Note the following points with regard to the deviation message:
Notes on use and
configuration
• Set the message delay time long enough so that the plant does not trigger a
fault status message on startup
• The deviation message always refers to the sequence controller. Therefore, in
the case of room-supply air temperature cascade control, it monitors the supply
air. Set the values accordingly
• The deviation message only works when the control process is active
• If a sequence is limited by a general or sequence limiter, it will not generate a
deviation message
• The assignment is made in the configuration diagram, always at sequence
controller 1
• If you set both the deviation message and the timeout period for the sequence
controller, ensure that the message delay time for the deviation message is
longer than the timeout period
If you fail to do so, there will be a deviation message every time the timeout acts
on the sequence controller
