____________________________________________________________________

Handling a group of bits as a single variable in ISaGRAF always

means that you handle an integer analog variable. In this case,

boolean informations are linked to an integer analog input or output

ISaGRAF variable, with adapted I/O driver. Mask operations

(and_mask, or_mask, not_mask and xor_mask functions) can be used in

the program to process single bits in the analog value. It is also

possible to create easy C functions blocks to convert an analog

value into many boolean values (and the opposite if needed).
