Cell Name
The strings in the column title describe cell names. They do not have to be unique; cell
names are just for user support.

Bit Count
This crucial information defines the length of the cell and - based on the previous cells
- also the cell end position and the next cell start position within a frame.
If, for a given bit count, the Condition value is longer, it is truncated. If the condition
value is shorter, it is padded with 0. Both truncation and padding occur at the left side
of the condition value.
Examples:
●
if "Condition" is "=111000" and the Bit Order is "MSB", then
– if "Bit Count" is 4, the truncated condition is "=1000"
– if "Bit Count" is 8, the padded condition is "=00111000"
●
if "Condition" is "=111000" and the bit order is "LSB" (accordingly, the condition in
"MSB" format would be "=000111"), then
– if "Bit Count" is 4, the truncated condition is "=1000" for LSB and "=0001" for
MSB
– if "Bit Count" is 8, the padded condition is "=00111000" for LSB and
"=00011100" for MSB
These examples are true for the Numeric Format specified as "binary".

Condition
This text field is used to apply various conditions and functionalities for a cell. Among
others, it can be used to identify mandatory values (such as CRC checksum or ID) that
help to identify a frame. The numeric format and bit order of the condition value has to
match up with what is defined in the fields Numeric Format and Bit Order.
The following conditions are implemented:
