4.2.6.3 FORMAT EXTRA PARAMETERS TABLE (TAB_FORMAT
2026H)
This table is made by 1000word (200*5) 5 words for each parameter :
st
1 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 :
Type of parameter:
For example:
0x1231 free parameter proportional to the base: the real value is = internal representation/base
th
(4 word).
nd
2 word : it defines the min. value admitted in the internal representation of the parameter
rd
3 word : it defines the max value admitted in the internal representation of the parameter
th
4 word : it defines the representation base of the parameter
th
5 word : it defines the default value of the parameter
example: (hexadecimal if leaded by '0x...'):
st
1 word = 0x1131
nd
2 word = 0000 free parameter in percent of the base: the real value is = (internal
rd
3 word = 8190 representation divided by the base)*100
th
4 word = 4095
th
5 word = 4095
if the current value is 1000
the variation range is included between 0 and 200%
the default value is 100%
88
0 Direct value
1 Percent of the base (100/base)
2 Proportional to the base (1/base)
3 Direct value unsigned
0 Not managed
1 free (changeable on-line)
2 Reserved (changeable off-line + key P60)
4 TDE (changeable off-line + key P99)
(1000/4095)*100 = 24,4%
