Introduction
This section describes the individual PDOs and their content. In each case only the first channel is
described. The second channel is analogous. 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).
