The final assembly number is used for
identifying the materials and electronics

co mma n d 48
Pad SINT[3] DEC
Pad 32 bit alignment

The name in parentheses represents the module tag name (i.e. If8h0 or Of8h0) depending on w hich module is being used.
2
X represents the module channel number (0 to 7)
Note: Not all of the data that is returned by the process outlined in figure
7.5 gets passed to the packets. In order to access the data that is not
passed to the packets, you must execute the appropriate HART message
using the pass-through command, which will be discussed later in this
chapter.
