Scaling tags in Kepware Confugration.

I have temperatures 10 times higher than they should be. I read the article "How to scale data from a PLC in PTC Kepware Products" (https://www.ptc.com/en/support/article/CS291338). It resulted in a tag that errored out with a CIP error 0X5.

I created the new tag, gave it a name and description and the address. and set the Scaling to linear, 0 to 10000. And got the error. I tried changing the data type from Word to Float and Short, but they threw the error for illegal data type. 

 

Any other suggestions?

I ended up handling this in the program I am writing to consume the data. There is no clean way to do this. It is going to require a switch case and go from there. I may be able to talk to the machine vendor and see why there is no consistency in the PLC valueYes, when I'm dones. 

 

I am just marking this as solved to close it out.

Linear scaling should be configured as shown to yield the results you are looking for.

You can also swap the raw high and scaled high settings for the reverse.

Thanks Andy,

 

But that's exactly what I did and it gives me the error as shown in the original post.

Please create a case and send us your project file so we can take a look and see what might be amiss. Indicate which tag specifically isn't working as you expected.
