6-6 AT_IO_Modules_Adv_Lib
The AT_IO_Modules_Adv_Lib provides all the functions to manage the sigma due
series I/O modules. To explicit use of the protocol messages (SDO, PDO, EMCY,
SYNC, …) please use configuration files such as EDS and DCF (see the “
I/O Function
Block Library
” [ 12 ] manual for details). The table here reported gives the complete list of
the function blocks of the library.
