The actual temperature value is incorrect but the value coming from the sensor is correct. There is a discrepancy between the DB value shown in OB1 compared to when i view the value in the data block. I followed the same process for all other values in the DB without an issue.

For now i am using memory bits to get around the issue. We are not able to see the whole of network 2. We cannot see all the entries in the DB. What I can see is that the 2nd call of FC6 receives an input that would lead to the answer given in the DB. What is the tag name & its value of the output in the 2nd called FC6? If you have Step7 V18 or V19, you might have a bigger problem and need to patch your software. But you need to talk to Siemens by using the Support Request link. It is vital that you speak with Siemens, since I think they are only aware of SCL issues.
