3 Methods for Safety Programming

3.8

Accessing global data

Recommendation



Connect global data (inputs, outputs, data blocks) at the highest block

hierarchy level (Main Safety).



Use the block interfaces to pass signals to lower levels.

Advantages



Modular block concept



Reuse of program parts in other projects without modifications



Reduces programming errors



Makes the overall program easier readable as the general function of a block

can already be estimated from the interfaces.
