When using the buttons as buttons switches, makeyour selections based on the screen status.2.The operation buttons can be used for ZEN operations, suchas menu selections, regardless of whether or not buttonswitches (B) are being used.Using Button Switches (B)Section 3-13When a button is pressed for ZEN operations, the buttonswitch (B) also turns ON. Make sure that the system will notbe affected by this before pressing buttons.73SECTION 4Special FunctionsThis section describes how to protect ladder programs, stabilize inputs, make LCD screenadjustments, and make summer time settings.4-1Protecting Programs.
