Offset Content Description

33 Current Command This field contains the index of the current command

to execute.

34 Command Request Count This field contains the total number of request

messages issued on the port.

35 Command Response Count This field contains the total number of response

messages received from devices on the network.

36 Configuration Error Word Configuration error word (see table).

37 Current Error Code Current error code for port.

38 Last Error Code Last error code reported for port.

61 to 248 Reserved Not used.

249 Read Block ID Block identification code of 0 or -1 to indicate a status

data block.

The following table defines the contents of the configuration error word. Each bit

in the word corresponds to an error condition recognized when the module is

configured. There is a separate word for each application port. This data is

reported in the status data area previously defined.

Bit Code Description

0 0x0001 Enabled not set to Y or N

1 0x0002 Enable Handheld not set to Y or N

2 0x0004 Primary Master not set to Y or N

3 0x0008 Invalid Preambles (1 to 50)

4 0x0010 Invalid Short Address Retries (0 to 50)

5 0x0020 Invalid Long Address Retries (0 to 50)

6 0x0040 Invalid Retries After Error (0 to 50)

7 0x0080 Invalid Poll Time After Error (0 to 10000)

8 0x0100 Invalid DB Address Status

9 0x0200 Invalid Command Count

10 0x0400 Memory Error in allocating commands

11 0x0800 Memory Error in allocating command fixed data

12 0x1000 Memory Error in allocating TX/RX buffers

13 0x2000 HART Board not found

14 0x4000 Cannot initialize HART channel

15 0x8000

Each command in the command list for each HART channel has a word value for

a status/error code. This error data list can be read using the

Configuration/Debug Port and can be placed in the module’s internal database

using the Error/Status Offset parameter for each port. Accessing the Debug

capabilities of the module is accomplished by connecting a PC to the Debug port,

then running a terminal emulation program. This status/error code is the first

word of the Integer Data Block returned from every HART command executed.

This word has information about the execution of the command by the HART

device.
