Table 7.5 (Packet 4)
Tag Name Data Type Style Description
(If8h0 or Of8h0)Packet4 1 Packet4[8,1] NA Two dimensional array containing
packet 4 data for all 8 channels.
(If8h0 or Of8h0)Packet4[X,0] 1,2 Packet4[8,1] NA Packet 4 data for channel X
(If8h0 or Of8h0)Packet4[X,0].HartChannelID INT BIN Bits 0 to 3: Channel number (0 – 7).
Bit 4: Searching/Initializing HART device
Bit 5: HART communication failure or
device not found
Bit 6: Pass-through message pending
(ready)
Bit 7: Unused (0)
Bits 8 to 10: Packet ID
Bit 11 through 15: Unused
Date SINT[3] DEC Stored date in the field device
FinalAssemblyNumber SINT[3] DEC The final assembly number is used for
identifying the materials and electronics
that comprise the field device.
ExtendedStatus SINT[24] DEC The extended status returned by HART
command 48
Pad SINT[3] DEC Pad 32 bit alignment
1
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.
