How can PROFINET variables from PLC application be mapped into the data layer

Hi,

I have successfully set up a PLC project to connect a PROFINET device and when I start the project I can see the current PROFINET values.

Now I want to map the PROFINET values of this device into the data layer so that I can later on store the PROFINET data via NodeRED in an INFLUX DB.

Is there any documentation on how to do this easily?

Hello,

If the data is in variables in the PLC app, then the only step necessary to get this exposed to the data layer is to go to the Symbol Configuration page in PLC Engineering, and select the variables you wish to display. It is recommended to put the variables you wish to expose into a global variable list (GVL) so they show up in the data layer under a single point.

This how-to covers it in more detail: https://community.boschrexroth.com/ctrlx-automation-how-tos-qmglrz33/post/set-up-a-ctrlx-plc-project-to-publish-variables-to-the-ctrlx-data-layer-nwOEEXM6MRY4thp
