Safety instructions
Contents of this chapter
The chapter describes the warning symbols used in this manual and refers to the
safety instructions which you must obey when you install or connect an option module.
If you ignore the safety instructions, injury, death or damage can occur. Read this
chapter before you start the installation.
Use of warnings and notes
Warnings tell you about conditions which can cause injury or death, or damage to the
equipment. They also tell you how to prevent the danger. Notes draw attention to a
particular condition or fact, or give information on a subject.
The manual uses these warning symbols:
WARNING!
Electricity warning tells about hazards from electricity which can cause injury
or death, or damage to the equipment.
WARNING!
General warning tells about conditions other than those caused by electricity,
which can cause injury or death, or damage to the equipment.
Safety in installation and maintenance
These instructions are for all who install or connect an optional module to a drive,
converter or inverter and need to open its front cover or door to do the work.
1
Safety instructions 9

WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or
death, or damage to the equipment can occur. If you are not a qualified
electrical professional, do not do installation, commissioning or
maintenance work.
• If you are not a qualified electrician, do not do installation or maintenance work.
• Disconnect the drive, converter or inverter from all possible power sources. After
you have disconnected the drive, converter or inverter, always wait for 5 minutes
to let the intermediate circuit capacitors discharge before you continue.
• Disconnect all dangerous voltages connected to other control signal connectors
in reach. For example, it is possible that 230 V AC is connected from outside to a
relay output of the drive, converter or inverter.
• Always use a multimeter to make sure that there are no parts under voltage in
reach. The impedance of the multimeter must be at least 1 Mohm.

Introduction to the manual
Contents of this chapter
This chapter introduces this manual.
Purpose of the manual
The manual provides information on installing, commissioning and using the FMBT-21
Modbus/TCP adapter module.
Applicability
This manual applies to the FMBT-21 Modbus/TCP Ethernet adapter module, revision
E or software version 2.00 and later.
Compatibilty
The FMBT-21 Modbus/TCP adapter module is compatible with different ABB drives
and wind turbine converters.
Note: Later in this manual, the term drive is used to refer to converters as well.
￭Drives
The FMBT-21 adapter module is compatible with:
• ACS880 primary control program version 2.51.0.0 and later
• ACS580 standard control program version 2.02.0.1 and later
• ACH580 HVAC control program 2.01.0.4 and later
• ACQ580 pump control program 2.03.0.3 and later
• ACS380 machinery control program version 2.02.0.1 and later
2
Introduction to the manual 11

• ACS480 standard control program 2.02.0.3 and later
• ACS355 drive firmware version 5.090 and later
• ACH480 HVAC control program 2.06.0.2 and later
• ACS560 standard control program 2.08.0.0 and later
Note: Not all compatible firmwares are listed here. For details of compatibility, check
the drive's firmware manual. You can check the current firmware version of the drive
with parameter 07.05 Firmware version.
￭Protocols
The FMBT-21 adapter module is compatible with Ethernet standards IEEE 802.3 and
IEEE 802.3u.
The FMBT-21 adapter module supports these protocols from SW version 1.00 onwards:
• Modbus/TCP
• Modbus over UDP
In addition to these protocol, it is possible to have the no communication protocol
running on the FMBT-21 adapter module. This configuration is called NONE protocol.
In this setup, the FMBT-21 adapter module is used only for running Ethernet services
which can be enabled/disabled via parameter 51.15 Service configuration.
This table specifies the clients/masters that are compatible with the Modbus/TCP
protocol.
Compatible client/masterProtocol
All Modbus/TCP clients that support:Modbus/TCP
• Modbus Application Protocol Specification v1.1b
• Modbus Messaging on TCP/IP Implementation Guide v1.0b
￭Tools
The FMBT-21 adapter module can be used in the Ethernet tool network. The Ethernet
tool network enables commissioning and monitoring several single drives, or inverter
and supply units of a multi-drive from a single location by using the Drive composer
pro PC tool.
Note: When the FMBT-21 adapter module is used only in the Ethernet tool network,
the recommended setting for parameters 50.21 FBA A timelevel sel and 50.51 FBA B
timelevel sel is Slow or Monitoring.
12 Introduction to the manual

For more information on the Ethernet tool network, see:
•Ethernet tool network for ACS880 drives application guide (3AUA0000125635
[English])

Cybersecurity disclaimer
This product can be connected to and communicate information and data via a network
interface. The HTTP protocol, which is used between the commissioning tool (Drive
Composer) and the product, is an unsecured protocol. For independent and continuous
operation of product such connection via network to commissioning tool is not
necessary. However it is Customer's sole responsibility to provide and continuously
ensure a secure connection between the product and Customer network or any other
network (as the case may be). Customer shall establish and maintain any appropriate
measures (such as but not limited to the installation of firewalls, prevention of physical
access, application of authentication measures, encryption of data, installation 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,
intrusion, leakage and/or theft of data or information.
Notwithstanding any other provision to the contrary and regardless of whether the
contract is terminated or not, ABB and its affiliates are under no circumstances liable
for damages and/or losses related to such security breaches, any unauthorized access,
interference, intrusion, leakage and/or theft of data or information.

Overview of the Ethernet network and
the FMBT-21 module
Contents of this chapter
This chapter contains a short description of the Ethernet network and the topology
supported by the FMBT-21 adapter module.
Ethernet network
Ethernet standards support a variety of physical media (coaxial cable, twisted pair,
fiber optics) and topologies (bus and star).
The FMBT-21 module supports twisted pair as the physical media in a star topology.
The maximum length for an Ethernet segment on twisted pair media is 100 meters.
All twisted pair media between the Ethernet node and the switch or router must be
shorter than 100 meters, including media within patch panels.
￭Example topology of the Ethernet link
The figures below show example topologies for an Ethernet network with FMBT-21.

FMBT-21 module overview
The FMBT-21 Modbus/TCP adapter module is an optional device for ABB drives which
enables the connection of the drive to an Ethernet network.
Through the adapter module you can:
• give control commands to the drive (for example, Start, Stop, Run enable)
• feed a motor speed or torque reference to the drive
• give a process actual value or a process reference to the PID controller of the drive
18 Overview of the Ethernet network and the FMBT-21 module

• read status information and actual values from the drive
• reset a drive fault
• read/write parameters of the drive
• connect Drive composer pro tool.
The protocol used to access these functionalities over Ethernet is described in chapter
Modbus/TCP – Communication protocol.
The adapter module supports 10 Mbit/s and 100 Mbit/s data transfer rates and
automatically detects the data transfer rate used in the network.
The adapter module is installed into an option slot on the drive control unit. See the
drive manuals for module placement options.
