EtherCAT Function Blocks That Work With SDOs

ECATReadSDO and ECATWriteSDO are used to work with drive or remote I/O parameters that are not supported by ML and MC function blocks. Drive or remote I/O parameters that have an associated SDO number can be read and written using these function blocks.


  • It takes more than one cycle to execute these function blocks (but less than 100 ms).
