Serial no. positioner
DEVICE_SER_NUM
Serial number of the positioner.
Uniquely identifies the field device in combination with the manufacturer’s name and
the device type number.
Serial no. valve
VALVE_SER_NUM
Serial number of the positioner’s corresponding valve.
Length: 16 characters
Set point deviation e
SETP_DEVIATION
System deviation in %
Simulation
SIMULATE
Option to indicate a value for the current READBACK position, including status, for
simulation.
State binary input
BINARY_INPUT (M)
States:
Default:
Switching state of binary switch.
0 = not active
1 = active
254 = not evaluated
0
Tag identification
TAG_DESC
Tag identification number of the device.
Length: 32 characters
Text fields
TEXT_INPUT_1... (M)
TEXT_INPUT_3
Available space for entering text.
Length: 32 characters
Tolerance band
TOLERANCE_BAND (M)
Range:
Default:
Reset criterion for monitoring the active control loop. Input of the system deviation
permissible for the monitoring of the active control loop. See also DELAY_TIME.
0.1 to 10.0 %
5 %
Tolerated overshoot
TOL_OVERSHOOT (M)
Default:
If the set point deviation e exceeds the overshoot, the pulse adaptation reduces the
minimum pulses in the moving direction that has caused the overshoot.
If the set point deviation e exceeds the dead band Xtot, but remains within the
overshoot range, the pulse adaptation only reduces the minimum pulses in both
moving directions after two complete amplitudes within the overshoot range.
Adjustment range 0.01 to 10.00 % of the rated travel/nominal angle.
0.5 %
Transducer state
TRANSDUCER_STATE
(M
)
States:
Currently valid state of the transducer block.
0 = See valid operating mode
1 = Forced venting active
2 = Lower travel limit active
3 = Upper travel limit active
4 = End position active at <
5 = End position active at >
Transit time
minimum OPEN
ACT_STROKE_TIME_INC
The min. transit time OPEN (in direction of the 100 % position) is the actual time in seconds
required by the system comprising positioner, actuator and valve to pass through the rated
travel/nominal angle in direction of the valve to be opened (measured during start-up).
