4.2.6.3 FORMAT EXTRA PARAMETERS TABLE (TAB_FORMAT
2026H)
This table is made by 1000word (200*5) 5 words for each parameter :
1
st
word : it defines the parameter typology, its internal representation and the number of decimal and
integer digits which are shown up on the display. Each nibble has the following meaning:
0x 0 0 0 0 (in hexadecimal)
number of digits visualised in decimal
number of digits visualised in integer
internal representation :
0 Direct value
1 Percent of the base (100/base)
2 Proportional to the base (1/base)
3 Direct value unsigned
Type of parameter:
0 Not managed
1 free (changeable on-line)
2 Reserved (changeable off-line + key P60)
4 TDE (changeable off-line + key P99)
For example:
0x1231 Æ free parameter proportional to the base: the real value is = internal representation/base
(4
th
word).
2
nd
word : it defines the min. value admitted in the internal representation of the parameter
3
rd
word : it defines the max value admitted in the internal representation of the parameter
4
th
word : it defines the representation base of the parameter
5
th
word : it defines the default value of the parameter
example: (hexadecimal if leaded by ‘0x…’):
1
st
word = 0x1131
2
nd
word = 0000 free parameter in percent of the base: the real value is = (internal
3
rd
word = 8190 representation divided by the base)*100
4
th
word = 4095
5
th
word = 4095
if the current value is 1000Æ (1000/4095)*100 = 24,4%
the variation range is included between 0 and 200%
the default value is 100%
