[VTS.En] is the logic setting of the protection voltage transformer supervision function;
[50/51SEF.En_VTS_Blk] is the logic setting of the function which can block all the SEF
protection that relate to the voltage measurement when the voltage transformer is failed;
[BI_En_VT] is the binary input for denoting the local VT is in service;
[VTS.Alm] is the alarm signal of the protection voltage transformer supervision.
