EtherNet/IP + Modbus/TCP Fieldbus system

EtherNet/IP + Modbus/TC

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.
