ABB Implementation

EtherNet/IP for ABB

Industrial Protocol using standard Ethernet and TCP/IP. Primary protocol for Rockwell Automation (Allen-Bradley) systems.

Type: Industrial EthernetSpeed: 10/100/1000 MbpsReleased: 2001Organization: ODVA (Open DeviceNet Vendors Association)

Protocol Overview

ABB AC500 supports EtherNet/IP via add-on libraries in Automation Builder (CODESYS). Limited native support - primarily via third-party gateways or specific modules.

When to Use EtherNet/IP

Choose EtherNet/IP for Rockwell/Allen-Bradley systems, North American facilities, or when standardizing on CIP family protocols.

ABB Hardware Requirements

Compatible Communication Modules

CP600-EIP (AC500 EtherNet/IP scanner)

HMS gateway (EtherNet/IP to PROFINET)

Wiring Details

Network Setup

100Mbps Ethernet via CP module or gateway. Star topology via standard switches.

Configuration

Import EDS files in Automation Builder. Configure scanner/adapter in library configuration. Map I/O to controller variables.

ABB Code Example

VAR
  EIPScanner : EtherNetIP_Scanner;
  DeviceInput : ARRAY[0..9] OF WORD;
  DeviceOutput : ARRAY[0..9] OF WORD;
END_VAR

EIPScanner(
  Enable := TRUE,
  IPAddress := '192.168.1.10',
  InputAssembly := 100,
  OutputAssembly := 101,
  => InputData => DeviceInput,
  <= OutputData := DeviceOutput
);

ABB-Specific Implementation Notes

EtherNet/IP not core ABB protocol. Used primarily in North American markets where Rockwell infrastructure exists. CODESYS-based implementation provides good interoperability. CP600-EIP module required for scanner functionality.
