Likewise, the interlock function can be set for touch switches and the touch
switch’s operation can be disabled by turning OFF the host’s interlock bit that
controls the touch switch. (See
Controlling PT Operations with Interlock Bits on
page 357 for details.) Check the status of the interlock bits allocated to control
touch switches before inputting numerical values.
Inputting Numeric Values Using the Input Key – Control on the Same Screen
The following describes the basic numeric value input procedure using the input
key – control on the same screen. The explanation of the procedure for inputting
a numeric value into the numeral setting input field assumes that there is only
one input field on the screen.
