Actuator model
ACT_MODEL
W
S
Actuator design.
Actuator serial number
ACT_SER_NUM
W
S
Serial number of the actuator.
Valve manufacturer
VALVE_MAN
W
S
Name of valve manufacturer.
Valve model
VALVE_ID
W
S
Valve design.
Valve type
VALVE_TYPE
W
S
Describes the type of valve (linear, turning, other, undefined).
Valve serial number
VALVE_SER_NUM
W
S
Serial number of the valve.
PRIMARY_VALUE_D
The valve position which is transferred to the function block.
Valve position
VALVE_POSITION_D
The current valve position (closed, open, intermediate, unknown).
Valve Position Extended
VALVE_POSITION_EXTEN
DED_D
The current valve position with additional information such as "valve
opening" and "valve closing" if the valve is in the intermediate position.
Sensor Value A
SENSOR_VALUE_A_D
The current value of PFC A
(0 = low current, 1 = high current).
Sensor Value B
SENSOR_VALUE_B_D
The current value of PFC B
(0 = low current, 1 = high current).
Sensor Usage
SENSOR_USAGE
W
S
OOS
This parameter describes whether a final position feedback is con-
nected to the valve interface and whether or how its signals shall be
evaluated.
PV_D Generation
PV_D_GENERATION
W
S
OOS
If the signal of the final position feedback are evaluated, this parame-
ter determines how to further process the evaluated PFC signals prior
to transferring them to the function block.
Sensor Lead Fault Monitor-
ing
SENSOR_LEAD_
FAULT_MONITORING
W
S
In this parameter the lead breakage and/or lead short circuit monitor-
ing can be activated for the PFC wiring.
Sensor Lead Fault
SENSOR_LEAD_ FAULT
Lead breakage and lead short circuit of the PFC wiring are displayed
here if monitoring has been activated.
Valve Monitoring
VALVE_MONITORING
W
S
Time measurement for the valve, stroke counter and the cyclic func-
tional tests can be activated in this parameter.
Stroke Counter
STROKE_COUNTER
W
The current value of the stroke counter. This value is always increased
by one as soon as the valve reaches the open position after a modifi-
cation of the reference value. It is possible to specify a start value.
Stroke Counter Limit
STROKE_
COUNTER_LIMIT
W
S
As soon as the stroke counter exceeds this value, a diagnosis mes-
sage is released.
Cyclic Test Period
CYCLIC_TEST_PERIOD
W
S
If the reference value of the valve is not modified for this time, a cyclic
functional test is carried out (if activated).
Auto Init Command
(Initialisation run)
AUTO_INIT_CMD
W
The transducer block can automatically determine the parameter
"Sensor Usage" and the reference values for the valve transit and
breakaway times during an initialisation run. Initialisation is started by
this parameter. This parameter should not be used directly but always
via the Setup Wizard.
Auto Init Status
(Status of initialisation run)
AUTO_INIT_STATUS
The current status of the initialisation run is signalled here.
Parameter
Char.
