6.8.1 Communication parameters for transmission PDO1 (T-PDO1)
This object describes the communication parameters of the first transmission PDO.
Sub-index 0 contains the highest implementable sub-index number. Sub-index 1 describes the COB-ID. When bit
31 of this entry is set, the PDO is deactivated.
The transmission mode is defined by sub-index 2. A blocking period with a resolution of 100 µs can be
parameterized on sub-index 3.
The fourth sub-index specifies the priority class of the PDO.
