Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will be
used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property
damage.

Wiring up 3
3.1 Connection and block diagram
The AQ 4xI HART HA analog module can be used with all BaseUnits of the type A0 or A1.
You connect the final controlling elements to the BaseUnit of the analog module. The infeed of
the supply voltage on the light BaseUnit of the associated potential group supplies the module
and the final controlling elements.
A new potential group always begins with a light BaseUnit.
BaseUnit
The BaseUnit is not included in the product package of the module and must be ordered
separately.
You can find an overview of the BaseUnits that you can use with the analog module in Product
information for documentation of the ET 200SP Distributed I/O System (http://
support.automation.siemens.com/WW/view/en/73021864)
You can find information regarding selection of the suitable BaseUnit in system manual ET
200SP distributed I/O system (http://support.automation.siemens.com/WW/view/en/
58649293) and in the equipment manual ET 200SP BaseUnits (http://
support.automation.siemens.com/WW/view/en/59753521).
Information regarding wiring of the BaseUnit, creating the cable shield, etc., can be found in
system manual ET 200SP distributed I/O system (http://support.automation.siemens.com/WW/
view/en/58649293) in the section "Connecting".
Note
The first BaseUnit of a station must be a light BaseUnit. Also keep this in mind during the
configuration.

HART function 4
Definition
"HART" stands for "Highway Addressable Remote Transducer". The HART protocol is a
standardized communication protocol for communication with the suitable field devices over a
bus system.
HART is a registered trademark of the HART Communication Foundation (HCF), which owns
all the rights to the HART protocol.
You can find detailed information about HART in the HART specification.
Advantages of HART
Using the AQ 4xI HART analog module provides you the following advantages:
● Connection compatibility with standard analog modules: Current loop 4 - 20 mA
● The AQ 4xI HART analog module is an interface between the S7 system and HART devices
● Communication using the HART protocol
● Communication to field devices with HART functions
Use in the system
The AQ 4xI HART analog module is used in the distributed I/O that is connected to PROFIBUS-
DP or PROFINET IO.
You can connect a HART field device to any channel:
● The AQ 4xI HART analog module operates as a HART master, monodrop;
● the HART field devices operate as HART devices.
Typical applications
The following applications are typical:
● Commissioning of field devices (centralized parameter assignment)
● Online modification of field device parameters
● Information, maintenance and diagnostic displays for the field devices
● Integration of configuration tools for field devices via the HART interface

4.1 How HART works
Introduction
The HART protocol describes the physical form of the transfer: transfer procedures, message
structure, data formats and commands.
HART signal
The figure below shows the analog signal with the modulated HART signal (FSK method),
which consists of sine waves of 1200 Hz and 2200 Hz and has a mean value of 0. It can be
filtered out using an input filter so that the original analog signal is available again.

HART communication
The AQ 4xI HART analog module processes the HART communication in multiplex mode, i.e.
one channel after the other. As a result, HART commands of the individual channels influence
the speed of the HART processing of the other channels.
When HART mode is enabled, the analog module autonomously sends HART commands to
the connected field devices. For each channel, commands are always sent time about with any
pending external HART commands that are received over the command interface of the
module, see section "HART communication interface (Page 22)".
Commissioning a HART field device
Only HART field devices that are set to the short frame address 0 can be operated.
HART function
4.1 How HART works
Analog Output Module AQ 4xI HART HF
16 Manual, 05/2019, A5E35098013-AA

If a HART field device with a different short frame address is connected or a connected field
device is reconfigured to a short frame address other than 0 during operation, the module starts
a scan of all possible short frame addresses at the next re-establishment of HART
communication (command 0 with short frame addresses 1...63).
As soon as the connected field device responds, it is converted to the short frame address 0
(HART command 6) by the module. During the scan, the module reports a HART
communication error.
HART commands
The assignable properties of the HART field devices (HART parameters) can be set with HART
commands and read by means of HART replies. The HART commands and their parameters
are divided into three groups with the following properties:
● Universal
● Common practice
● Device-specific
Universal commands must be supported by all manufacturers of HART field devices and
common practice commands should be supported. There are also device-specific commands
that apply only to the particular field device.
Examples of HART commands
The following two tables show examples of HART commands:
Table 4-1 Examples of universal commands
Command Function
0 Read manufacturer and device type - only with this command 0 can field devices be addressed by means of
a short frame address
11 Read manufacturer and device type
1 Read primary variable and unit
2 Read current output and percent of range, digitally as floating-point number (IEEE 754)
3 Read up to four pre-defined dynamic variables (primary variables, secondary variables, etc.)
9 For field devices starting from HART Rev. 7, read up to four pre-defined dynamic variables (primary variable,
secondary variable, etc.)
13, 18 Read or write tag, descriptor and date (data included in transmission)
Table 4-2 Examples of common practice commands
Command Function
36 Set upper range value
37 Set lower range value
41 Perform self-test
43 Set the primary variable to zero

Structure of the HART protocol
Each HART frame sent from the analog module to the connected field device (request frame)
and each HART frame from the field device (response frame) has the following basic structure.
Table 4-3 Structure of the HART protocol
PREAMBLE STRT ADDR COM BCNT STATUS DATA CHK
Key:
PREAMBLE: Bytes (0xFF) for synchronizing. 5 to 20 bytes depending on parameter
assignment
STRT: Start character (start delimiter) 1 byte
ADDR: Addresses of the field device 1 byte; short address or 5 bytes; long ad‐
dress
COM: HART command number 1 byte
BCNT: Byte count, number of bytes to follow without checksum 1 byte
STATUS: HART device status. Only present for a response frame.
see following tables "Structure of HART device status"
1st and 2nd status bytes
DATA: Transferred user data / parameters, quantity depending on com‐
mand
0 … 230 bytes
CHK: Checksum 1 byte
With the exception of the preamble bytes, this structure is contained in the communication data
of the HART command interface. See section HART request and response data records
(Page 60).
HART replies always contain data. Together with a HART response, the HART device status
(1st and 2nd status bytes) is sent. Always evaluate the HART device status. If no error is
pending, the HART response is correct.
