Display operation

6.1

Data types, value ranges

The Codix 538 CAN display only displays the
transmitted figures when it is in the "Operational"
status. The display supports a reception PDO,
which allows reading all supported data types also
via PDO.
6.2

Decimal point display

The number of decimal places must be set between
0 and 5. The display rounds the figure to the set
number of decimal places.
The displayed figure is calculated using the
following formula:
Displayed figure = received figure * Factor + Offset

for positive figures and all D segments for negative
figures.

Display element

Each of the 7 segments can be controlled
individually.
6.7 Direct segment control using
Object 5100
Each of the 8 segments of the 6-digit display can
be controlled directly. The status of the 8 segments
(A..F, DP) can be described using a byte (UINT8,
value range 0 to 255) as the sum of the values.
