<p>PROBLEM TO BE SOLVED: To enable building up of an easily usable display environment optimal for operators and maintenance workers with simple and efficient work by performing a control to store information on a default display pattern or information on a display pattern before altered. SOLUTION: For altering of display pattern information, as basic processing procedure, a central processing section 1 reads currently used display pattern information from a display pattern information holding area 24 of a memory section 2 after receiving a command to alter the display pattern information from an input part 4 and retreats the information into a preceding display pattern information holding area 25 of the memory section 2. Thereafter, the central processing section 1 alters the information of the display pattern information holding area 24 according to an input from the input part 4 and an input is sent from the input part 4 to define the display pattern. This enables building of an easily usable display environment optimal for operators and maintenance workers with simple and efficient work.</p> |
