Process Data Communication
Process Data Communication (PDO Communication) commands and receives Process Data Objects (PDO) with
Master periodically. Data that will be delivered and received is already defined at the initial stage of
communication by PDO Mapping.
PDO communication is categorized as transmission PDO (following Tx PDO) delivers controller status information
and Receipt PDO (following Rx PDO) delivers command from master.
This communication can be used under Operational status of controller and Tx PDO is only available for Safe-
Operational.
