The SICK FTMg range of Flow Sensors support a number of protocols including an OPC UA* Server and MQTT, in this TechTip we'll be looking at getting data from a FTMG-ESD20AXX compressed air sensor using OPC UA .

First, make sure that you can login to the FTMG with sufficient user privilege to view and change, if necessary, the OPC UA settings. Within this set of options, you can set OPC UA to ACTIVE, change username, password, port number etc. - note, you will have to restart the service to commit changes to the security and port number etc (restart the service by selecting "INACTIVE" and then "ACTIVE". In our example, we are using no username or password.

**Please note that the IP address of the device used for producing this TechTip have been redacted at the request of our customer who kindly allowed us to produce this guide using their equipment.**

Start EasyBuilder Pro, choose the HMI model. In this example, we are using a cMT-SVRX-820. Click on "New Device/Server" and find the OPC UA client driver.

Enter the IP address and port number of the FTMg. The default port is 4840.

Click on "Security, Authentication...", as we are using no username and password in our example, the settings can be the default as shown below.

Click on "Tag Manager".

Check the string handling, and click "OK". You many find that you need to adjust this if you get errors with string data types.

Click "Get Tag".

This will show a warning dialogue. Click "Yes".

You should see this confirmation next, assuming you have the IP address and port set correctly. Click "OK".

Choose the Tags you wish to import. In our example, we are importing the "ProcessData" tags. Choose the selected items and click "Add Nodes".

Choose a Numeric object in EasyBuilder Pro and select the required tag. We have chosen "MassFlowRate".

Run "Online Simulation" and we should see the value for "MassFlowRate" displayed.
