Y<br />

Specifies the position of the upper left corner along the Y axis (interval from the upper display<br />

margin). Values for these parameters begin with 0 on the upper margin and increase to the<br />

height of the display minus one pixel (on the lower margin).<br />

Possible Settings for Full<br />

Graphic Displays<br />

Possible Settings for Text<br />

and Semi−Graphic<br />

Displays<br />

The field can be placed freely in the display. Therefore, Y can<br />

be set from 0 to the height of the display minus the height of the<br />

field in pixels.<br />

On text and semi−graphic displays, such as those which can be<br />

connected to the C130 CAN controller, fields can only be placed<br />

evenly on every eighth Y−coordinate (Y = 0, 8, 16, 24, etc.).<br />

Possible Values Bit 0 If 1, the input field is invisible.<br />

Bit 14 Is set to 1 while the input field has the focus (is<br />

highlighted). The focus determines which input field is to<br />

accept input from the operator panel.<br />

If the input field loses the focus, then this bit is reset back<br />

to 0.<br />

Bit 15 Is set to 1 while the input field is activated (the value in the<br />

input field is being edited). It will be set back to 0 after the<br />

input has been completed or cancelled.<br />

All other bits are reserved.<br />
