Variant Predefines PDO

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 ELX331x devices have the following Predefined PDO sets in the Process data tab (EL3314 shown in the
example):

In the Standard option [A], the input PDOs 0x1A0n are activated for the corresponding input channels. The
output PDOs 0x160n of Sync Manager 2 [B] are disabled.
