9.11 CRT Context Keys
Each user can set up a personalized working environment or context, which can include multiple Operator
Windows and their contents, as well as the size and position of Quick Key keypads associated with the
Operator Windows. Different users have different contexts, depending on their area and responsibilities,
and each user may have a number of different contexts which are used repeatedly. Using CRT Context
Keys saves time and effort by bypassing the numerous keystrokes necessary to open multiple Operator
Windows and call up the appropriate displays.
9.11.1 Preparing the Context
The size, location and contents of each Operator Window on a screen can be stored and assigned to a
CRT Context Key. In order to assign this information, the user must first set up the working environment on
a Micro-PWC. For example, a user might have two windows open on a screen: one in which a Sequence is
being controlled and one containing an associated graphic. By assigning this set of displays to a CRT
Context Key, the user can return to this screen environment with ease by selecting the appropriate CRT
Context Key.
9.11.2 Initial Display Layout Login
The Login Context Key is assigned to the user’s initial display layout, which appears automatically each
time the user logs in. If a user has no context assigned to the Login Context Key, the previous contents of
the screen remain after the user logs in. In the case of the Default User state (no user logged in), the initial
display layout consists of one Operator Window containing the System Status Display. The user can
change the contents of this window and/or increase the number of windows in the Default User initial lay-
out. Clearing this layout will always cause it to return to the single Operator Window/System Status Display
combination.
9.11.3 Accessing CRT Context Keys
CRT Context Keys allow each user to save up to 17 working contexts (the Login Context Key plus 16 addi-
tional keys) and assign each context to one individual key which appears on the screen. To access the
CRT Context Keys option, from the System Window select Menu > Windows > CRT Context Keys. A win-
dow known as the CRT Context Keys keypad will be displayed. This window contains the set of CRT
Context Keys available in the current user’s login configuration (
Figure 9-15 ).
