Bad Tag quality on Modbus RTU over Serial link

Hello to all, thank you for reading the post. I am having trouble with tags from a Direct Logic 05 - D0-05DR connected via Modbus RTU over Serial to Ignition Maker ed. version 8.1.7 OPC-UA server running on Windows 10. The PLC device shows a “connected” status and the diagnostic tags show “good” statuses however no manually created tags have been passed to Ignition successfully. Here are some images that will show the exact errors coming through. - Any help on this is Greatly appreciated!
