Set if the value is not useful because there is some other problem with the block,
depending on what specific manufacturer can detect.
Set if this input is not referenced in by a link object within the resource.
Set if the source of the value is affected by a device failure.
Set if the device can determine this condition. The Limits define which direction has
been exceeded.
Set if this value had been set by communication, which has now failed.
Set if there has never been any communication with this value since it was last Out of
Service.
The value is not reliable because the block is not being evaluated, and may be under
