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.

 For more information on the use of EtherCAT®, please see the following sets of

documentation:
