try to switch OFF an ON the cpu.

Do you have only cpu? Or is a operating unit with I/O connected?

In this case, the program inside is running or not?

Could you access to the cpu with Control Builder / Automation Builder?

One photo of the unit could give more info about the issue

If you give us more information, we can help you better

I am working with a CPU only, the program is running but is not showing nothing on display, no error, no status...is blank. I can access to CPU with Automation Builder 2.0

Ok, and in status do you have any indication of error in cpu?
One other possibilities is that the cpu have the display damaged/broken ....

Pay attention that the old FW version of PM573 cpu are not simple updated to the last version of FW.This is not depending of Automation Builder but only of FW of cpu

But the FW comes with the installed software, in this case Automation Builder. What other test can I do?

None...but if the display stay blank, probably it's damaged

Hi,

One reason could be that the display firmware may be missing. This may happen if an attempt was made to update the firmware via automation builder. If the CPU is older and the firmware version can be determined, you could attempt to load the correct firmware via SD card.
I had once resolved a similar issue with the display for an older CPU using SD card method.

I believe the firmware zip files for PM573 PLCs are still available for download from the ABB website.

The ability to make updates or not depends on how old is the CPU you are analyzing.

One possible old FW version 2.3 at the follow link:

Hi,

Loading firmware via SD card may help resolve the issue with the display firmware.

Download the firmware from the link in the text file .

Search for 1SAP190800R0252 released on 25-04-2016. In case you know the year when the CPU was manufactured, you could also search for newer/older versions as well.

Download the firmware zip file and prepare an SD card. Once the SD card is prepared and SDCARD.ini file appropriately modified, you can proceed with loading firmware via SD card.

PFA SD card firmware update procedure pdf only for reference.

Good Luck.

Regards

Rahil
