Hello dude,
I have question about Read_Var function blok. How to read register x1 (%I). I am still confused because the output of this function is Array of INT while we want to read Bit/Binary register. I hope you will answer my question. Thank you

dear i have one project, in it i have to read the Power, voltage and current from power meter PM5100 And i am using P342020.
once i used the read var, i am able to read the register which are in integer data type but some register which having float 32 bit data type giving the raw values.
As in power meter there is 200 kw but in plc it show 15780 value.
can you know about it that how i can solve it
