Process data configuration

The process data formats described above can be selected from the Predefined PDO list:

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

Standard (INT16) -> see above

Standard (REAL32) -> see above

Compact (INT16) -> see above

Compact (REAL32) -> see above

Alternatively, the PDOs can be activated individually; the inputs and outputs PDOs (A) that can be used for this input channel are described in TwinCAT in the PDO list (B):

The desired PDOs can be activated in (C) and exclusions are displayed.

Each channel can be set to one of the above-mentioned process data formats. If a Real32 transmission on channel 1 is required, 0x1A02 must be activated. The status is fixed and cannot be deselected.

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 or ReloadDevicesin TwinCAT.
