This is a group of register accesses similar to the ReadAnyGroup that ensures that the data consistency of multiple variables matches. The consistency is verified using an algorithm based on the VersionNumber of the register accesses.

You can use the constractor or the add function to add variables that you want to be consistent.

To check the consistency, you have to transfer the TransferElementID of changed variable by calling the DataConsistencyGroup::update() function. If the VersinNumber of all variables are consistent, this function returns true. If you trnasfer an TransferElementID that does not consist to this group, it will be irgnored and this function returns false.

The same TransferElement can be part of multiple DataConsistencyGroups at the same time.
