Supplement manual Foundation Fieldbus

Local operating with control unit BE2
The handling and all functions are identical to the standard design of the UMC3. However,
not all parameters are mapped to Foundation Fieldbus.
MEASURED
VALUES
Display of the measured values of the transducer block. Please regard: the measured
values will be displayed independent of the settings of the associated AI block.
If the field bus starts a simulation there will be no information about in the display
.
PASSWORD
COUNTER
Totalizer unit and totalizer reset are mapped to the field bus. But some selectable
totalizer units of transmitter UMC3 are not available at Foundation Field bus. If such a
unit is selected, an error message will be displayed.
MEASUREMENT-
PROCESSING
The damping value can only be increased by the field bus. The damping value set by
the local panel is still active even if
PV_FTIME
is set to zero.
Low flow cutoff set by the local panel only affects the local display of the mass flow
and the totalizer but not the output on the Foundation Fieldbus.
The zero calibration can be started by the panel or by the bus.
FLOW
QM unit: the unit of the mass flow in the transducer block will be set.
Attention: XD_SCALE unit in the AI must be set equal via Fieldbus settings!
Some selectable units of transmitter UMC3 are not available at Foundation Field bus. If
such a unit is selected, an error message will be displayed.
DENSITY
Measurement settings on/off/fix and empty pipe limit are mapped to the field bus
.
-Density unit: the unit of the density in the transducer block is set
Attention: XD_SCALE unit in the AI must be set equal via Fieldbus settings!
Some selectable units of transmitter UMC3 are not available at Foundation Field bus. If
such a unit is selected, an error message will be displayed.
TEMPERATURE
Temperature unit: the unit of the temperature in transducer block is set.
Attention: XD_SCALE unit in the AI must be set equal via Fieldbus settings!
PULSE OUTPUT
Not available
STATUS
Not available
CURRENT OUTPUT
Not available
SIMULATION
If the simulation is switched on with the setting “preset of Q, D, T” the measured values
of the transducer block and AI will follow. The respective status is set to “GOOD”
independent from real existing error messages. The parameter “status“ in the transducer
block will show the message “Simulation initiated by local panel”
SELF-TEST
Parameters are not mapped to field bus. Detected errors are indicated by diagnostic
bits.
