What address patterns are used for Position Variables?

• A. #P000 through #P127, BP000-BP127, EX000-EX127
• B. P1-P128
• C. P000-P127
• D. P0-P127

Answer: (A)

Position Variables are addressed using a prefix that identifies the type of variable and a fixed, zero-padded index from 000 to 127. The valid forms are #P000 through #P127, BP000–BP127, and EX000–EX127. This means there are 128 entries in each category, and the three prefixes indicate different namespaces or contexts for the same kind of data. Using zero-padded three-digit indices keeps the addressing uniform and predictable across programs.

So, this pattern is the best answer because it accurately captures the standard ways to reference Position Variables in Motoman programming: a three-digit index with the appropriate prefix, covering the 000–127 range for each prefix. Other formats like P1-P128 or P0-P127 omit the required prefixes or the fixed-width indexing, which don’t conform to the documented address schemes.
