Global Window Setup - Digital Equipment Pro-face GP2000 Series User Manual

Chapter 6 - Initializing the GP

6.3.3 Global Window Setup

The GP unit can display three screens at any one time, one Global Window and two
Local Windows. The Global Window is common to all the display screens. The Local
Window displays exclusively on the corresponding base screen. The GLOBAL WIN-
DOW SETUP is described here.
GLOBAL WINDOW
There are two options here: Use and Do Not Use. If you select Do Not Use, ignore
the items described below. Selecting Use enables these options.
GLOBAL WINDOW ACCESS
Use this feature to designate whether a value used is DIRECT or INDIRECT, i.e. the
REGISTRATION NO. and the LOCATION values.
When set as Direct, the REGISTRATION NO. and LOCATION selections are fixed to the
values entered here.
When set to Indirect, the WINDOW REG. NO.'s word address, as prepared in the
System Area, is a variable. This means it can have the REGISTRATION NO. written to it
and, as a result, multiple window screens can be used as Global windows. You can use
this method to adjust the Global window position by writing the X,Y coordinates to the
SYSTEM AREA's LOCATION word addresses.
DATA FORMAT
Setup whether the REGISTRATION NO. and the LOCATION values are BIN or
BCD values. This field is related only to indirect values.
REGISTRATION NO. (1-256)
Enter the Window Screen Number used by the Global Window. This field is enabled
only when GLOBAL WINDOW ACCESS is set to direct.
The GP unit's screen editor software allows you to set a window number from 1
to 2000. If you wish to use a number that is 257 or higher, be sure to use the GP
unit's screen editor software to enter this value.
LOCATION
Enter the value used for the (Global WINDOW) LOCATION. This field is enabled
only when GLOBAL WINDOW ACCESS is set to direct.
