15.3 Configuration of EtherCAT devices
In principle, EtherCAT devices can be configured as "EtherCAT Master" or
"EtherCAT Slave". Several EtherCAT Slave devices can be connected to a
EtherCAT Master (e.g. the control functions as master and can be con-
nected with slaves).
15.3.1 Configuring EtherCAT Master
Open the configuration window by double-clicking on the EtherCAT node.
The EtherCAT Master configuration window consists of the following tabs:
● EtherCAT Master
● Status
Tab "EtherCAT Master"
The general master configuration can be carried out here.
Element Meaning
Timing mode
● Cycle time: Insert a cycle time in μs.
● Task: Select a configured task
Activate cross-
communication
Activates cross-communication between drives and encoder box.
Cross-communi-
cation cycletime
Cycletime of the cross-communication between drives and encoder box.
Simulation mode
The bus master can be set to "Simulated" to be able to carry out tests
without physical slaves. All slaves are then automatically set to "Simu-
lated".
The area Info shows information about the manufacturer and the device. The
remaining parameters of an EtherCAT Master can be found in the area "Ad-
vanced" in a tree structure. These parameters do not need to be switched for
normal operation.
Tab "Status"
Various analysis parameters are shown here, which provide information
about the EtherCAT bus of a running control.
