Cyber Security Legal Disclaimer
This product is designed to be connected to and to communicate information and data via a
network interface. It is your sole responsibility to provide and continuously ensure a secure
connection between the product and your network or any other network (as the case may
be). You shall establish and maintain any appropriate measures (such as but not limited to
the installation of firewalls, application of authentication measures, encryption of data, in-
stallation of anti-virus programs, etc.) to protect the product, the network, its system and
the interface against any kind of security breaches, unauthorized access, interference, intru-
sion, leakage and/or theft of data or information. ABB Ltd and its affiliates are not liable for
damages and/or losses related to such security breaches, any unauthorized access, interfer-
ence, intrusion, leakage and/or theft of data or information.
Risk Mitigation and Secure Deployment
The idea is to create defence-in-depth protection for each network by allocating firewall solu-
tions to the front of internal trusted networks of each network by manage firewalls, their
configurations and access rules. The softstarter must be positioned in a trusted network,
strictly limited and in a hosted portion of a network or control system. Configure firewalls ac-
cording to the principle of denying everything that is not needed nor used. For secure remote
access, use a VPN connection with an encryption layer to create a secure channel over an inse-
cure network. For more information regarding cyber security and risk mitigation, download
the document Cyber security for ABB drives from the ABB library.
Information
The device uses the default Modbus TCP port 502 (0x01F6). This port must be
open in the firewall for both incoming and outgoi
ng traffic to allow Modbus-TCP
compatible devices to communicate.

1. Overview
This document aims to describe the installation and configuration process of the MTQ22-FBP
Modbus TCP adapter module. Modbus is a master-slave protocol and only one device can
transmit on the line at any time. The master (which in most cases is a PLC) manages the ex-
changes and only it can take the initiative. It interrogates each of the slaves in succession and
no slave can send a message unless it is invited to do so. The master repeats the question
when there is an incorrect exchange, and declares the interrogated slave absent if no re-
sponse is received within a given time period. If a slave does not understand a message, it
sends an exception response to the master who may or may not repeat the request.
The adapter will be used to enable Modbus TCP communication between an ABB PSE
softstarter and a Modbus master over an IP network. The TCP Modbus communication proto-
col differs from the other Modbus versions through the use of TCP/IP communication as a
wrapper for the Modbus data. Modbus RTU messages are sent over an IP network. The use of
IP datagrams removes the need for slave addresses since all slaves use a unique IP address to
enable IP communication. However, The MTQ22-FBP still uses Modbus RTU to communicate
with the PSE which require the slave ID to match between the MTQ22-FBP and the PSE, as ex-
plained in section 3.2.
The document starts with technical information regarding the required devices and a de-
scription of how to connect them to enable Modbus TCP communication. The third chapter
explains how to configure the PSE and MTQ22-FBP software, Fieldbus Control, Slave address,
IP address and other important parameters are configured with detailed instructions. The
fourth chapter presents the MTQ22-FBP data registers, used to read or write data to the con-
nected PSE devices. In case of any TCP Modbus connection problems, chapter 5 explains the
meaning of the MTQ22-FBP diagnostic LED indicators. This manual is written specifically for
Modbus TCP and will not cover other fieldbus protocols or other devices then ABB Softstart-
ers type PSE18…PSE370. For more detailed information regarding warranty, service, type des-
ignation and other product specific information for the associated devices, see respective
manual.

2. Technical Description
The following list highlights the core features and functionalities provided by the MTQ22-FBP
and Modbus TCP protocol.
Highlighted Features
–The MTQ22-FBP Ethernet adapter module provides Ethernet connectivity for the ABB PSE
softstarter Fieldbus plug (FBP) device.
–Up to four FBP devices can be connected to one MTQ22-FBP. This allows a very cost-effi-
cient connection of FBP devices to Ethernet.
–Through the MTQ22-FBP Ethernet Adapter module it is possible to:
•Give control commands to the device (Start, Stop, Set Auto Mode, etc.)
•Read status information and actual values from the device
•Read maintenance counters
•Reset a trip
–A built in two-port switch allows the flexible usage in bus, star or ring network topologies.
–Up to four masters can concurrently access the connected devices.
–Access via Modbus TCP can be restricted to a limited set of IP addresses.
–The Media Redundancy Protocol (MRP) is implemented (client). MRP is standardized in
IEC/EN 62439-2 and offers cable redundancy in case of a single failure.
2.1. Modbus TCP
Modbus TCP is a variant of the Modbus family of simple, vendor neutral communication pro-
tocols intended for supervision and control of automation equipment. Specifically, it covers
the use of Modbus messaging over TCP connections on an IP network.
The implementation of the Modbus TCP server in the MTQ22-FBP module is done according
to:
–Modbus Application Protocol Specification v1.1b
–Modbus Messaging on TCP/IP Implementation Guide v1.0b
The supported Modbus commands can be found in chapter 4. Further information on the
Modbus TCP protocol is available at www.modbus.org.

2.2. MTQ22-FBP
A device layout of the MTQ22-FBP can be seen in Figure 1. Connectors X1 ... X4 are used to
connect up to four FBP devices to the MTQ22-FBP. On the left side of the port connectors
LEDs show the current communication status. See chapter 5 for detailed information regard-
ing status LEDs.
Figure 1: Top view of the MTQ22-FBP. Four PSE devices can be connected to the MTQ22 via the
ports X1 to X4. The standard Micro USB connector X5 allows to configure the device.
The Micro USB connector X5 allows device configuration using a PC, see chapter MTQ22-FBP.
Two RJ45 sockets E1 and E2 offer Ethernet connectivity. The communication status of each
interface is shown by two LEDs. The MTQ22-FBP must be supplied with 24VDC via X6.
Mounting and Dismounting
You can mount and dismount the MTQ22-FBP onto a 35 mm standard mounting rail, without
tools.
Arrange the communication cables as far away from the motor cables as possible. Avoid par-
allel runs. Use bushings at cable entries. The network cable is connected to the RJ45 connect-
ors on the MTQ22-FBP module. Standard CAT5 UTP, FTP or STP cables can be used. The shield
of the RJ45 cable is connected to the shield of connector X6.

2.3. Connection Setup
In order for Modbus to function properly the PSE must be connected point-to-point with a
Fieldbus Plug Accessory (PS-FBPA) as seen in Figure 2. Further the PS-FBPA must be con-
nected to one of the ports named X1 to X4 on the MTQ22-FBP. The Modbus master is in turn
connected to one of the Ethernet connections E1 or E2.
Figure 2: Device connections required to enable a Modbus TCP connection between the PSE
and a Modbus master.
The cable connecting the PS-FBPA and the MTQ22-FBP, a CDP19-FBP .100 cable must be pur-
chased separately. A spring terminal block connector must also be installed on the separate
cable and connected according to Figure 3.

3. Software Configuration
This chapter describes how to configure the MTQ22-FBP and the PSE to enable Modbus com-
munication.
3.1. PSE Softstarter
The following list of instructions explains how to configure the fieldbus parameters on the
PSE softstarter.
1. Fieldbus Control
This parameter is used for configuration of the fieldbus communication. Connecting the PSE
Softstarter to the Fieldbus plug automatically enables fieldbus communication. To enable
control of the softstarter using fieldbus, this parameter must be set to On. If Fieldbus Con-
trol is set to OFF, fieldbus can only be used for monitoring softstarter data.
I
f this parameter is set to On, the softstarter
might trip on fieldbus fault if no fieldbus com-
munication is available. If the intention is to
run without fieldbus control, this parameter
should be set to OFF.
2. Fieldbus Address
The parameter Fieldbus Address allows setting of address for the fieldbus communication.
The setting range for the fieldbus address is 0...255. If the address is set to 255, the address
stored in internal memory of the fieldbus plug will be used.
It is possible to read and set this parameter via the keypad when Fieldbus Control is set to On
or OFF.
Changing this parameter will automatically re-
set the fieldbus interface and the new address
will be active. If MTQ22
-FBP was communi-
cating with the old address, the MTQ22
-FBP
needs to
be re-configured and the PSE re-
started.

The fieldbus type parameter must be set to FbP (fieldbus plug) when using the MTQ22-FBP.
FbP is the default value of the parameter. The PSE has a built-in version of Modbus which is
activated by setting the parameter to Int (Internal).
–
When FbP is selected – configured to use
external fieldbus plug, such as the MTQ22-
FBP.
–
When Init is selected – PSE will use the in-
ternal Modbus implementation to com-
municate with external devices.

5. Fieldbus Operation When Fault
This parameter is accessible only if Fieldbus Control is previously set to On.
In case of fieldbus malfunction, for instance due to power loss or a broken cable, this param-
eter allows for different (operations in case of a fault) reactions to the fault.
Setting Fieldbus fault reaction to trIP will make the softstarter trip on a fieldbus fault. Select-
ing trIP makes reset of the fault necessary, in case of a tripping event.
When
LocC is selected, the control of the
softstarter will automatically switch from
fieldbus control to local control. The switch to
local control will make hard
-wire control possi-
ble. When the Fieldbus starts working again
the control is automatically switche
d back to
the Fieldbus. There is a 10 second delay before
it is possible to controlling the motor.
Default value

6. Type of Operation for Reset of Fieldbus Fault
Select what operation shall be asserted if a fieldbus communication fault occurs. Manual or
automatic options are available. HAnd is the default value for reset of Fieldbus Fault:
–
If HAnd is selected - The motor will
stop and
manual reset is required.
–
If Auto is selected - The motor will stop and
automatic reset is performed.
This parameter is accessible only if trIP
is previ-
ously selected for the parameter fieldbus Oper-
ation When Fault.

3.2. MTQ22-FBP
An easy to use PC configuration tool is provided to adjust the parameters of the MTQ22-FBP.
The PC can be connected to the MTQ22-FBP with a standard Micro USB-cable. The ABB Con-
figuration Tool can be downloaded by clicking the following link or searching for
1SAJ260900R0001 at the ABB Download Center.
Figure 4: Connecting the MTQ22-FBP to a service Laptop. The MTQ22-FBP must be supplied
with 24V DC before the configuration can take place (1). For the connection a Micro USB cable
(2) is used. On the PC the MTQ22-FBP configuration software must be installed (3).
If the MTQ22-FBP is connected for the first time the required USB driver has to be installed.
The Microsoft USB driver is not part of the software package because of license reasons. It is
pre-installed on Windows 7 and 10, for XP it must be downloaded separately from Microsoft.
Follow the setup instructions of Windows to install the new software. After startup of the ap-
plication the screen is split into three areas - left, middle and right. In the left area you can
add as many MTQs as you have in your project. In the middle area the configuration parame-
ters per MTQ22-FBP are displayed. You can change them offline or online. The right area
shows a short help text.
Make sure to start the Configuration Tool as administrator and to connect the USB cable be-
tween the PC and MTQ22-FBP before the program is started.

4. Modbus TCP Register Map
The following chapter shows how to generally access data of the FBP-devices connected to
port one to port four of the MTQ22-FBP.
I
nformation
Modbus TCP counts registers beginning with one. But on the bus registers start
counting from zero. The addresses in this manual describe the addresses that ar
e
transmitted on the network. Depending on your client application it might be nec-
essary to increment all addresses by one.
The I/O-data as well as diagnostic and configuration data of the connected PSE devices can
be accessed applying the supported Modbus function codes. The supported functions can be
found in respective sub section.
4.1. Digital Input Telegram
To read the digital input telegram, use Modbus function code 1

4.4. Parameters
The MTQ22-FBP does not support reading or writing PSE softstarter parameters such as
start ramp time, initial voltage and torque control.
4.5. Diagnostics
To read the diagnostics data, use Modbus function code 3
Read Holding Registers or 4 Read Input Registers. The following chapter presents register
values associated to diagnostic data for both PSE and MTQ-FBP devices.

4.5.1. MTQ22-FBP
The status of the connected FBP devices can be read via Modbus TCP on the addresses 0x80
to 0x83 for the devices connected to port 1 ... port 4.

4.5.2. PSE Softstarter
PSE softstarter diagnostics are represented by bits in a 16-unsigned integer register. Use a
calculator to translate the decimal number to one or more bits. If a bit is set that fault is ac-
tive and could potentially be resetted.
