5 Function block protocol
5.1 Data structure
Due to the variety of information to be processed in KS800, logically related data and actions are grouped in
function blocks. A function block has input, output data, parameters and configuration data. For KS800, 25
function blocks are defined. They are all addressed via fixed block addresses (FB no.). Each block is also
divided into several functions. Functions are addressed via function numbers (Fct-no.). Function number 0
addresses function block-specific data.
