The plain text display of the bit meanings is particularly helpful not only in commissioning but also for linking
to the PLC program.
By right-clicking on the Status variable in the configuration tree (A), the structure can be opened for linking
(B).
Activation of the “Show Sub Variables” button (C) displays all subvariables and links to the PLC (D) in the
online view.
“Predefined PDO Assignment” selection dialog (from TwinCAT 2.11 build 1544 onwards)
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
Process Data tab” A) or
• selectively for individual PDOs (see fig. “EL2819 Process Data tab” B)
These changes become effective after activation and an EtherCAT restart or a reload.
