The result of energizing the ADD instruction is placed in which part of the instruction?

The result of energizing the ADD instruction is placed in the destination file. In programmable controller systems, the ADD instruction takes two source values and processes them to produce a sum. This sum needs a defined location where it can be stored for future use or reference. The destination file serves as that location, effectively holding the result of the addition operation.

Each instruction in programmable logic controllers (PLCs) typically need to specify where the outcome of the operation will be saved, and the destination file is the designated area for this purpose. The source file, by contrast, is where the input data is retrieved from, and the tag identifier is simply a means for identifying particular instructions or data points within the programming environment. The instruction type pertains to the specific operation being performed but does not indicate where the result is stored. Therefore, the destination file is the correct choice for where the result of the ADD instruction is placed.
