Hello,

How can i get output of mbbiDirect record in form of bitArray ? Is there any record available in VDCT to get such output.

To get understanding of mbbiDirect record i tried following:

I have taken a decimal value (for eg.4 ) in ai record. This value is given as input in mbbiDirect record (for eg. bits). Now when i run ioc, i give command

caget bits.B0
 I get output as 1 i.e. just one bit of 100(binary of 4). then when I run caget bits.B1, i get output 0...same caget bits.B1 gives 0.
but as this mbbiDirect gives bit by bit output, i wan't to get output in form of bitArray.

My main requirement is i am getting output from waveform record as waf 4 50 66 64 51(this is the output which i have got from VME using asyn record )which i wan't to convert in binary or bitArray form. So kindly suggest me how to do it without code or even if I create a device support how will i fetch this data (waf 4 50 66 64 5)from VDCT to device support to create the logic.
