How to setup a connection between the Etherline® Guard and the ctrlX CORE X3

Data connections are are the backbone of modern machines. In most cases factory infrastructure is established by Ethernet cables. A proper function is thus crucial.

Moving cables in drag chains or robot applications don't last forever. After having performed a certain number of bending cycles, a reliable communication cannot be guaranteed any more. The Etherline® Guard is our answer to monitor the health status of your cable. This allows you to react before data loss occurs, which decreases the availability of your network, in the worst case lose the communication.

Use the Etherline® Guard as a predictive maintenance device to continuously monitor and report the Ethernet cable health status and a ctrlX CORE to process this health status to ensure availability of your system.

Use the How-to to easily set up your system step-by-step using Node-RED.

Prerequisite

  • ctrlX CORE X3

  • Node-RED App for CtrlX Core including license

  • Lapp Etherline® Guard with firmware V1.04.016 or newer

  • Network connection between CtrlX Core and “LAN” Port of Etherline® Guard

 

Step-by-Step guide

Step 1

Log into the web server of the Etherline® Guard using your web browser with the de default IP address “https://192.168.0.32” (factory default).
Confirm a non-private browser connection, since there’s no certificate installed yet.

Step 2

Set a password with a minimum length of 8 characters

Step 3

Set an IP address in the same subnet as the CtrlX Core.

Now all configuration of the Etherline® Guard is done. Continue with the settings of the ctrlX CORE.

Step 4

Log in the web interface of the ctrlX CORE.

Step 5

Launch the flow editor of Node-RED.

 

Step 6

Import the sample project “Etherline_Guard.json”.
From the menu choose “Import”.

Click on the button “select a file to import” and select the file.

You will see a new project.

Step 7

Modify some settings to your individual configuration.

With a double click on the single nodes (inject Login Data, HTTS Login and HTTP Request Status) you can modify the parameters.

  

Adjust password to the password for the Etherline® Guard which you set in step 2.

 

Adjust IP address of Etherline® Guard as you set in step 3.

 

Adjust IP address of Etherline® Guard as you set in step 3.

 

Step 8

Deploy your program onto the ctrlX CORE.

 

Step 9

Open the Node-RED dashboard to see the values.
