Condensed Status (UNCERTAIN)
Status - UNCERTAIN Description
UNCERTAIN – Indicates the start of a simulation.
simulated value, start
Simulation of a measured value or Input FB mode changes
from AUTO to MAN.
•
•
•
UNCERTAIN – Indicates the end of a simulation.
simulated
Simulation of a measured value is disabled or Input FB mode
value, end
changes from MAN to AUTO.
This Status remains active for 10 seconds after simulation
ends.
While this status is active there is no reliable process value.
Measured values and their status are updated
afterwards.
Condensed Status (BAD)
Status - BAD Description
BAD – non specific Proxy determines that a device does not communicate.
BAD – passivated Configured failsafe value is used, accompanied by this
(diagnostics status.
alerts disabled)
BAD – maintenance No measurement available because of a failure.
alarm, more
diagnosis available
BAD – process No measurement available because of invalid process
related, no conditions.
maintenance
BAD – function check Occurs during cleaning or calibration process.

This status remains active for at least 10 seconds:
– after enabling simulation
– after setting the FB to MAN mode
– after a restart (e.g. power down cycle) if the simulation
is enabled or the FB is in MAN mode
– after passivation is cleared if simulation is
enabled or the FB is in MAN mode
In MAN mode the status remains until a subsequent write
command overwrites the OUT value after the 10 seconds
have expired.
In simulation mode the written status is buffered and
appears in the value flow after 10 seconds. However the
new written SIMULATE parameter with its status can be
read before the 10 seconds have expired.
