4.2.9.2 Approaching the Substitute Value

The substitute value can be approached in two ways:
• "Hard" approach to substitute value: There is no ramp; instead, the parameterized sub-
stitute value is output directly.
• "Soft" approach to substitute value: The stop ramp is used to approach the substitute
value.
When the fault on the local bus is cleared, the value continues to be held until this state
has been acknowledged; see
knowledgement
