Using Deadband Values

You may want to use deadband values to reduce the number of updates sent back and forth to the Server. Deadband values, set in the iFIX Expression Editor, specify the maximum fluctuation you want for the current connection before iFIX updates it. By entering a deadband value, you create a +/- dead zone around the connection's current value. As long as the value is within this range, iFIX does not update the value. However, once the value exceeds the maximum or minimum deadband, the value is updated.
