Condensed Status (GOOD)
Status - GOOD
Description
GOOD – initiate fail
This fault is not generated by the product, but can be simu-
safe
lated.
GOOD – maintenance
Value is valid. Maintenance is recommended within a medi-
required
um-term period.
GOOD – maintenance
Value is valid. Maintenance is demanded within a short- term
demanded
period.
GOOD – function
Device performs internal function check without influencing
check
the process. Value is valid.
Condensed Status (UNCERTAIN)
Status - UNCERTAIN
Description
UNCERTAIN – substi-
Output of Failsafe logic only.
tute set
UNCERTAIN – initial
Default value as long as no measured value is available or
value
until a diagnosis is made that affects the value and the status
accorded to it.
UNCERTAIN –
Usability of the process value depends on the application.
maintenance
Value is potentially invalid. Cause can be determined by
demanded
reading the extended diagnostics
manded within a short-term period.
UNCERTAIN – simu-
Indicates the start of a simulation.
lated value, start
Simulation of a measured value or Input FB mode changes
from AUTO to MAN.
•
•
•
UNCERTAIN – simu-
Indicates the end of a simulation.
lated
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.
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.
