Which tag component identifies the function of the data, such as fault or data?

• A. Location
• B. Member
• C. Bit
• D. Slot Number

Answer: (B)

When a tag represents a complex data type, each piece of data is organized into fields that define what that piece means. The field that names what the data represents within the structure is the member. It tells you the function or role of that portion of the tag, such as a fault indicator, a data value, or a status flag. This makes it possible to access the exact piece you need, for example tag.member to read the specific fault code or measurement. Location points to where data is stored, Bit is a single binary value, and Slot Number relates to hardware addressing. Those pieces describe where or how the data is stored, not what the data represents.
