  • How to set up an OPC connector in Tulip

If you have a functioning OPC UA server with tags that you would like to connect to Tulip, then you are ready to set up an OPC UC connector and create your first machine monitoring app.

Please note: this article will cover machine monitoring for standard Tulip accounts hosted in the cloud. If you deploy Tulip on premises, you will need to speak to a Tulip representative to use machine monitoring.

Setting Up An OPC UA Connector

First, click into the Machines option under the Shop Floor tab on the Menu Bar.

Then, click "Machine Data Sources" from the dropdown in the top left.

Then, click “Create Connector” from the Machine Data Sources page.

Name your connector and hit "Save"

Then click the new connector from the list of OPC UA connectors.

Configuring the OPC UA Connector

After that, you will have 4 new fields to fill in:

  • Running On

  • Agent URL

  • Security Mode

  • Authentication Method

"Running On" Field

For the “Running On” field, choose “Cloud Connector Host” unless you have a special setup that you have discussed with a Tulip representative.

"Agent URL" Field

For the “Agent URL” field, you should have a local TCP server with an IP address and port. If you are using a service like Kepware, this will be exposed in the UI. For example:

opc.tcp://192.164.54.1:49320

Then, if your server is local, you will need to add a redirect so that cloud services can access this IP address. Here’s an example of a redirect that is accessible in the cloud:

207.172.213.113/opc:40534

Depending on the OPC UA endpoint available at the indicated server, configure the “Security Mode” and “Authentication Method” fields.

"Security Mode" field

Choose a “Security Mode”. Pick either “Sign” or “Sign&Encrypt” to sign or sign and encrypt the connection made between Tulip and the OPC UA server living at the indicated “Agent URL”.

If choosing either “Sign” or “Sign&Encrypt”, you must then choose a “Security Policy” and provide both a “Private Key” .pem file and a “Certificate” .pem file in the text boxes that appear below:

"Authentication Method" field

Choose an “Authentication Method”. The “Anonymous” method opens a session on the OPC UA server without authentication. The “UserName” method authenticates a given user via the provided “Username” and “Password” fields.

Similarly, you can generate a certificate and private key pair of .pem files for a user on your OPC UA server, select the “X509” method, and provide them in the “Certificate” and “Private Key” text boxes to authenticate.

Testing your Connection

Hit “Test” to see if you can successfully connect to the server.

If the test is successful, then you are ready to set up a machine. Click "Save", and then go to the "Machine Types" page to set up your first category of machines.
