V1.0

The function decomposes an integer value to 8 bits (which are formed in an array).

Input Type Description
ENABLEDBOOL Enable of function.
IN USINTInput value.
OutputType Description
OUT ARRAY [0 .. 7] OF BOOLOutput array of values

The block decomposes the input integer value IN to individual bits OUT[0..7].

Note: The output array elements are numbered from 0, while the optional binary outputs out1, out2, out3 etc. start with index 1. Thus, e.g. out3 binary output is the value of the out[2] array element.


The block is used to extract bits from an integer value, i.e. status and alarm bits communicated from a 3rd party device.
