Hello folks,

I am trying to set the value in my OPC dynamic tag using this script, getting error 'Bad Not Found'.  
my tag path is correct and tag value quality is good but not sure how to achieve this.

Thanks

Have you tried copying the tag path directly, and see if there are any differences?

Never mind. Don't use _tag_ as a string when you try to write to it. 😉

```python
system.tag.writeBlocking(tag, 1)

```

Notice no quotes.

</div>

in my case all my tags are string like ,

CCV01  
CDC01  
CDR02

example it shows only Motor1,2,3,-----etc  
in my case it must be dynamic string value

Awesome, thanks you are correct @JordanCClark

there is one small correction in my script as it is binding from the container,

#Valve =1

Tagpath1 = "[default]Test/"  
Tagpath2 = "{event.source.parent.Valve}"  
Tagpath3 = "/Cmd.value"

tag = Tagpath1+Tagpath2+Tagpath3

#system.tag.writeBlocking(["[default]Test/+[str(event.source.parent.Valve)]+/Cmd.value"], [1])

system.tag.writeBlocking(tag, 1)

print(tag)

You can shorten the tagPath to one line using a format method.

```python
tag = "[default]Test/{}//Cmd.value".format(event.source.parent.Valve)

```
