Hi all,  
I am not able to write string "TANK" or "SEALING PLATE" to a tag named "LoadType" using the another tag's value changed script. Basically wat I want is to enter the above mentioned strings to a tag after checking the value of a tag. The script I developed works fine in the Script console. Can anyone help me out?

Does your gateway have the Edge Compute plugin? Tag event scripts won't run without it, I believe.

How can I check whether it is present or not?

Check the gateway webpage. I don't have an Edge license available to show a screenshot, but the status or config pages should make it pretty clear.
