So I'm working with TIA Portal 15.1, and I'm working on an update for the HMI. When I go to update the Device Proxy data, it's still fine. I then am updating 2 HMI alarm descriptions on the HMI side. I then go to compile and do a rebuild all on the software. This error always comes up afterwards. Can someone help, not sure why this is happening.

Hi NJaqua,

To try to solve your error:

open Simatic Manager project
Then open Hardware editor
Select Options -> Report System Error
Then "Delete" button and - if RSE is needed "Generate"
update Proxy PLC in TIA project

Hi,

I attach documentation:

Search Report System Error: Programming with STEP 7

I hope this help you
