Error code 256 with digital control tag

I created a digital control tag that is interfacing with an Allen Bradley Micrologix 1100 PLC with the DF1 driver. When I select the newly created button I receive an "Error Code 256" for this button. What does that error code mean? I have several other buttons on the same screen controlling bits in the same plc and without any issues.

The 200 series error codes are returns from the PLC itself. I don't see anything in the Rockwell documentation regarding 256 (0x100) so it may be new.

If you draw the Show Stats for the driver, does it indicate any error message to go with it?

What address are you trying to read?
