Back up a moment:

What do you mean by “mode” ?

- Connection type? (OPC/UA versus Ignition’s driver)
- Subscribed versus polled?
- Subscription/poll pace?
- Data types/transforms?

Or do you mean traffic in the other direction? (Writes to the PLC.)

I think we’re struggling with English here. Can you post a screenshot of what you are trying to change.

1. What is the setting now?
2. What do you want to change it to?
3. Do you want to do this just once or do you want to be able to change it by script?
4. Where are you stuck?

Yes you can set that to the polling by setting scan class of the tag. There is a default scan class present that gets assigned to every tag initially.  
You can create new scan class, set it’s mode to polling and assign that to your tags.
