FY303 – Operation, Maintenance and Instructions Manual
3.4
Parameter
Transducer Block Description
TAB_X_Y_VALUE
The X_Y_VALUE parameter contains one value couple of the table
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_MAX_NUMBER
TAB_MAX_NUMBER is the maximum size (number of X_VALUE and Y_VALUE values) of the table in the
device.
TAB_ACTUAL_NUMBER
Contains the actual numbers of entries in the table. It shall be calculated after the transmission of the table is
finished.
SELF_CALIB_STATUS
Result or status of the device-specific (manufacturer specific) calibration-procedure.
0 = undetermined (mandatory)
2 = aborted (optional)
4 = error in mechanical system (optional)
11 = timeout (optional)
20 = aborted by means of “Emergency override active“ CB_OVERRIDE (optional)
30 = zero point error (optional)
254 = erfolgreich (optional)
255 = no valid data (optional)
Smar:
0 = Self Calibration OK.
3 = No magnet part detected.
4 = Error in mechanical system.
11 = Timeout.
12 = Pressure problem.
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 initialized
1:
new operation characteristic, first value (TAB_INDEX=1), old curve cleared
2:
reserved
3:
last value, end of transmission, check table, swap the old curve with the new curve, and actualize
ACTUAL_NUMBER.
4:
delete point of table with actual index (optional), sort records with increasing Charact-Input-Value,
assign new indexes, and 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 and 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 initialized
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
> 128 manufacturer specific
TOTAL_VALVE_TRAVEL
Accumulated valve travel in nominal duty cycles.
TOT_VALVE_TRAV_LIM
Limit for the TOTAL_VALVE_TRAVEL in nominal duty cycles.
TRAVEL_LIMIT_LOW
Lower limit of the valve position in percent of travel span. Travel span correspondents to OUT_SCALE.
TRAVEL_LIMIT_UP
Upper limit of the valve position in percent of travel span. Travel span correspondents to OUT_SCALE.
TRAVEL_RATE_DEC
Configurable seconds to full span change (closing time of the valve) in seconds.
TRAVEL_RATE_INC
Configurable seconds to full span change (opening time of the valve) in seconds.
VALVE_MAINT_DATE
Date of last valve maintenance.
VALVE_MAN
Name of Valve Manufacturer.
VALVE_SER_NUM
Serial-number of the valve belonging to the positioner or the electronic device.
VALVE_TYPE
Type of valve:
0
= linear moving valve, sliding valve
1
= rotary moving valve, part-turn
2
= rotary moving valve, multi-turn
