EtherCAT and E-bus Modules - Frequently Asked Questions ★★ EtherCAT Bus Usage Requirements

1.What type of cable must be used for EtherCAT? 

In a lab environment, regular Category 5e cable is sufficient. For field use, it is recommended to use double-shielded Category 5e cable.

2.Does the EtherCAT network support a "ring" topology? 

Yes, a ring network can be implemented. Two independent network cards are required. Additionally, software needs to be installed to achieve this functionality.

To achieve this functionality, you'll need to install software.

It's not free.

3. If the distance between EtherCAT slaves is 100m, can the total length be very long? Can it be 1 kilometer?

Yes, 1 kilometer is not a problem. The distance between stations using fiber optics can reach up to 2km.

4. Can EtherCAT form a redundant network? If so, what hardware and software does the master require?

Yes, it can. You need two master ports and the TF6220 software package.
