Hi,
Never had similar situation but I would try to do it like below:
1. Create Input Global variable (373 bytes)
2. Register this variable in EIP TagSet setting (only input, output leave blank)
3. Assign originator variable (only input)
4. After "Rebuild Controller" Sysmac studio shows no errors or warning so it should work.
5. Transfer Config to controller
I don't have a physical PLC right now to check it so it's just a possible solution.
