Recommended Action
Change the tag address so it is the following format:
I:<word>/<bit> or O:<word>/<bit>
where <bit> is required for Bit and Bit Array.
The Tag Address should have a numeric word offset.
Add a slash and bit number to the Tag Address
Change the bit number to a value between 0 and 15.
Change the Tag Address so it begins with an O.
Change the Tag Address so it begins with an I.
The word offset in the Tag Address must be less than the Input
Size specified on the Communications Setup Dialog.
The word offset in the Tag Address must be less than the
Output Size specified on the Communications Setup Dialog.
The Data Type implies that the Tag Address should specify a
bit number.
The Data Type implies that the Tag Address should not specify
a bit number.
Change packet bytes to 1-128 bytes.
This tag must be manually edited to the DeviceNet protocol.
DeviceNet node addresses must be 0-63.
Reduce the Bit Offset.
Uncheck the Write Tag box on the Tag Form.
Check the Write Tag box on the Tag Form.
Modify the Tag Address to begin with I or O.
An Assembly Instance can only be assigned all input tags or
output tags. Place input and output tags in separate assembly
instances.
Increase the input or output size on the terminal setup screen.
Add a colon : after the I or O.
Adjust the Bit Offset on the Tag Form.
Reduce the word offset for the associated Tag Address.
