Store process values to scada

Hello Mr. Cetkin

you can try to work with compressed taglogging archives to get aggregate functions or you have a look at this example:

Bye Murof

Hello ,

Dear friends ı need solution like Mr.Cetkin to store process values to scada

I use s71500 cpu and Wincc Professional or Wincc 7.5 as Scada in my systems

Problem is that ; I am logging process values from PLC to SCADA but some cases  when PLC and SCADA  connection aborted ( because of network problem or scada shutdown) process values cannot store to SCADA (SQL) in this case I want to store values inside of plc and if the connection state is healty then write back values to PLC to SCADA with releated timestamp and values(disconnected period of time and values)

I reviewed energy suite dokumantation above , Could it be solution to my case ? Values that I store are not energy based but could it use different way ?

As a result ı need solution to equlize PLC and SCADA values when connection disconnected

Thank for advice...

Split from I need a solution for energy values..

Mr. Cetkin

Greetings,

For power consumption values of a small power plant. There are about 15 feeders, I get the energy measurement values from all of them into SCADA in Accumulator type. I process and display them correctly, there is no problem in this part. But monthly, weekly, daily outputs or 15-day consumption calculation is requested. I have a solution, I share it below, but it is insufficient.

What is the fastest solution, the easiest solution or the most suitable solution for this?  In addition, are there different display methods of these transactions, such as calculating or outputting the consumption value between 2 dates.

Also, can you share if there is an official source or method for the ways you suggest.

"The solution I brought is running a script in the back. I have it calculate the difference over the same energy value with daily and monthly cycles. For example, I keep the value on March 1 at 11 o'clock, I calculate the difference of the value on March 2 at 11 o'clock and store it in a value. But every now and then the SCADA computer shuts down because of some problems that need to be prevented. The value I keep flies or is calculated incorrectly.  Or it can be difficult to read these values from the archive table. Obviously it is not a professional solution."

 Mr.Cetkin

Can you give me any information about your solution that you use in SCADA report?

Do you use report designer for reporting ?

How do you process monthly,weekly,daily values to store ? Are you store it seperate log cycle or use WinccOLEdb and VBS ?
