SiDirect reading array from S1517 Siemens PLC

Dear colleagues,

I try to read an array of INT from S-1517 Siemens PLC with SiDirect (version 2020.1207.3628.2) using syntax 

PORT.PLC01.DataBlock.Unit.Tag[]

and I get only first INT value in my Client, in SMC console I see that

Read status = pending

Value = [empty field]

Type = VT_I2 - 2 byte signed int

Quality GOOD: Nonspecific: Not limited

Is it possible to get array of all values in one tag?
