Hello Experts,

I need help with the following issue I'm facing in my current project setup:

• PLC: Siemens CPU 1510SP-1 PN
• HMI: WinCC Runtime Advanced (PC Station)
• TIA PORTAL V20

I’ve designed a report for printing alarms. To configure it, I Created Report page layout and drag & Dropped the Alarm View fromToolbox > Controls, selected "Alarm Buffer "as the data source, and completed all necessary settings to the best of my knowledge as shown in the attached screenshot(Right side)

From the HMI, I provide the Start and End Date/Time(using DateTime tags), and trigger the print function through a button event configured to "Print Report".

Problem:
When I print or save the report as a PDF, the output is completely blank as shown in attached picture(Left side), even though the alarm buffer is populated (I have confirmed alarms are present and visible on the runtime screen). Strangely, I also created a separate report for flow readings, and that one works perfectly and displays the correct data.

• I am connected to the live plant PLC and online with the process.
• Alarms are confirmed to be active and visible in the alarm display during runtime.

Can anyone guide me on what I might be missing or doing incorrectly in the Alarm Report configuration?

Thanks in advance for your support!

 

Temporarily remove the Date/Time filter tags and regenerate the report to check if any data appears. If it works without filtering, the problem lies in the tag values or format.

Thank you so much for your reply.
I tried what you mentioned but no success.

One thing more, I don't have License for WinCC RT Logging and when I runt my HMI on Runtime, it give me warning of absence of mentioned license. Isn't it because of this Licenses absence. Remember that I am trying to pick alarms for Reporting from Alarm Buffer. Does Alarm buffer have any relation with Wincc RT Logging License and also, does the Alarm buffer Reporting need any license?

 

Does the Alarm Buffer require a license?
No, for normal viewing on HMI screen — it’s built-in.

Does the Alarm Buffer Reporting need a license?
Yes, effectively — for it to work reliably in reports, WinCC Runtime Advanced Logging license is required (even if you use Alarm Buffer instead of Alarm Logging).

Obtain and install a WinCC RT Advanced Logging license. Even a basic license unlocks proper functionality for alarm reporting and historical views. Check Siemens product: 6AV2103-0DB03-0AK6 or equivalent.

Thank you so much for your support. I will obtain the mentioned License and will then try again.
