DXMR90-4K IO-Link Master

1 IO-Link Overview
IO-Link is an open standard serial communication protocol that allows for the bi-directional exchange of data from IO-Link-
supported devices, such as sensors, that are connected through IO-Link.
Advantages to an IO-Link system include standardized wiring, remote configuration, simple device replacement, advanced
diagnostics, and increased data availability. Because IO-Link is an open standard, the devices can be integrated in almost
any fieldbus or automation system.
An IO-Link system consists of an IO-Link master and an IO-Link device such as a sensor, lighting product, IO-Link hub, or
actuator.
The functions and parameters of the IO-Link devices are represented in a device description file (IODD). IODD files contain
information about identification, device parameters, process and diagnostic data, communication properties, and other
details. The IODD files for Banner IO-link devices can be downloaded for free on www.bannerengineering.com.
1.1 IO-Link Systems
At least one IO-Link master and one IO-Link device are required for IO-Link communication.
The IO-Link master and IO-Link device are connected using a 3-wire standard unshielded cable. The IO-Link master
establishes the connection between IO-Link device and the higher-level control system. An IO-Link master can have several
IO-Link ports, and only one IO-Link device can be connected to each port.
IO-Link hubs such as Banner's R90C-4B21-KQ or IO-link converters make it possible to integrate devices without an IO-Link
output in automation systems via IO-Link.
Figure 1. IO-Link map
1.2 Operating Modes
The operating mode can be configured for any port on the IO-Link master. The following modes can be used:
Deactivated
Use deactivated mode for any unused IO-link master ports if a device is not connected.

IO-Link Manual
The IO-Link master only connects IO-Link devices that have a certain vendor ID and device ID (1: IOL_MANUAL).
This mode is also required to for the Backup and Restore or Restore function.
IO-Link Autostart
The IO-Link master connects to every connected IO-Link device (2: IOL_AUTOSTART).
Digital Input
The IO-Link port functions as a standard digital input (3: DI_C/Q).
Digital Output
The IO-Link port functions as a standard digital output (4: DO_C/Q).
1.3 Combining IO-Link Devices with Different Specifications
Any combination of masters and devices is possible. However, if IO-Link devices of a different IO-Link specification are
combined, note that:
• Only IO-Link v1.0 devices can be operated on the IO-Link v1.0 masters
• IO-Link v1.0 and v1.1 devices can be operated on the IO-Link v1.1 masters
IO-Link devices with IO-Link specification V1.0 do not support backup and restore features (data storage).

2 DXMR90-4K Overview
Banner's DXMR90-4K IO-Link Master consolidates data from multiple sources to provide local data processing as well as
accessibility for host systems as a platform for the Industrial Internet of Things (IIoT).
The DXMR90-4K IO-Link Master can have multiple configurations. The DXMR90-4K will have a model number label on the
housing. Use the model number to identify which boards are included in the controller.
The DXMR90-4K contains four IO-link ports, allowing for concurrent communication to up to four IO-Link devices. Data is
collected into the internal logic controller to facilitate edge processing, protocol conversion to Industrial Ethernet, Modbus/
TCP, and pushing information to web servers. In addition to IO-Link devices, the IO-Link master can be used to transmit up
to eight discrete signals using pin 2 or pin 4 of the IO-link master ports.
The configurable IO-link master works with IO-link devices and allows for quick deployment of IO-link data to Ethernet/IP and
Modbus TCP, and Modbus RTU networks.
• Local control or connectivity with:
◦ Automation protocols including EtherNet/IP, Modbus/TCP, and Modbus RTU
◦ Internet protocols including RESTful API and MQTT with web services from AWS
• Logic processing and problem solving capable of deploying solutions to process and control data from multiple
devices
• Compact housing saves space and weight compared to traditional "block" style form factors
• IP67 housing simplifies installation in any location by eliminating the need for a control cabinet
• Consolidate cable runs to minimize cabling and associated weight, especially in weight critical applications such as
robotics
• Flexible and Customizable—Expanded internal logic controller with action rules and ScriptBasic programming

2.2 Automation Procotols
The DXMR90-4K IO-Link Master supports the following automation protocols.
EtherNet/IP
By default, EtherNet/IP is enabled. Configure the DXMR90-4K Local Registers as EtherNet/IP input or output
registers using the DXM Configuration Software. A single register can only be set as either an EtherNet/IP input or
output register.
EtherNet/IP registers are limited to 228 read registers set as E/IP Originator to DXM and 228 write registers set as
DXM to Originator
Modbus RTU
Modbus RTU port (port 0) is used by a host system to access the DXMR90-4K as a slave device. The slave Modbus
RTU port allows access all the internal local registers concurrently with the master RTU port. Port 0 can be
configured as a Modbus Master Port using the DXM Configuration Software but is defined as a slave port by default.
Configure to a Master port using the DXM Cofiguration Software to allow for data access to other Modbus devices
like the 4-Port IO-Link to Modbus Master R90C-4K-MQ or other Modbus accessible slave devices.

Modbus TCP/IP
A host system acting as a Modbus master (Client) can access the DXMR90-4K using the Modbus TCP/IP protocol
over Ethernet. Standard Modbus TCP port 502 is used by the DXMR90-4K for all Modbus TCP/IP requests.
All internal local registers are available to the host system concurrently with Modbus TCP.
By default, the DXMR90-4K is configured as a Modbus TCP/IP Server.

XML Config File
The configuration software creates an XML file that is transferred to the DXM using an Ethernet connection. The DXM can
also receive the XML configuration file from a Web server using an Ethernet connection. This configuration file governs all
aspects of the DXM operation. The DXM Configuration Software allows the user to define parameters for the DXMR90-4K,
then saves the configuration in an XML file on the PC.
After the configuration file is saved, upload the XML configuration file to the DXMR90-4K for operation.
Important: The DXMR90-4K IO-Link Master comes preloaded with a default configuration XML file. You
can download the default XML on the product page for the DXMR90-4K.
This quick start guide outlines the basic operations to set up a DXMR90-4K using the configuration software. For a more
comprehensive explanation of features, refer to the DXM Configuration Software Instruction Manual (p/n 209933).

3.2.2 Configuring the DXMR90-4K Controller
This section will walk you through the method of setting up the DXM Configuration Software and communicating with a
connected DXM device. Version 4 of the DXM Configuration Software supports multiple DXM device models, each of which
incorporates different features.
As soon as a DXM model is connected to your computer, the software automatically detects the correct model and loads the
appropriate screens. You may also manually select which model of DXM you are configuring if you intend to create a
configuration file without connecting a device. This ensures that the interface and the configuration file use the correct
features.
Not all screens are available for all models. To change to another model of DXM, go to the Select Mode screen and use the
drop-down list to select another model. If the active configuration is incompatible with the selected model, you will be
prompted to either proceed and wipe out the active configuration or cancel the model change and preserve the configuration.
Figure 5. Opening splash screen for Traditional Setup mode
When the Select DXM Model drop-down is set to DXMR90-4K, a new network discovery table is displayed. Click Scan
Network for DXMs to detect DXM devices on the host computer's network. Discovered DXMs are listed in the network
discovery table. Double-click any row entry to connect to that DXM. If the DXM's IP address is already known, the standard
TCP connection option is available below the network discovery table.
The default IP address of the DXMR90-4K is 192.168.0.1. To connect to the device, you need to be on the same subnet. You
can do this by accessing the control panel on your PC and accessing your Network Connections properties. It is important to
ensure that the adaptor you are connected to is within the 192.168.0.* subnet when you first connect to the DXMR90-4K IO-
link master.

Figure 6. Windows Network Properties settings screen
Important: Any model of DXM may connect to the configuration software regardless of which device model
is selected in the configuration software. Compatibility is checked before configuration files are uploaded to
the device.
For more information on the device registers and port settings of the DXMR90-4K IO-Link Master, refer to the DXMR90-4K
IO-Link Master Device Register Map (p/n 229732).
Modify Multiple Registers
Modify a range of registers from the Local Registers > Local Registers in Use > Modify Multiple Registers screen.
Select which parameter fields to modify. Most parameters have three selections.
• Unchanged—no changes
• Default—change to default settings
• Set—modify parameter. Other selections will appear based on the parameter.
Figure 7. Modify Multiple Registers screen
1. Enter the Starting register and Ending register.
2. Select the value to change using the drop-down list next to each value.
3. Enter the new value in the field provided.
4. To push register values to the web server, set Cloud Permissions to read.
DXMR90-4K IO-Link Master
www.bannerengineering.com - Tel: + 1 888 373 6767 11

If the Cloud Permissions are set to Read, the web server only views data from the device and cannot write data to
the device. If the permissions are set to Write, the web server only writes to the device and cannot read the data. If
the permissions are set to Read/Write, the web server can read the data from the device and write to the device from
the web.
5. Click Modify Registers to apply the changes.
Set the IP Address
Follow these instructions to change the DXMR90-4K's IP address.
By default, the DXMR90-4K is set to a static IP address of 192.168.0.1. The IP address can be changed by using the DXM
Configuration Software and updating the XML.
1. Launch the DXM Configuration Software.
2. Go to the Settings > Ethernet screen.
3. In the IP Address section, select Static IP or DHCP from the drop-down list.
• If Static IP is selected, enter the IP address, Subnet, and Gateway address as desired.
• If DHCP is selected, the IP address, Subnet, and Gateway address are grayed out and not configurable.
Changing the IP Address to DHCP can make it so the DXM cannot be reached. Before changing this to DHCP,
you MUST have a server that is going to assign an IP Address to the DXMR90-4K.
4. Save your changes to the configuration file (File > Save).
5. Upload the configuration file to your controller (DXM > Send Configuration to DXM).
Save and Upload the Configuration File
After making any changes to the configuration, you must save the configuration files to your computer, then upload it to the
device.
Changes to the XML file are not automatically saved. Save your configuration file before exiting the tool and before sending
the XML file to the device to avoid losing data. If you select DXM > Send XML Configuration to DXM before saving the
configuration file, the software will prompt you to choose between saving the file or continuing without saving the file.
1. Save the XML configuration file to your hard drive by going to the File > Save As menu.
2. Go to the DXM > Send XML Configuration to DXM menu.
Figure 8. Status indicator bar
• If the Application Status indicator is red, close and restart the DXM Configuration Tool, unplug and re-plug in the
cable and reconnect the DXM to the software.
• If the Application Status indicator is green, the file upload is complete.
• If the Application Status indicator is gray and the green status bar is in motion, the file transfer is in progress.
After the file transfer is complete, the device reboots and begins running the new configuration.
3.3 Mechanical Installation
Install the DXMR90-4K to allow access for functional checks, maintenance, and service or replacement.
All mounting hardware is supplied by the user. Fasteners must be of sufficient strength to guard against breakage. Use of
permanent fasteners or locking hardware is recommended to prevent the loosening or displacement of the device. The

For more information on the device registers and port settings of the DXMR90-4K IO-Link Master, refer to the DXMR90-4K
IO-Link Master Device Register Map (p/n 229732).
4.1 Ethernet
Before applying power to the DXMR90-4K, verify the Ethernet cable is connected.
The Ethernet connection supports the DXM Configuration Software, Modbus/TCP, and EtherNet/IP. ScriptBasic also has
access to Ethernet for custom programming. Use the software to configure the characteristics of the Ethernet connection,
including the IP address. Any parameters not changeable from the menu system are configurable from the configuration
software.
4.2 Internal Local Registers (Slave ID 199)
The main storage elements for the DXMR90-4K are its Local Registers, which can store 4-byte values that result from
register mapping, action rules or ScriptBasic commands.
For more information on the device registers and port settings of the DXMR90-4K IO-Link Master, refer to the DXMR90-4K
IO-Link Master Device Register Map (p/n 229732).

Local Registers updated from Modbus and Ethernet/IP transactions are restricted to a16-bit data value to follow standard
Modbus Holding Register definition.
The Local Registers defined in Action Rules must all be within the same register group. For example, an Action Rule cannot
have inputs from an integer group with the result register defined as a floating point register. To move between integers and
floats, use the Register Copy Rule.
Registers Description
12001-12845, 17001-19000 32-bit unsigned integer-based registers
12846-12850 Special function registers (can be reset registers)
12851-12900, 19001-20000 Non-volatile register with limited capability for permanent data storage
13001-17000 32-bit IEEE 754 floating point registers. Floating point values require two Local Registers to store a value.
Floating point Local Registers are referenced on the odd numbered register addresses: 13001, 13003, and
13005. When using Action Rules/Read Rules, always reference the odd numbered register addresses.
Local Registers 12001–12845, and 17001–19000 (Internal Processor Memory, 32-bit, Unsigned)—The Local Registers are
the main global pool of registers. Local Registers are used as basic storage registers and as the common data exchange
mechanism. External Modbus device registers can be read into the Local Registers or written from the Local Registers. The
DXMR90-4K, as a Modbus master device or a Modbus slave device, exchanges data using the Local Registers. Modbus
over Ethernet (Modbus/TCP) uses the Local Registers as the accessible register data.
Local Registers 12846–12850 (Reset, Unsigned)—These Local registers are reserved for use as Reset registers. A time
interval can be specified in the configuration software for the DXM to reset. If the data in the register does not change within
the user-specified time interval, the DXM resets.
Local Registers 12851–12900 and 19001–20000 (Data Flash, Non-volatile, 32-bit, Unsigned)—The top 50 Local Registers
are special non-volatile registers. The registers can store constants or calibration type data that must be maintained when
power is turned off. This register data is stored in a data flash component that has a limited write capability of 100,000 cycles,
so these registers should not be used as common memory registers that change frequently.
Local Registers 13001–17000—These Local Registers are paired together to store a 32-bit IEEE floating point format
number in big endian format. Registers 12001 [31:16], 12002 [15:0] store the first floating point value; registers 12003, 12004
store the second floating point number. There are a total of 2000 floating point values; they are addressed as two 16-bit
pieces to accommodate the Modbus protocol. Use these registers when reading/writing external devices that require Modbus
registers in floating point format. Since Modbus transactions are 16-bits, the protocol requires two registers to form a 32-bit
floating point number.
Virtual Registers—The DXMR90-4K has a small pool of virtual registers that show internal variables of the main processor.
Some register values will be dependent upon the configuration settings of the DXMR90-4K. Do not use Read Rules to move
Virtual Local Registers data into Local Registers. Use the Action Rule > Register Copy function to move Virtual Local
Registers into Local Registers space (12001–12850).

4.3 Connecting to Remote IO-Link Devices
The DXMR90-4K has four IO-link ports for connecting IO-Link devices and digital sensors, lights, and actuators. All ports use
a 4-pin M12 female connector to connect to remote devices. No additional wiring is required if the sensors use compatible
wiring.

Figure 11. RTU Configuration screen for ports 1-4
The DXM Configuration has a special tab for configuring the port settings on the IO-link master. To access go Register
Mapping--> IO-link Configuration. In this section you can configure the port settings of the IO-link Master.
The operating mode can be configured for any port on the IO-Link master. The following modes can be used:
Deactivated
Use deactivated mode for any unused IO-link master ports if a device is not connected.
IO-Link Manual
The IO-Link master only connects IO-Link devices that have a certain vendor ID and device ID (1: IOL_MANUAL).
This mode is also required to for the Backup and Restore or Restore function.
IO-Link Autostart
The IO-Link master connects to every connected IO-Link device (2: IOL_AUTOSTART).
Digital Input
The IO-Link port functions as a standard digital input (3: DI_C/Q).
Digital Output
The IO-Link port functions as a standard digital output (4: DO_C/Q).
For more information on the port settings of the DXMR90-4K IO-Link Master, refer to the DXMR90-4K IO-Link Master Device
Register Map (p/n 209933).
4.3.1 Replacing an IO-Link Device During Operation (Backup/Restore
Mode)
Replacing an IO-Link device during operation is common, and inadvertent changes to device settings can cause operational
problems and down-times. Operating personnel without special knowledge or tools can replace IO-Link devices quickly and
without errors.
When the backup function of the IO-Link master is used, the IO-Link master automatically provides the saved parameters to
the new device after replacement. This makes IO-Link device replacement seamless in IO-Link applications. Another
common industry term for this function is data storage mode.

. Backup+Restore Mode
If a port on the IO-Link master is set to Backup+Restore, then the new device added to the IO-Link port takes in the
same device configuration as the device that was just replaced, as the IO-Link master had stored the last
configuration change by a backup (3: Type compatible Device V1.1, Backup + Restore).
. Restore
If the port on the IO-Link master port is set to Restore, then the new device takes in the configuration according the
settings saved in the master at the time of the last backup. Because possible configuration changes were not saved
in the master, a different behavior from the previous one before the replacement may occur (4: Type compatible
Device V1.1, Restore).
4.4 Configuring Connected Banner IO-Link Devices
Banner's IO-Link Configuration Software offers an easy way to configure Banner IO-Link masters and Banner IO-Link
devices, offering users control of master and device configuration.
The easy-to-use software provides a variety of tools and works with the DXMR90-4K, R90C-4K-MQ, and R45C-2K-MQ IO-
Link Masters. Configure Banner IO-link Masters and IO-Link devices using the free IO-Link Configuration Software, available
for download on the product page for the DXMR90-4K at: https://www.bannerengineering.com/us/en/products/part.
813874.html.
Like the DXM Configuration Software, this software enables you to configure port settings for the DXMR90-4K. It also has the
ability to configure Banner IO-link Devices connected to the DXMR90-4K.
For instructions on how to use the software to configure IO-link port settings and IO-link devices connected to the IO-link
master, use the IO-Link Configuration Software Instruction Manual, available from the software by going to Help > Help File.
The IO-link Configuration Software Instruction manual can also be downloaded directly on the product page for the
DXMR90-4K.
4.5 Connecting to Remote Modbus Devices
In addition to the 4 IO-link ports, the DXMR90-4K has one Modbus Master Port, the female M12 port uses a 4-pin M12
female connector to connect to remote devices. No additional wiring is required if the sensors use compatible wiring.

The DXMR90-4K can be a Modbus RTU master device to other slave devices and can be a Modbus slave device to another
Modbus RTU master. The DXMR90-4K uses female port 0 as a Modbus RTU master port to control external slave devices.
All wired devices connected to the master RS-485 port must be slave devices.
• As a Modbus RTU master device, the DXMR90-4K controls external slaves connected to female M12 port 0
• As a Modbus RTU slave device, the DXMR90-4K local registers can be read from or written to by another Modbus
RTU master device via port 0.
The Modbus RTU slave connection, port 0, is controlled by another Modbus master device that is not the DXMR90-4K. The
slave port is used by an external Modbus master device that will access the DXMR90-4K as a Modbus slave Device. Use the
DXM Configuration Software to define the operational settings for both the Modbus RTU master port 0 and the Modbus RTU
slave port 0.
The basic communications parameters for the RS-485 ports are set in the DXM Configuration Software and are saved in the
XML configuration file.
4.5.1 Define an RTU Read Rule
Follow these steps to create a new read rule.
This example creates a read rule to read six registers (address 1 through 6), from Port 0 Modbus Slave 4. The results are
stored in the Local Registers 12001 through 12006.

Figure 12. System settings
1. Go to Settings > System to define the port settings to be compatible with the connected devices.
a) Verify the Baud rate and Parity match that of the connected Modbus slave devices.
b) The timeout controls how long the DXMR90 waits before determining a command has failed to send. Set the
timeout based on your specific application requirements.
c) The Delay between messages defines the minimum wait time between resending another command. Set the
delay based on your specific application requirements.
The Baud rate is defined for both the Modbus master and slave; settings include 19200 (default), 1200, 2400, 9600,
38400, 57600, and 115200. The Delay between messages applies to the Modbus master port and sets the
minimum wait time from the end of a Modbus transaction to the beginning of the next Modbus transaction. Parity is
defined for both the Modbus master and slave; settings include None (default), odd, even, space, and mark. Timeout
applies to the Modbus master port and covers the expected time for messages to be sent throughout the wireless
network. For the DXM, the Timeout parameter is the maximum amount of time the DXM should wait after a request is
sent until the response message is received from the Modbus slave device.
2. From the Register Mapping > RTU > RTU Read screen, click Add Read Rule.
3. Click the arrow next to the name to display the parameters.
4. Name your rule.
5. Select the slave ID.
6. Select how many registers to read, and the beginning register.
7. Define the register type, how often to read the register, and any other appropriate parameters.
8. If necessary, select the error condition. For this example, if the read function fails after three attempts, the read rule
writes 12345 to the DXM local registers. Notice the list of local register names this read rule is using.
