Responding to a Displayed Message
Attention Codes
An active message (see Home Page for listing) will
cause the display to toggle between the normal set-
tings and the active message in the upper display
and Attention [Attn] in the lower display.
Your response will depend on the message and the
controller settings. Some messages, such as Ramp-
ing and Tuning, indicate that a process is underway.
If the message was generated by a latched alarm or
limit condition, the message can be cleared when the
condition no longer exists by simply pushing the In-
finity ˆ key or alternatively by following the steps
below. If an alarm has silencing enabled, it can also
be silenced.
Push the Advance Key
to display Ignore [ignr]
in the upper display and the message source (such
as Limit High [Li;h1] in the lower display. Use the
Up ¿ and Down ¯ keys to scroll through possible
responses, such as Clear [`CLr] or Silence [`SiL]
Then push the Advance
or Infinity ˆ key to exe-
cute the action. See the Home Page for further infor-
mation on the Attention Codes.
