The 2800 keypad is made up of twenty tactile feedback keys used for navigation, control, and data entry.
Select Key
This key is used to select a variable field you want to modify or initiate action from. Within this document we refer
to this as “assigning focus”. Each time the
Select
key is pressed, a flashing block character will be displayed.
Depending on the field type, the character will be over the left most character (Drive Data) or over the entire field
(Data Set, Bit Status, Multi-State Text). As the
Select
key is pressed, focus will move from variable field to
variable field in the order that they were created. When the
Select
key is pressed and no additional variable fields
exist, the flashing cursor will move off screen.
If the
Select
key is pressed but no variable fields are
accessible the following message will momentarily display.
Enter Key
This key is used to initiate the writing of a value to the Drive.
!
After modifying the value in a Drive Data field, the
Enter
key is pressed to initiate the writing of the new
value to the Drive. If writing is successful, focus will be removed from this field and the cursor will move
off screen.
!
If a Data Set field has been selected, pressing the
Enter
key will write the assigned value to the Drive. If
writing is successful, focus will be removed from this field and the cursor will move off screen. If more
than one variable is specified the message “WRITING RECIPE DATA” will appear on the display until
the process is complete. If this field is configured as a Increment or Decrement type then after pressing
the
Enter
key the 2800 will first read the current value from the Drive, add or subtract the assigned value
then write the new value back to the Drive. The focus will remain on this field until the
Select
key
transfers it or the
Cancel
key is pressed..
!
If a Bit status field has been selected, pressing the
Enter
key will toggle the state of the target bits in the
Drive which will also change the character string displayed. Focus will then be removed from the field
and the cursor will move off screen.
!
If a Multi-State Text field has been selected, pressing the
Enter
key will write the value associated with
the text currently displayed to the Drive. The
Next
and
Prev
keys are used to scroll between choices
offered by the Multi-State Text field.
Cancel Key
This key is used exit or back out of an operation.
!
If the
Select
key is being used to assign focus to a field, pressed the
Cancel
key will remove focus and
move the cursor off screen.
!
If you are currently keying data into a field, pressing the
Cancel
key once will clear the entered field data
leaving only a cursor. You may begin entering a new value. Pressing the
Cancel
key twice in a row will
remove focus from the field.
