PARAMETERS
DESCRIPTION
TAB_ACTUAL_NUMBER
Contains the actual numbers of entries in the table. It shall be calculated after the
transmission of the table is finished.
TAB_ENTRY
The index parameter identifies which element of the table is in the X_VALUE and
Y_VALUE parameter currently
TAB_MAX_NUMBER
TAB_MAX_NUMBER is the maximum size (number of X_VALUE and Y_VALUE
values) of the table in the device.
TAB_MIN_NUMBER
For device internal reasons (e.g. for calculation), sometimes it is necessary to use a
certain number of table values in minimum. This number is provided in the
TAB_MIN_NUMBER parameter.
TAB_OP_CODE
The modification of a table in a device influences the measurement or actuation
algorithms of the device. Therefore an indication of a starting and an end point is
necessary. The TAP_OP_CODE controls the transaction of the table.
0
: not initialised
1
: new operation characteristic, first value (TAB_INDEX=1), old curve cleared
2
: reserved
3
: last value, end of transmission, check table, swaps the old curve with the new
curve, actualise ACTUAL_NUMBER.
4
: delete point of table with actual index (optional), sort records with increasing
Charact-Input-Value, assign new indexes, decrement CHARACT_NUMBER.
5
: insert point (Charact-Input-Value relevant) (optional), sort records with increasing
Charact-Input-Value, assign new indexes. Increment CHARACT_NUMBER.
6
: replace point of table with actual index (optional).
It is possible to read a table or parts of the table without start an stop an interaction
(TAB_OB_CODE 1 and 3). The start is indicated by set TAB_ENTRY to 1.
TAB_STATUS
It is common to provide a plausibility check in the device. The result of this check is
indicated in the TAB_STATUS parameter.
0
: not initialised
1
: good (new table is valid)
2
: not monotonous increasing (old table is valid)
3
: not monotonous decreasing (old table is valid)
4
: not enough values transmitted (old table is valid)
5
: too many values transmitted (old table is valid)
6
: gradient of edge too high (old table is valid)
7
: Values not excepted (old values are valid)
8
:
127
reserved

manufacturer specific
TAB_X_Y_VALUE
The X_Y_VALUE parameter contains one value couple of the table
LIN_TYPE
Type of linearisation.
0
= no linearisation (mandatory)
1
= linearisation table (optional)
240
= Manufacturer specific
249
= Manufacturer specific
250
= Not used
251
= None
252
= Unknown
253
= Special
FEEDBACK_CAL
This parameter should be set with the actual output current during the calibration
procedure.
CAL_CONTROL
This parameter controls when the calibration procedure ends. It is necessary since the
user should enter the "analog current" value that he sees at the multi-meter. The device
waits for a flag that tells it when to change from trim mode to normal one.
ACTUATOR_ACTION
Fail-Safe position for power-loss of the actuator resp. the valve:
0
= not initialized
1
= opening (100%)
2
= closing (0%)
3
= none / remains in actual position
SP_RATE_INC
Ramp rate at which upward setpoint changes are acted on in Auto mode, in FV units
per second. If the ramp rate is set to zero or minus infinite then the setpoint will be
used immediately.
SP_RATE_DEC
Ramp rate at which downward setpoint changes are acted on in Auto mode, in FV
units per second. If the ramp rate is set to zero or plus infinite then the setpoint will be
used immediately.
SP_HI_LIM
The setpoint high limit is the highest setpoint operator entry that can be used for the
