4.3.3 EtherCAT®
The EtherCAT bus system only allows one single master. Since the master functionality is typically
assigned to the control system, it is not possible that another controller accesses field devices
independently of the control system.
The Lenze controllers 3231 C/3241 C and p300/p500 are equipped with an "on board" EtherCAT
interface.
[4-1] Sample configuration: Controller 3200 C with EtherCAT

Tip!
Lenze offers complete solutions for EtherCAT as part of the "Logic & Motion" control
technology.
Furthermore, »VisiWinNET®« can be used together with other EtherCAT control systems via
Ethernet if appropriate OPC servers or »VisiWinNET®« direct drivers are available.

Note!
For Industrial PCs of the EL 1xx, EL x8xx, CS x8xx, and CPC x8xx series in control
technology release 2.5, the EtherCAT bus system is not provided.
