I am trying to identify the error on the "ReadHoldingRegistersRequest" error

I am trying to “identify “ the source of the error here. The magnifying glass has no information. I am looking to see and identify the source/tag of this error. I know its probably a data type mismatch or missing register.

Any assistance is appreciated.

If you turn that logger to TRACE we'll be able to see the request bytes and from there figure out the base register and length being requested. From there you'll have to figure out what tags that corresponds to.

If there is a magnifying icon I would think hovering over it provides at least the device name?

The Device name shows but when toggling “TRACE” nothing appears

You need to go to the gear icon, find that logger, and change the level there. The drop down menu you changed is just a filter.
