7.5 Process data
Introduction
This section describes the main PDOs and their content. A PDO (Process Data Object) is a unit on cyclically
transmitted process values. Such a unit can be an individual variable (e.g. the supply voltage as a 32-bit
value) or a group/structure of variables. The individual PDOs can be activated or deactivated separately in
the TwinCAT System Manager. The ‘Process data’ tab is used for this (visible only if the terminal is selected
on the left). A change in the composition of the process data in the TwinCAT System Manager becomes
effective only after restarting the EtherCAT system.

7.5.1.1 PDO Assignment
In order to configure the process data, select the desired Sync Manager (SM 2 + 3 can be edited) in the
upper left-hand "Sync Manager" box. The process data assigned to this Sync Manager can then be switched
on or off in the "PDO Assignment" box underneath. Restarting the EtherCAT system, or reloading the
configuration in configuration mode (F4), causes the EtherCAT communication to restart, and the process
data is transferred from the terminal.
The following PDO assignments are possible:
