PDOs will not be acknowledged and are suitable for time critical applications.
By using the full 8 bytes for data, there is no additional information about transmitted
objects. Therefore the PDO producer and the PDO consumer have to define the PDO-
mapping.
PDOS can be sent on different ways:
• On request: A node sends a RTR frame to ID of the designated PDO and the
encoder returns the PDO. (The CiA strongly recommends not to use RTR
frames. Therefore RTR is not supported by Wachendorff Automation
encoders!)
• Synchronously: On the reception of a SYNC message the node send its
PDOs.
• Asynchronously: The sending of the PDOs is triggered by an internal event
(e.g. the internal event timer).
5.3.3 Object dictionary
The object dictionary lists all data types, objects and functions of the communication
and the device profile. There are also manufacturer specific objects listed. The objects
are addressed by 16-bit indices (lines) and 8-bit sub-indices (columns).
Table 5.3 shows the structure of the object dictionary:
