May I suggest that you setup a SVE on the FP target linking to the FP tags. Then you can programatically update the scaling parameters from the attached PC (its not possible directly on the cFP target, since this target does not support the write properties for updating scaling params. etc ).
As of ver. 8.6 scaling of tags on a SVE on a cFP target is possible. This was not the case with previous vers. of LV 😞
It works great !
