Dynamic objects interact with the PLC controller and must be assigned

PLC addresses. Keep a separate list of dynamic objects for each screen.

Static objects do not interact with the PLC controller, and don’t need a

PLC address. Text, Lines, Boxes, etc., are static and so are not listed in
the Object Address List.

The Alarm window, Information window, and PLC controlled options are
not screen specific. If you use them, list them on a separate Object Address
List.

The I/O Usage Worksheets

There are two I/O Usage Worksheets, one for discrete and one for block
transfer addresses. Use the two I/O Usage Worksheets in conjunction with
the Object Address List to keep track of free and allocated PLC I/O
addresses.

The Object Address List is for all dynamic objects, and for window and
PLC controlled options. Only a few objects require that you fill in all the
columns.
