33 FSAFE_ TYPE Defines the reaction of device, if a fault is detected.
The calculated ACTUAL MODE remains in AUTO.
0: value FSAFE_VALUE is used as OUT
Status - UNCERTAIN_Substitute Value,
1: use last stored valid OUT value
Status - UNCERTAIN_LastUsableValue
if there is no valid value available, then
UNCERTAINInital_Value, OUT value is = Initial
value
2: OUT has the wrong calculated value and status
Status - BAD_* (* as calculated)
34 FSAFE_VALUE Default value for the OUT parameter, if a sensor or
sensor electronic fault is detected. The unit of this
parameter is the same as the OUT parameter.
35 ALARM_HYS Within the scope of the PROFIBUS-PA specification
for transmitters there are functions for the
monitoring of limit violation (off-limit conditions) of
adjustable limits. Maybe the value of one process
variable is just the same as the value of a limit and
the variable fluctuates around the limit it will occur a
lot of limit violations. That triggers a lot of
messages; so it must be possible to trigger
messages only after crossing an adjustable
hysteresis. The sensitivity of triggering of the alarm
messages is adjustable. The value of the hysteresis
is fixed in ALARM_HYS and is the same for the
parameters HI_HI_LIM, HI_LIM, LO_LIM and
LO_LO_LIM. The hysteresis is expressed as value
below high limit and above low limit in the
engineering unit of xx_LIM.

50 SIMULATE For commissioning and test purposes the input
value from the Transducer Block in the Analog Input
Function Block AI-FB can be modified. That means
that the Transducer and AI-FB will be disconnected.
