The output status is based on the actual mode of the block and on the status of the IN_1 block input. When the IN_1 status is Bad, the block sheds to Man mode and the status of OUT becomes GoodCascade Const. In addition, you can choose the block to shed its target mode to Man mode when IN1 status is Bad by selecting the following status option (STATUS_OPTS):
Target to manual if bad IN
The status of IN is reflected in the PV value but has no effect on control operation.
You can set the status option in Manual or Out of Service mode only.
