Is there any way to avoid alarms with bad quality from being logged?

I have created an logged alarm report with the reporting tool, and i've been able to see that the duplicate alarms have the following features: Property "Reason of modification" = 16. What I have been able to find out this means that the quality of tag has changed. Therefore, "Quality" property of these repetead alarms is 20 (code hex: 0x14). This value apparently indicates "Bad - No communication, with last usable value - Set if this value had been set by communication, which has now failed." It is clear that the connection interruptions causes all these duplicated alarms. Furthermore, i have storage problems due to the amount of repeated data that are being logged and the dump files (over 2GB) generated by the constant warnings and error messages. ¿Does anyone have any way to avoid alarms with bad quality from being logged? ------------------------------------------------------------------------------------------ Split from Duplicate entries in alarm log.

I was not aware of that. But it would be good to know which version of WinCC Unified you are using. And also which device (PC Runtime or Unified Panel) you are using and which device version you have configured. Regarding your memory problems, I am wondering about dump files? Which dump files are created and where? Kind regards Stefan

Since there are no system functions that allow to edit sqllite files from wincc unified, and it is not possible to add libraries to js I went outside the scada environment. I have expertly crafted asked chatGPT to make a python script that given a folder looks trough the .db3 files present in the folder and removes any entries from the tables LoggedAlarm where change reason is equal to 16. I have chosen python since it is the only language where i know how to pack everything in a .exe without external dependencies. here is the python code: import os import sys import sqlite3 def delete_logged_alarm(db_file): try: conn = sqlite3.connect(db_file) cursor = conn.cursor() cursor.execute("DELETE FROM LoggedAlarm WHERE ChangeReason = 16") conn.commit() print(f"Deleted logged alarms from {db_file}") except sqlite3.Error as e: print(f"Error deleting logged alarms from {db_file}: {e}") finally: if conn: conn.close() def main(folder_path): for filename in os.listdir(folder_path): if filename.endswith(".db3"): db_file = os.path.join(folder_path, filename) delete_logged_alarm(db_file) if __name__ == "__main__": if len(sys.argv) < 2: print("Usage: python delete_logged_alarm.py <folder_path>") sys.exit(1) folder_path = sys.argv[1] main(folder_path) then i compiled it in a .exe, that i will now try to add to attachments, it is a split .zip, if you put all 3 file in a folder you should be able to open it. finally i call this application with the path to folder as argument from wincc, example as tested from a button: export async function Button_3_OnTapped(item, x, y, modifiers, trigger) { try { await HMIRuntime.Device.SysFct.StartProgram("C:\\Users\\Public\\rmv_changeReason_16.exe", "C:\\UnifiedArchive\\ALGDB\\HMI_RT_1_ALG260", 0, false, undefined); } catch (err) { HMIRuntime.Trace('fail'); } I have tried it and it works, seemingly without messing anything up in the databases. It goes without saying that I'am not responsible for any damages to any production environment. It has been done on my part as more of an experiment integrating external scripts in wincc unified. In our future systems i will most likely use a plc on LAN with the scada and push all the alarms to this PLC using S7 put. This script will allow me to clean up the logs as needed on already commissioned systems. @stefan_arcularius afaik it is the same behavior an any wincc unified, rt and ucp.

aem_a12 Joined: 8/3/2022 Last visit: 4/10/2025 Posts: 5 Rating: (0)	Hi Stefan, Thank you for your interest. I'm using Wincc Unified PC RT V18 Upd 3 with the same version configured (18.3). Regarding dumps files, these are of the type "GfxRTS.exe.22584.dmp" and are created in the folder "C:\ProgramData\Siemens\Automation\Logfiles\WinCC_Unified_PC\dumps". When the dump file is created, the alarm "ID 537264129 - Computer1: Manager is not connected " appears in the alarm viewer on RT. Also, an Application Error (Event ID 0) or (Event ID 1000) appears at the same time in Wndows Event Viewer. I saw this forum post [0] where "ender1adam" presented a similar problem, ¿Could you find out how this problem ended? Thank you in advance!

Regarding the multiple logged alarms, I cannot give you any advice yet. I would have to test this for myself first, but at the moment I am testing tag logging, not alarm logging. Kind regards Stefan
