3. HART Introduction

3.1 Analog and Digital signal

The HART communication protocol is based on the Bell 202 telephone communication standard

and operates using the frequency shift keying (FSK, Figure 14) principle. The digital signal is

made up of two frequencies - 1,200 Hz and 2,200 Hz representing bits 1 and 0, respectively. Sine

waves of these two frequencies are superimposed on the direct current (dc) analog signal cables

to provide simultaneous analog and digital communications (Figure 15).

Figure 14: FSK signal

Figure 15: Analog and digital signals

HR

T-710 / HRT-310 User Manual Version 1.31 Page：

23

3.2 Network topology

HART bus can operate in one of these two network configurations—point to point and multi-drop.

1. Point to Point Mode :

In point to point mode, the analog signal is used to communicate one process variable and the

digital signal gives access to secondary variables and other data that can be used for operations,

commissioning, maintenance and diagnostic purposes. Only one HART slave device can exist in

HART bus and the polling address must be zero.

Figure 16: “Point to Point” topology

2. Multi-drop Mode :

In multi-drop mode, all process values are transmitted digitally. The polling address of all field

devices must be bigger than 0 and between 1 ~ 15. The current through each device is fixed to a

minimum value (typically 4 mA). The maximum HART device number in HART bus is up to 15.

[ Note ]

1. The built-in resistor in HRT-710 is 250 Ohm with 1/4W. Therefore, HRT-710 supports to

connect the maximum 7 HART devices simultaneously. If the HART devices in multi-drop

mode are more than 7, then users need to disconnect the built-in resistor in HRT-710

(prevent to burn down) and use the external 250 Ohm resistor with 1W.

2. The built-in resistor in HRT-310 is 250 Ohm with 1W and it allows up to 15 HART devices

to be connected.

3.3 HART Frame

The HART frame format is shown as below:

Figure 18: HART frame format

3.3.1 Preamble

All frames transmitted by HART master or slave devices are preceded by a specified

number of "0xFF" characters and they are called the preamble. The number of preamble

can’t be less than 5 and more than 20.

3.3.2 Delimiter

This data can indicate the frame is long or short frame and the frame is master frame, slave

frame or burst frame.

3.3.3 Address

If the HART frame is short frame, the address field is only one byte. If it is long frame, the

address field is 5 bytes and include manufacturer ID, device type and device ID.

3.3.4 Command

The HART command set includes three classes shown as below.

(1) Universal Command

(2) Common-Practice Command

(3) Device-Specific Command

3.3.5 Byte Count

It is the number of bytes between it and the check byte the end of the HART frame.

3.3.6 Response Codes

It includes two bytes of status. These bytes convey three types of information:

Communication errors, Command response problems and Field device status. They are

shown as below.

[ First Byte ]

bit 7: 1 (communication error)

bit 6: Parity error

bit 5: Overrun error

bit 4: Framing error

bit 3: Checksum error

[ Note ]

(1) MB=Modbus, CMD=Command, MOD=Module, DEV=Device

(2) 500L: The low byte of MB_Addr 500.

500H: The high byte of MB_Addr 500

(3) Default CMD(num)(format):

[1] Num: means HART command number. When add a new HART device in module, these

two default commands – “Default CMD(0)” and “Default CMD(3)” will be produced

automatically.

[2] Format: means the format of HART command of HRT-7(3)10.

<1> Normal format (N): Use the standard HART command format.

<2> Simple format (S): Refer to “Appendix B: Command Format”.

(4) The description of the “Default CMD(0 & 3)” status:

It consists of two bytes. The first byte is the state of “Default CMD(0)” and the second byte is

the state of “Default CMD(3)”.

Ex: If the value is 0x0100 for the MB address 1000, then the 1000L is 0x00 and the 1000H is

0x01. It means the error status of “Default CMD(0)” is 0x00 and the error status of “Default

CMD(3)” is 0x01 in “Module 0”.

(5) The description of the User CMD status:

The maximum number of “User CMD” is 100 (0~99). The MB address range for the error

status of these User CMD is 1050~1099. It means that one MB address represents two User

CMD states.

Ex: If the value is 0x0200 for the MB address 1050, then the 1050L is 0x00 and the 1050H is

0x02. It means the error status of “User CMD Index 0” is 0x00 and the error status of “User

CMD Index 1” is 0x02.

(6) Module state machine:

0 — IDLE.

1 — Waits to send HART command.

2 — It is sending HART command.

3 — Waits to receive HART data.

4 — It is reading HART data.

(7) Module error status:

0 — No error

1 — Means the command has never be executed

2 — Receive timeout, can’t receive any HART data

3 — Receive HART data is too short

4 — The delimiter of HART data has some error

5 — The address (the bit of master type) of HART data has some error

6 — The address (the bit of burst mode) of HART data has some error

7 — The command of HART data has some error

8 — The parity of HART data has error.

9 — The communication with HART slave device has some error and The error messages

are recorded in the responses codes.

(8) Module error command index:

The index value indicates the latest error user command number. If the value is 255, it means

no any error command happened.

(9) Module error record:

When the HART comm. error happened, HRT-7(3)10 will record the error information and it

provides 3 records. The format of the error record is as below:

Byte 0: The length of send data (1 Byte)

Byte 1~53: The record of send data (Max. 53 Bytes)

Byte 54: The length of receive data (1 Byte)

HR

T-710 / HRT-310 User Manual Version 1.31 Page：

35

Byte 55~109: The record of receive data (Max. 55 Bytes)

Byte 110~113: The time stamp record (4 Bytes)

Byte 114~115: Reserved (2 Bytes)

(10) Module status reset function:

When set the value is bigger than zero, the module will clear “module request count”, “module

response count”, “module error count”, “module error status” and set “module error command

index” to 255.

(11) Auto Polling function:

When set the value to be 1, the module will execute all HART polling commands

automatically.

(12) Output Trigger function:

If change the value, the module will refer to the index value (0~99, 255 is for through mode) of

trigger command to execute the corresponding user command.

Ex: If the index of trigger command is 0 and the output trigger function value is 1, when

change the value of output trigger function from 1 to 2, the module will execute the user

command (index = 0).

(13) Default CMD(3)(S) Data: (FW_v1.5)

By using the address, users do not need to add the simple format of User CMD(3). Just do

the below setting, then HMI or SCADA can get the HART Cmd(3) data easily.

[1] Set "Default CMD(3) mode" to "Polling".

[2] Set "Swap mode" to "W&B".

[3] Run "Save to Device" function.

4.4 Through Mode

In this mode, users can send and receive the HART command directly. Please refer to the below

steps.

Step 1: Set the “Channel” to 0. (Through Mode just support channel 0)

[MB:1900L]

Step 2: Set the “Send length”. [MB:1901]

Step 3: Set the “HART command data”. [MB: 1902~2043]

Ex: 0xFF 0xFF 0xFF 0xFF 0xFF 0x02 0x80 0x00 0x00 0x82

Step 4: Set the “Auto Polling” to 0. [MB:501L]

(In this mode, “Auto Polling” function can’t be enabled.)

Step 5: Set the “The index of trigger command” to 255. [MB:502H]

Step 6: Get the receive count from “Receive count in through mode” [MB:1150H] and error count

from “Error count in through mode” [MB:1151L].

Step 7: Change the “Output Trigger function” value. [MB:502L]

Step 8: Get the value of “Receive count in through mode” and “Error count in through mode” until

one of them is different than the last value.

Step 9: If the “Receive count in through mode” is different than the last value, the user can get

the receive length from “Receive length in through mode” and the user can get receive

data from “Receive data in through mode” [MB:1153 ~ ] according to receive data length.

[MB:1152]

If the “Error count in through mode” is different than the last value, it means it can’t

receive any data.

[ Resolve ]

1. Please check the wiring between HRT-7(3)10 and HART devices and the configuration of HRT-7(3)10.

2. If the problem still exists, please connect to only one HART device. Then set the configuration of HRT-7(3)10 again and reboot module to test it again.

Flash once per half second:

[ Reason ]

HRT-7(3)10 has received the burst frame from HART device.

[ Resolve ]

In burst mode, the HRT-710 must work at the “Point to Point” network and disable the “auto polling” function.

3

The 'ERR' LED always

flashes.

[ Reason ]

It means some errors happened in the user CMD.

[ Resolve ]

Users can get the error status by using the “Device Diagnostic” function of HG_Tool.
