How to simulate Logs on WinCC Unified Project

Hi,

Could you please describe your requirements and system in more detail?

• Which version of WinCC Unified, which device and in which device version are you using?
• What exactly do you want to simulate?

Kind regards
Stefan

Thanks for your help.

What i have ;

An array of data generated by an PLC ,  where I save values of Torque and Position recorded at every 10 ms.  This an cyclic event that happens at every 25 seconds during 1 second.  The array has 200 positions/elements.

What I would like to have;

-Save the array values from the PLC , into an HMI, Siemens unified comfort ,   and Export the Array values to external CSV file in SD card. 

Where to start ?    

Regards.

I could reduce to 100 tags and make individuals tags  , no problem. So, i could than use the tags has source of trend Axis ? 

After having Trend of the 100 tags , making a profile /  curve i could use "screen.item ..."  commands  to trigger from the PLC the Chart Button export ?

Makes any sense what i am describing so far ?

Regards,

MD

Hi,

I am not sure if I understand you correctly. If you want to archive tag values that change on a 10 ms cycle, this would not be possible.

However, as I understand it, you want to archive 200 tags every 25 seconds. That would be possible. Unfortunately, you cannot use the Array data type, so you would have to create 200 individual tags in the HMI. Probably the "on demand" logging mode would be the best for your use case.

Even if you plan to use a Unified Comfort Panel, you can test it by simulating the runtime. But only until you get to the point where you want to write the logged tags to a CSV file. There you have to specify the target path, which will be different on the panel (Linux-based) and on your Windows PC.

Kind regards
Stefan
