The Extended Status screen for the DFA instruction gives you information
about your inputs at the bit level. The information is less complex than
that of the Extended Status screen for the SDS instructions because DFA is
a monitoring only function.
While in the Extended Status screen, you can use
[F2] - Display Comment/Symbol/Adr to select between address
comment, symbolic name, or logical address of I/O. The function key
always displays the next format; for example, if address comments are
being displayed, then
[F2] reads “Display Symbol.”
Certain problems could occur while you are configuring your operator
interface. The following table lists some problems that could occur.

address specified is the correct address.
System is displaying messages from the
SDS but they are printing with the database
tag instead of the address comments you
entered in the SDS instruction Import or update the message database
(refer to chapter 6).
