How to Log the Data of Type String in 800xA Log Configuration
Please suggest how to log the String data in 800xA Log Configuration from the OPC.
I'm not sure what you meant to do. I guess you get a string via OPC and you like to convert it to a integer/real value to log it in 800xA.
You can add a Property Translation Aspect to your object. There you define a property of the datatype you need e.g. VT_I2 (short integer) and name it e.g. TEST. In the expression you convert your string value from the control connection. This TEST Property will you now find in the Log Configuration where you can log it with the desired template.
