What does the register instruction PR[5,3] = PR[5,3] + 200 do?

What does the register instruction PR[5,3] = PR[5,3] + 200 do?

• A. It decreases Z position register 5 by 200
• B. Adds 200 millimeters to Z position register 5
• C. Sets Z position register 5 to a fixed value
• D. Increments Z position register 5 by 200

Answer: (B)

The register instruction PR[5,3] = PR[5,3] + 200 is designed to modify the value contained in register 5, specifically at the bit 3 location, by adding 200 to its current value. This operation effectively increases the numerical value associated with the Z position register 5 by 200 millimeters. In FANUC programming, the PR command refers to parameter registers, which are used to store various operational values. The arithmetic operation being performed indicates that the current value in PR[5,3] is being incremented, but it is critical to note that the instruction specifies an addition rather than a subtraction or assignment of a new fixed value. As a result, the operation aligns with the concept of adding a defined increment to a register's existing value, leading to the conclusion that this operation adds 200 millimeters to the Z position register 5.
