2.1.1.8.4 Function macros

Function macros are instances, which carry out stand-alone or multiple MP-
Bus communications. They are responsible for the sequential flow
(transmit/receive) of MP-Bus telegrams. On completion of the evaluation of
slave responses, function macros decide independently on how to proceed.
Function macros return compact information as a response, and thus relieve
the burden on the module bus and the function blocks.
Appropriate function macros are available for Type 1 and Type 2 MP-Bus
addressing. These macros are used by the function block
"FbMpBusAddressing".
