J.7.1 Status handling
Normally, the status of the PV reflects the status of the measurement value, the operating
condition of the I/O card, and any active alarm condition. In Auto mode, OUT reflects the
value and status quality of the PV. In Man mode, the OUT status constant limit is set to
indicate that the value is a constant and the OUT status is Good.
The Uncertain - EU range violation status is always set, and the PV status is set high- or low-
limited if the sensor limits for conversion are exceeded.
In the STATUS_OPTS parameter, you can select from the following options to control the
status handling:
BAD if Limited
Uncertain if Limited
Uncertain if in
Manual mode
Note
The instrument must be in Manual or Out of Service mode to set the status option. The AI
block only supports the BAD if Limited option. Unsupported options are not grayed out;
they appear on the screen in the same manner as supported options.
