Process data preselection (predefined PDOs)

An EtherCAT device usually offers several different process data objects (PDO) for input and output data,
which can be configured in the System Manager, i.e. they can be activated or deactivated for cyclic
transmission.
From TwinCAT 2.11, for suitable EtherCAT devices (as per ESI/XML description) the process data for input
and output can be activated simultaneously through suitable predefined sets via "Predefined PDO
assignment".
The EL33xx devices have the following "Predefined PDO" sets in the "Process data" tab (EL3318 shown in
the example):
Fig. 169: TwinCAT System Manager with predefined PDO option "Standard"
In the "Standard" option [A] (or "inputs only", EL3311, EL3312, EL3314), the input PDOs 0x1A0n are
activated for the corresponding input channels. The output PDOs 0x160n of Sync Manager 2 [B] are
disabled.
