KEYS FOR SCREEN – The buttons shown in the lower right hand side of the screen dialog are for editing the
function keys for that screen. This would be considered local programming for function keys, effective only for the
current screen number. Global programming must be performed by creating a Function Key screen, or using the
Edit menu, Function Keys.
Red keys have not been programmed yet. Green keys have been programmed.
Double click on the red key to program, or green keys to change programming. The following Editing Key
screens will be displayed. The first dialog box below will be displayed if a register tag is chosen in the register
list box. Choosing a coil tag will display dialog box at the bottom.
Bits can be controlled in several ways. Turn Off and Turn On functions force set the bit to the 0 or 1 position.
Toggle alternates the bit between 1 and 0 as the function key is pressed. Hold Off and Hold On set the bit to a 0 or a
1 as long as the function key is held (momentary switch).
