Hi Experts

I am new to Ignition. Currently playing with Ignition V8.0.0.

I was able to communicate the Ignition with S7-300 Siemens PLC through OPC and I am able to write and read tags to a DB. But when I write a value from a numeric text field on the Designer I get an error pop up

Although the write is successful the pop shows up everytime I edit the numeric text field. What am I doing wrong here?
