If a material balance system is used these variables are used to set and monitor the deviation from the set mixing ratio of component A and B.

MaxDeviationMixingRatio is writeable by the client and used to limit the maximum deviation in percent.

TargetDeviationMixingRatio: This deviation (in percent) is set/used by the material balance system

ActualDeviationMixingRatio: Actual deviation (in percent)

The values are given related to the mixing ratio of component A. If the maximum allowed mixing ratio is 51% component A and 49% component B MaxDeviationMixingRatio is 1%.
