can you be more specific what your binary output should be? There are conversion FBs as defined in IEC 61131-3.

Also in the IEC 61131-3 directory you can find logic operator FBs.

But from my experience it mostly is better to define own simple or basic FBs for such functions.

The ng-modulebus is for tcp/ip, but i need to use rtu, so i used the old modbus module, i read the value of I/O status which is integer, such as 255 is 11111111, 65535 is 1111111111111111,
i use modbus[rtu:/dev/ttyS0:115200:N:8:1:2000:3:1:0..1:0]
and the value is 65535, that means the output value is 1111111111111111, that means all the 16 output are on,
i need to convert 65535 to 1111111111111111, and according to the place to do some logics,.
actully, FB_AND in iec61131 i input In1 as 137, input In2 as 1 but the out is 0

ah so you need a bit representation in the string. I think here the a ST algorithm and generating an according string is better.
