If an EtherCAT slave is added in the tree view under I/O devices in TwinCAT, the EtherCAT slave is
displayed with all list entries and the corresponding variables. These include variables for the inputs and
outputs and variables, which can be used for diagnostic purposes or which provide additional information
about the EtherCAT slave.
No. Description
1 All input and output variables are arranged under the EtherCAT slave. The
variables can be linked and processed with the PLC program.
2 Process variables can be created under the inputs and outputs of the
EtherCAT slave, which can then be exchanged cyclically.
3 InfoData contains input variables, which provide information about the
EtherCAT slave that only changes rarely.
4 Further settings for the EtherCAT slave can be implemented under the tabs.
When the PLC process image is read, the inputs and outputs of the EtherCAT slave from the tree view can
be linked with the variables of the PLC program. Double-click on a variable name in the tree view to open the
link dialog. The linked signals are indicated by a small arrow on the signal symbol.
