<p>PURPOSE:To display a large quantity of information with a small number of function keys and at the same time to improve the operability of a controller by assigning a specific function to each function key. CONSTITUTION:A full-dot display 10 is provided on a front panel of a controller and at the same time the functions proper to each screen are assigned to a limited number of function keys KY1-KY10 for each evolution of the screens. Thus the evolution is carried out to various screens necessary for the control operations with operation of the key KY7 having a screen evolving function. Furthermore the evolution is carried out to the tuning screen and the engineering screen of different dimensions with the simultaneous operation of the key KY7 and another specific key. In such a constitution, the control operations are carried out and various parameters are set with operations of a limited number of function keys. Then it is possible to set various parameters while confirming the control operating states with the same display 10 by providing a change key KY6 on a tuning setting screen.</p> |
