Problem
Solution
Point value is FAIL instead
of a value.
• Check that communications are still functioning to the Field
Device.
• Check that the Field Device has been sized with
some number of Analog points.
• Check that the point address is correct in the file and in the Field
Device.
• Check that the data point is correctly mapped to the Master
Station in the file.
• Check that Field Device has a valid value for
that point.
Point value has a
different value than
• Check that the point address in the configuration file
and the Field Device match.
expected.
• Check that the data point is correctly mapped to the
Master Station in the ePAQ file.
• Check that the data point is properly scaled (if scaling is
configurable). Refer to the appropriate ConfigWiz protocol
addendum for more information.
• Check that the data point is properly scaled in the Field Device.
• Allow a sufficient amount of time for the ePAQ to poll and receive an updated
value for the point.
At this point in the Analog data validation process, all options concerning software
parameter adjustments have been attempted. Check that all wiring terminations
and cabling are correct. If those are correct, contact QEI for technical assistance.

Status Data
Status Data displayed by the Maintenance port is reported in 16bit words
(panels) where the least significant bit (LSB) is the rightmost bit of the 16bit
word. Refer to the Diagnostic Command Set in this section for more
information and see Table 5 below.

In the case of Sequence of Events (SOE) data, using the Test Panel will not
suffice for testing. The data validation can be performed, but there is no
mechanism to check time reporting. You must use either a protocol test set or the
actual Master Station to verify SOE data.
