Incident Description
The device variable mapped to PV (and
analog out put current) is beyond its
operating limits.
Any other device variable is beyond its
operating limits.
The loop current has reached the
Current Output Upper Limit (UL) or
Output Lower Limit (LL) as configured
with command #147, and is no longer
corresponding to the PV value.
The analogue output current is being
simulated or disabled.
The configuration has changed since
this bit was last cleared (seen from
same master type, Primary- or
Secondary Master).
A sensor error (broken/shorted sensor)
is detected on Input 1
A sensor error (broken/shorted sensor)
is detected on Input 2.
This is only possible if Input type 2 is
<> "None"
A sensor error (broken/shorted sensor)
is detected on the CJC measurement
used for Input 1
A sensor error (broken/shorted sensor)
is detected on the CJC measurement
used for Input 2
The difference between measurements
on Input 1 and Input 2 is outside the
configured sensor drift limit
A sensor error (broken/shorted) is
detected on the primary sensor,
backup sensor is in use
A sensor error (broken/shorted) is
detected on the backup sensor,
primary sensor only is available
Configuration is temporarily invalid
< 3 seconds, e.g. while downloading
parameters
