## New topic created by moderator, because original question was answered. Colleague has problem to start up project with PP65, with error in the logger CPU mismatch. ![WhatsApp Image 2025-03-11 at 13.58.06](https://europe1.discourse-cdn.com/brcommunity/original/2X/c/cc048b786fa742204f7bad833edcb525bd83be46.jpeg) is this part of booting? because it’s been more than 2 minutes I’ve been waiting but there’s no change ---

Hello, the PLC is in [Service mode](https://help.br-automation.com/#/en/4/automationruntime%2Foperationmethode%2Foperationmode.html). Please check this [Community topic](https://community.br-automation.com/t/why-controller-is-going-in-service-mode/1594). ---

This is not a PLC, just a HMI. I just tried to program it and do an offline install using CFcard. ---

[PP65 is both a controller and an operator panel](https://help.br-automation.com/#/en/4/hardware%2Fpowerpanel_65%2Fpp65_panels%2Fpp65_features%2Fkompakte_losung.html). Please check the logger to find out the reason of the Service mode. ---

oh so it turns out this power panel is like a PLC + Monitor? not like HMI in general? ---

But here I tried to connect this power panel to automation studio, nothing was detected in the automation studio application, it didn’t read that there was a connected device, so I used the offline program installation method using CFcard ---

Hello, you can browse for a PLC in AS Online Settings. The prerequisite is [to activate SNMP](https://community.br-automation.com/t/browse-for-targets-in-as-not-working/2065). If you don’t know a PLC’s IP address you can look for it [using Wireshark](https://community.br-automation.com/t/determining-a-plcs-ip-address-using-wireshark/495). ---

I am still confused and have not found the answer here, because my PP65 is said to be in service mode and I am confused about how to return it to normal mode, because here it is different from the PLC x20 which has a reset button on the device, whereas here there is no button at all ---

Hello, The PP65 is in Service mode for some reason that can be seen in the Logger. You can open the logger in Automation Studio if you’re connected to a PLC. If you can’t connect, you can insert a CF card into a card reader and look for the data partition in the RPSHD\SYSROM\ folder. There should be BR modules, which are actually loggers. ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/2/258d6e54f697eabb37aa6ddf0e7857e3b56cddc9.png) These BR modules can be opened in the logger view in Automation Studio. The reason for the Service mode should be in the ARLOGSYS.BR. Without checking the logger, you won’t find why the PP65 is in Service mode. ---

After I checked the logger, it appeared like this, lots of errors ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/7/758737218b497118c2a858a0ed11374e72c9c0eb.png) ---

Since you have a CPU mismatch, it is obvious that the hardware selected in your project and downloaded to the PP65 does not match the actual hardware. Please ensure that the proper hardware is selected, as the full model number is important. ---

You can find the hardware upgrade here: [4PP065.0571-P74 download](https://www.br-automation.com/en/downloads/v40-hw-upgrade-4pp0650571-p74/) After download you can install it via the menu Tools-Upgrades where you can select the tab Local. Browse to the downloaded file and install. Then it should be available in your toolbox (in some cases a restart of Automation Studio is necessary). ---

I have upgraded, restarted the automation application and restarted the PC but it still doesn’t appear in the hardware catalog ---

Did you upgrade using Tools-Upgrades or by executing the .exe file? Can you create a new project with the newly downloaded hardware? ---

Without proper hardware, you cannot create a functional project. From the community’s point of view, we have done our best for you. I think you need to get in touch with the support team at your local B&R office. They can connect with you and help you with the installation. ---
