set_point_index
[0x01]
These registers are used to associate a set point as source for the bar graph on the left and on the right side
of the LCD. If enabled the bar graph is updated corresponding to the value of the set point defined with
the set_point_index.
The bar graph segments can also be set manually by writing the symbol_direct_access registers at address
99 and 100 ( Table 12 on Page 23)
set_point_index
:
defines a set point register that is used as source for the bar graph.
EN
: if set to ‘1’ the corresponding bar-graph will be updated to visualize the value of
a set point with the defined set_point_index.
