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!

Thanks for Reply. Attached is the header screenshot for your reference.

Furthermore, Time range is correct and I also Tried without time range.Like I removed Time range tags and tried but same issue.

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?

Appreciate your reply. 

I haven't tried with system Alarms, so can't say anything about that.

However I got reply from another forum and expert from there says, that Logging License is required . So for now to go ahead, I will acquire license and will try again. let see, what's waiting next. 

Attached is the link of mentioned another Forum reply for reference.
