Use an SQLTag from a PLC in a script?

Beginner question: What is the proper syntax needed to add 10 to an SQLTag value in a script?
It’s a global Event script, Timer type.
Simply putting the tagname in the line does not work: simTankLevel = simTankLevel + 10
Searched all the keywords I could think of. Probably won’t know the correct search keyword until I know the answer… :slight_smile:
Please point me to an example if one is available. Thanks, Vic

In a python script you need to use a function to get and set tag values.

value = system.tag.getTagValue("[]mytag") system.tag.writeToTag("[]mytag", value+10)
You can take a look int the manual under Scripting->Python->API References->system.tag to see all the the functions available for working with tags. If you search for ‘write tag’ in the manual it’s the second hit.
