameters, set-points, and input signals, statuses and alarms are in format word 16 Bit and are accessible as:
BXX is the XXth bit of a word (XX is a value comprised between 00 and 15). R indicates the word is just readable, while R/W indicates
the word is readable and writable. R/W values are reset to the values set by the Web server or if the register access time is exceeded
or the unit is switched off. The most significant bit is characterized by the highest value: for instance, between B00 and B15 the latter is
the most significant one. Standard addressing (Gould) is zero based in the protocol message. That means that if you want to read the
first register, holding register 1, the starting register field in the message will be 0000. Below the modus table
