**Description:**
**How to check the current firmware version installed in the controller?**

**Solution:**

The only option to check which firmware version is installed on the controller is to check it from the PR Master software level. [PR Master](https://www.roger.pl/en/support/technical-support/download/software/pr-master-racs-4-system-management).

After PR Master is launched, in the main window, in the networks tree, left mouse click on the controller. Alternatively one can use top menu: *System* > *Networks* > *Controllers* > *Properties*.

In *Controller Properties* window, *General*, bookmark, the controller firmware is shown.

Please note, that to be absolutely sure if displayed firmware is accurate, we suggest to perform controller restart before firmware is read. In order to do this click right mouse button on controller and select *Restart controller and verify version* command.
