Bits 0-11 of the higher address of each configuration register indicate the symbols that are
displayed along with the corresponding display value.
These two bits define if the value displayed is taken from a display_value register at address
64 to 79 (see Table 11 on Page 25) or from a sensor_value register at address 48 to 56 (see
Table 10 on Page 24). The following states are valid:
0 – defines that the value is taken from a display_value register that has to be set via
modbus
1 – defines that the value is taken from a sensor_value (+ offset_value) register that is
automatically updated with the current sensor value
VEU:
visible for end user
VSA:
Visible for system administrator
These two bits define if the display value is visible for the end user and/or the system
administrator. If set to ‘1’ the value will be visible.
 See Table 31 on Page 43 for example configurations of display values or set points.
* Please note that config_display_value_3 register is only configured as above per default
for LSTAT-802-Gx-Lx devices for displaying the actual CO
2
level. Otherwise all bits of
this register are set to ‘0’.
semantic_meaning:
is used to provide information about the semantic meaning and the
source of the value. For further information please see Table 30 on
Page 42.
CAL:
if set to ‘1’ the corresponding offset_value can be edited in
CALIBRATION-mode (only capable if DSEU or DSSA is set to
‘1’)
unit_lstat:
defines a unit with which the corresponding display value appears
on the LCD
unit_modbus:
defines a unit that the corresponding display value register appeare
on Modbus
DSEU:
display source for end user
DSSA:
diplay source for system administrator
