The move instructions modify and move its, and the logical instructions perform
operations on bits.
You can mix data types, but loss of accuracy and rounding error might occur and the
instruction takes more time to execute. Check the S:V bit to see whether the result was
truncated.
For relay ladder instructions, bold data types indicate optimal data types. An instruction
executes faster and requires less memory if all the operands of the instruction use the same
optimal data type, typically DINT or REAL.
The move instructions modify and move bits.
