Process data configuration

The PDOs that can be used for this output channel (A) are described in TwinCAT in the PDO list (B):

Fig.156: Tab "Process data"

The desired PDOs can be enabled in (C), exclusions are displayed.

Each channel can be set to one of the above-mentioned process data formats, e.g. 0x1622 must be enabled for Real32 transmission on channel 1 and the control PDO 0x1621 can be added.

Alternatively, the suggested data sets can be selected from the Predefined PDO list:

This list summarizes frequently used PDO compositions for convenient choice. It should be noted that these then affect all channels at the same time.

• Standard (INT16) -> see above
• Standard (REAL32) -> see above.
• Compact (INT16) -> see above
• Compact (REAL32) -> see above.

During the PDO changeover, other functional units in the data flow may be reset to the default setting!
Therefore, the PDO decision must be made at the beginning; a change requires an ActivateConfiguration.
