EtherNet/IP + Modbus/TCP

What is EtherNet/IP?

EtherNet/IP (Ethernet Industrial Protocol) is an open, CIP-based fieldbus standard developed by Rockwell Automation and the ODVA (Open DeviceNet Vendor Association) which is used mainly in automation technology. EtherNet/IP enables communication between devices made by different manufacturers without any special interface adaptations.

What is Modbus/TCP?

Modbus TCP/IP is an open fieldbus standard for industrial communication using ethernet. It is used mainly in automation technology and enables communication between devices from different manufacturers without any special interface adaptations.

EtherNet/IP + Modbus/TCP AS-i Gateways

EtherNet/IP + Modbus/TCP AS-i Gateways in stainless steel provide an interface for an EtherNet/IP + Modbus/TCP fieldbus. These AS-i gateways are available in various versions with IP20 protection rating.

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.
