LCD Screen Editor: Using Editable Fields

Fields can be read only or editable. There are three elements that control the behavior of an editable field:

Editable or Read Only.
You must first specify when a field is editable or not. This is done in the field pane's Format tab using the Editable check box. Some fields such as status fields cannot be editable. For these fields, the Editable check box will be unavailable.
Edit Limits.
For editable integer fields, you must specify the range of values that can be accepted. The edit limits are defined on the field pane's Format tab in the Editable area. When an LCD420 user tries to enter a value outside of the edit limits, the value will not be used, and instead an error message will be displayed instructing the user of the field's limits. For example:

Write Locations.
A write location is a register in the RMC that is changed when a new value is entered for a field. When a field is first made editable, it will automatically have a single write location that matches the Data to Display area in the field pane's Data tab. For most fields this is all that is required. However, editable integer fields can have more than one write location.
