Process data

5.6.1

Process image

The default process image of the EL3681 has 3 inputs (Status, Settings and Value) and one output (Control).
Status/Settings carry special information in the individual bits. From TwinCAT 2.11 these bits are explicitly
accessible in the System Manager (see Fig. Default process image EL3681), although the complete status
word (or Settings and Control) can be linked with corresponding PLC variables.

The size of the transferred process image can be reduced via the PDO option, see Fig. PDO option,
TwinCAT System Manager.
