A list with an overview of the function blocks and a brief description of
function block coils and contacts is provided at ￫ Section "11.4 List of
function blocks" on page 458.
The term "Marker" generally refers to the standard marker bit (M), also
called auxiliary relay. MFD devices also process marker bytes (MB), marker
words (MW) and marker double words (MD). Markers are used in the
appropriate format for the intermediate storage of data. The marker bits (M)
are used accordingly to store Boolean states 0 or 1.
You can use marker bits (M), marker bytes (MB), marker words (MW) and
marker double words (MD) in the circuit diagram and function block diagram
as well as in the visualization.
