EtherCAT

What is EtherCAT?

EtherCAT (Ethernet for Control Automation Technology) is an open, Ethernet-based fieldbus standard originally developed by Beckhoff Automation, which is being further developed in the EtherCAT Technology Group (ETG). EtherCAT enables communication between devices from different manufacturers without special interface adaptations and is used mainly in automation technology.

Products

EtherCAT AS-i

EtherCAT AS-i 3.0 Gateways in stainless steel provide an interface for an EtherCAT fieldbus. These AS-i gateways are available in various versions with IP20 protection rating.

Number of AS-i networks, number of AS-i Master

"yes, max. 4 A/AS-i network":
Cost-effective power for 2 AS-i networks with 1 power supply (optionally supply of multiple Single Gateways by 1 power supply).

"no, max. 8 A/AS-i network, redundant supply":
1 AS-i power supply per AS-i network. Gateway is powered in normal operation from one of the two AS-i power supplies.

Should one AS-i power supply fail, switching to the other AS-i power supply allows all the diagnostics functions to be maintained and the unaffected AS-i network continues to operate.

"no, max. 8 A/AS-i network":

1 AS-i power supply per AS-i network.

1 power supply, 1 gateway for 2 AS-i networks, inexpensive power supplies

"USB":

"Ethernet diagnostic + Modbus TCP diagnostic":

Access to AS-i Master and Safety Monitor with Bihl+Wiedemann software or via Modbus TCP by using the Ethernet diagnostic interface.

For a full-fledged Modbus TCP fieldbus interface use one of our Modbus TCP gateways in stainless steel or Modbus TCP gateways with integrated safety monitor.

"Ethernet fieldbus + RS 232":

Access to AS-i Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet fieldbus interface or by using an adapter cable via RS 232 interface.


"RS 232":

Access to AS-i Master and Safety Monitor with Bihl+Wiedemann software by using an adapter cable via RS 232 interface.


The latest version of the device description file of the gateway/gateway with integrated safety monitor (GSD, GSDML, EDS, etc.) is available in the "Downloads" section of the respective device.

Diagnostic and configuration interface

Detects whether the same address has been assigned to two AS-i slaves. Frequent error when using a handheld addressing device.

Recognition of duplicate AS-i addresses

Checks the AS-i line for interference effects such as noise, external voltages, ...

AS-i fault detector

Using a C-program offers the possibility to run mini-PLC functions with a gateway.
