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, backup sensor is in use
A sensor error (broken/shorted) is
detected on the backup sensor, no
backup available
Configuration is temporary invalid < 3
seconds, e.g. while downloading
parameters
Configuration is temporary invalid > 3
seconds, e.g. if download is paused
The device is operated outside its
specified temperature range
The device is operated outside its
specified temperature range in SIL
mode
Power is applied but still too low
The device is transitioning to SIL
mode, or have failed to do so
An unrecoverable error occurred in the
internal communication to the Input
CPU

Check operating temperature
Check operating temperature
Check power supply

If the error is persistant send in the
device for repair
The SIL configuration must be
validated or normal operation must be
re-selected
Reset or re-power the device.
