Status bit of structured variable

Status bit of structured variable

Hi,
I have created a DNP3 structured variable. I am trying to get the invalid bit status of a sub variable of the structured variable in straton using "VSIGETBIT" Function block. But the output of the block is FALSE even when there is communication error. (output is TRUE if i connect a normal variable i.e., a non structured variable). Is there any other way to get the invalid bit status of the sub variable of the structured variable?
TIA
