rguzmand Posts: 2 Rating: (0)	Hello: I have the WinCC 6,0 4 SP and DataMonitor V6.1 softwares. I need to conduct mathematical operations with stored variables in the TagLogging, for example to add the data of tag between days 12th and 13th of this month and to keep that data in an internal variable. What is the best way to conduct that operation? Any help it will be appreciated rguzmand

Perhaps you can already do the big part of your calculation in your S7 and then write the calculated values in your WinCC archive e.g via AR_SEND? http://support.automation.siemens.com/WW/view/en/23629327 nemo

Lamentably in this project the PLC is provided by others, which we only connected by OPC, reason why, it is necessary to make it in script. Nowwe needto recover the values of the internal variables after restarts WinCC. The support service said something abouta CD of WinCC Knowledge Base (ID 22014563), but I have not been able to obtain it. Do you know another way I can obtain the Script of which they speak in the Help?. Thanks again rguzmand [;)][;)][;)]

This tool can be provide the sum of value between two periods, and you can store the value of sum in a tag of WinCC. See these posts: /tf/WW/en/Posts/781 /tf/WW/en/Posts/1487 /tf/WW/en/Posts/3930
