The plain text display of the bit meanings is particularly helpful not only in commissioning but also for linking
to the PLC program.

(B).
Activation of the "Show Sub Variables" button (C) displays all subvariables and links to the PLC (D) in the
online view.

The process data to be transmitted (PDO, ProcessDataObjects) can be selected by the user
• for all TwinCAT versions via the "Predefined PDO Assignment" selection dialog (see fig. "EL2819
