EtherNet/IP

Set up the EtherNet/IP protocol for ENLYZE.

This guide walks you through connecting data sources that communicate via the EtherNet/IP protocol. EtherNet/IP is the open protocol based on the Common Industrial Protocol (CIP) that the Logix-generation Allen-Bradley controllers from Rockwell Automation use to communicate. ENLYZE connects these controllers via EtherNet/IP over Ethernet (CIP over TCP, default port 44818).

Symbolic tags instead of absolute addresses

EtherNet/IP addresses the data of Logix controllers through symbolic tags (named variables) rather than absolute memory addresses. The connector detects both controller-scoped and program-scoped tags and resolves composite data types (UDTs) down to their individual members.

Automatic variable detection

The EtherNet/IP protocol supports Variable Discovery. The controller's tags are detected automatically, so the memory addresses do not need to be known in advance.

Supported devices

EtherNet/IP is supported by the Logix-generation Allen-Bradley controllers, including:

• ControlLogix (1756 ControlLogix 5570 / 5580, GuardLogix)

• CompactLogix (5370, 5380, Compact GuardLogix)

• Micro800 (Micro820, Micro850, Micro870)

For a complete overview of the families and devices, see the Allen-Bradley page. The classic generations PLC-5, SLC 500, and MicroLogix address through PCCC and are not directly covered by the symbolic EtherNet/IP connector.

Required information

Information	Comment
Name	Pick a descriptive name for your data source
Edge Device used for the connection	Printed on a sticker on each Edge Device. Follows the pattern adjective-scientist
Machine	Each data source is assigned to exactly one machine
Manufacturer	Allen-Bradley
IP address	The IPv4 address of the controller. It must be reachable from the Edge Device
Port	Default: 44818 (EtherNet/IP, TCP)

1

Connect the data source to the network

If not already done, establish a network connection between the data source and the Edge Device. See Integration scenarios for the available options.

2

Create the data source

Open the ENLYZE Manufacturing Data Platform, select the machine you want to add the data source to, and click + Data source.

Enter the device details first.

3

Add connection details

To establish the connection and start recording data, enter the connection details.

Click Add connection details and enter the IP address and port. Then save the values.

4

Add variables

The EtherNet/IP protocol supports Variable Discovery, so adding variables is automated. The first Variable Discovery is triggered once the connection details are saved.

No data is recorded after Variable Discovery completes. You first need to select the variables to record. Follow our variable onboarding flow.
