Section 5:
Key Definitions
-/Next & ./Prev Keys
These keys are dual function.
!
If the Select key has not placed focus on any variable fields then the -/Next and ./Prev keys are used
for navigation. When a screen is created using ScreenMaker 2000K the system engineer has the option
to assign a next and previous screen linking number. Refer to Section 4: Methods of Screen Triggering,
to review this feature.
!
If the Select key has been used to place focus on a Drive Data field then the minus and decimal point
function becomes active. Note however, these keys may be ignored if the field format does not support
negative or decimal numbers. If focus has been placed on a Multi-State Text field then these keys allows
scrolling through the field choices.
Numeric Keys 0 through 9
These keys are used exclusively for entering values into Drive Data fields or entering field lock codes.

Lock Key

This key is used to access the global lock code activation / deactivation screen. The 2800 provides fifteen lock
codes that can be specified during setup. When a Drive variable field is created using ScreenMaker 2000K, the
designer can assign one of the lock codes to the field. When an operator tries to access a locked field a screen will
pop up that prompts them for the lock code. Using the Lock key to deactivate a lock code allows the operator to
access any field that uses that lock code with out re-entering it each time the field is accessed. In other words, it
acts as a global lock override. Security locks are discussed in detail in Section 6.

Function Keys

These four keys are programmable function keys that can be re-defined for each screen created for the 2800.
There are four different configurations that can be made for a key, or a key may be disabled. Within each screen
the four keys may be configured differently. A function key can also be set to operate as a momentary pushbutton
switch or maintained pushbutton switch. The configuration options are as follows:
Pushbutton
This configuration is used exclusively with write only Drive parameters such as.
Define Home Position
Pressing the key will cause the assign function to be executed.
Selector Switch
This configuration is used exclusively with the dual state variables such as: Drive Enable
Pressing the key will toggle the variable between the "1" and "0" state
Screen Trigger
This configuration allows the key to function as a screen trigger. Unlike the Next and Prev
keys, this screen trigger can write to either Screen Trigger Word or both at the same time.
For more information refer to Section 4, screen trigger method three.
