Retention
The function block does not recognize retentive data.
Example for BIN operating mode
For simulation purposes in easySoft 7, function block input I1 can be connected to a
marker double word instead of to a binary source. The value of this marker double word
can be entered in hexadecimal or decimal format. It will always be interpreted as binary
at function block input I1.

The most significant nibble determines the sign.
For negative numbers, the two's complement
will be calculated.
Since each decimal value is represented with four bytes or
eight nibbles and each nibble in the BCD code can assume a
value of 9, the largest number that can be represented is
9999999. The smallest number that can be represented is -
9,999,999.
