Allen-Bradley ControlLogix Ethernet Driver Help
Solution:
Change the tag's data type to one that is supported. For example, data type Short is illegal for a BOOL array
Controller tag. Changing the data type to Boolean can remedy the problem. In response to this error, the tag is
deactivated and is not processed again.

Unable to read tag <tag address> on device <device name>. Data type
<type> not supported. Tag deactivated.
Error Type:
Warning
Possible Cause:
A read request for the specified tag failed because the client's tag data type is not supported.
Solution:
Change the tag's data type to one that is supported. In response to this error, the tag is deactivated and is not
processed again.

Unable to read tag <tag address> on device <device name>. Tag does not
support multi-element arrays. Tag deactivated.
Error Type:
Warning
Possible Cause:
A read request for the specified tag failed because the driver does not support multi-element array access to the
given Controller tag.
Solution:
Change the tag's data type or address to one that is supported. In response to this error, the tag is deactivated
and it is not processed again.
