The block divides the Flags input value into individual bits. These bits are then represented on the output.

The block reads the section’s flag value containing info about all flags of the section. The read value is transformed into an individual bit according to a bitmask. Each bit is written onto the corresponding output. According to its position, the bit may have multiple meanings, as listed in the table below.

A Section_Flag read from a control module is connected to the Flags input. All outputs must be connected. Output values have multiple uses, ie. in a web interface for state indication or can serve as a trigger for sending notification or activation of the facility’s security protocols.
