Multiplex PDO services

CANopen Add On according to CiA 301

[DeepL] sysWORXX CANopen Source Code

The MPDO add-on module provides multiplex PDO services according to CiA 301. A multiplex PDO is a special PDO which is used where more process data has to be transferred than "normal" PDOs are able to transfer. MPDO's are used for example with CANopen lifts (CiA 417).

To use the Add-On Module the CANopen Master Slave Stack or CANopen Manager Stack is required.

Properties / Details

Within a MPDO message the source address (Source Address Mode) or destination address (Destination Address Mode) of the data is transmitted by its respective index or subindex. Therefore 4 bytes per MPDO message are reserved for the data itself.

The common implementation of the MPDO Addon module supports the Destination Address Mode (DAM) function. Thus it supports a DAM creator and DAM receiver.
