User mode WITH an Array Definition File
The stand-alone Array Editor User mode dialog when an array definition file is being used is shown below.
To use the Array Editor with an array definition file, proceed as follows:
1. Press the → Browse button. This will display the normal Windows "Open File" dialog and allow the user to
select an array definition file. Array definition files will have the file extension ".zba". The contents of the
file will then be displayed in the dialog. At this point, the "Controller" column will still be empty (since no
arrays have been read from a controller) but all other columns may or may not contain values.
2. Press the → Select button and choose a controller in the same way as before. All arrays will then be read
from the controller and the values will be "merged" into the list along with the existing values from the
array definition file.
3. At any time once a controller is open, pressing → Read from Controller button will re-read all the arrays
from the controller and display the current values in the dialog. The "Read from Controller" string will be
updated to show the date and time when the arrays were read from the controller.
When the Array Editor dialog is closed and any changes have been made, then the user will be prompted
whether or not to save the changes in a file. Saving the changes will allow the changed values to be
retrieved and reviewed at a later time (by using the "Browse" button).
Please note the following points when using the Array Editor with an array definition file:
– Any array element (or any entire array) that does not have a definition within the array definition file, is
not displayed and may not be accessed, even if it exists on the controller. The array definition file will
allow access only to those array elements defined within the file.
– Any array element that is defined within the array definition file but that does not exist within the
controller, is displayed in the list but it is disabled and will be displayed in green. It cannot be selected or
changed.
– Array elements may be flagged as "read-only" in the array definition file. In this case, the check box in
the "R/W" (i.e. Read/Write) column will be clear and the array element will be displayed in green. Read-
only array elements cannot be changed.
– Group headings will be displayed if they have been defined within the file. These are displayed with a
gray background in the "Name" column. These rows in the list cannot be selected. The array element
definitions within a group may correspond to different arrays; all definitions in a group need not come
from the same array.
