Hi. Your image is not great quality. Can you post the logs as text?

Additionally, you pasted the function code without putting it inside of a code block (see canned info below). I've tried editing your post but your function code is pretty much messed up due to not having it in a code block in the first place. Can you correct that?

Next, can you tell us what type of PLC make & model?

Other information that may be useful would be the node.js version you're running on?

### canned info

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote `````)

````auto
``` 
   code goes here 
```

````

You can edit and correct your post by clicking the pencil ✏ icon.
