Description
- How to scale data from a PLC in KEPServerEX (KSE) / ThingWorx Kepware Server (TKS)
- I created an OPC channel and I want to scale a tag.
- However, the scale option is blank.
- I set the tag to float (it's a raw 4-20mA signal)
- Is this possible? If so, what did I do wrong
- However, the scale option is blank.
- We have Temperature data coming in as integer with engineering range -43 to 1000
- We need to divide the value by 10 to get the actual value in one decimal point. How can we achieve this?
- If a tag value is varying between 1-500, User would like to make a separate tag that would only show values between 190 and 250
- Tag Scaling is not returning the expected values, User want 87 to show as 0.87
