1Introduction
Leuze electronic MD 748i / MD 248i 7
This document provides installation, configuration and embedded web interface information for the Leuze
electronic Profinet IO-Link Master.
The web interface provides a platform so that you can easily configure, review diagnostic pages, and
access advanced features, such as the ability to:
 Set up user accounts with different user levels and passwords
 Load IODD files and configure IO-Link device parameters
 Implement manual or automatic data storage (upload or download)
 Implement device and/or data validation
The IO-Link Master installation includes the following procedures.
1. Connect the power and Ethernet cable.
2. MD 748I-11-42/L5-2222: If desired, set the rotary switch.
Note: Optionally, you can configure the IP address using the embedded web interface.
3. Configure PROFINET IO.
4. If necessary, upload the latest images for the latest features.
5. Connect the IO-Link and digital I/O devices.
6. Use the web interface to configure the following:
a. If desired, upload the appropriate IODD files for your IO-Link devices for IO-Link device
configuration.
b. Use the Diagnostic pages to monitor or troubleshoot your devices.

2Hardware Installation
Leuze electronic MD 748i / MD 248i 8
2 Hardware Installation
Use the following procedures to install the IO-Link Master hardware:
 Setting the Rotary Switch (IP67 Model): see chapter 2.1
 Connecting to the Network: see chapter 2.2
 Connecting the Power: see chapter 2.3
 Mounting the IO-Link Master: see chapter 2.3
Note: The MD 248i-12-8K/L4-2R2K must be installed in a suitable fire, electrical, mechanical enclosure.
2.1 Setting the Rotary Switch (IP67 Model)
You can use the rotary switches under the configuration window on the IO-Link Master to set the lower
3-digits (8 bits) of the static IP address. Optionally, you can leave the rotary switch set to the default and
use the embedded web interface to set the network address.
If the rotary switches are set to a non-default position, the upper 9-digits (24 bits) of the IP address are
then taken from the static network address. The switches only take effect during startup, but the current
position is always shown on Help | SUPPORT page.
Using the rotary switches to set the IP address may be useful in the following situations:
 A permanent method to assign IP addresses while setting machines for a special application
where a PC or laptop is not available.
 A temporary method to assign IP addresses to several IO-Link Masters so that they do not have
duplicate addresses to make setting the IP addresses using software easier. After the web page
to change the IP address, reset the rotary switches back to 000.
 An emergency method to return the IO-Link Master back to factory defaults, so that software can
be used to program the appropriate IP address, and then return the switches back to 000.
Note: If you set the network address using the rotary switches, the rotary switch setting overrides the network
settings in the web interface when the IO-Link Master is initially powered on or after cycling the power.
Switch Setting
Node Address
000
(Default setting)
Use the network configuration stored in the flash. The default network
configuration values are:
•IP address = 192.168.60.101
•Subnet mask = 255.255.255.0
•IP gateway = 0.0.0.0
After completing the hardware installation, see chapter 3 Configuring the IO-Link
Master with STEP 7 to set the network address using the web interface.
001-254
This is the last three digits in the IP address. This uses the first three numbers
from the configured static address, which defaults to 192.168.60.xxx.
Note: If software is used to change the IP address to another range before setting
the rotary switches, the IO-Link Master uses that IP address range. For
example, if the IO-Link Master is set to 10.0.0.250 and the first rotary switch
is set to 2, the IP address would be 10.0.0.200.
255-887
Reserved.
888
Reset to factory defaults. If the IO-Link Master is set to 888 and the IP address
is changed using other methods, the IP address is returned to the default IP
address if the IO-Link Master is rebooted or power cycled.
889-997
Use the network configuration values stored in the flash (reserved).

2Hardware Installation
Leuze electronic MD 748i / MD 248i 9
Switch Setting
Node Address
998
Setting the rotary switches to 998 configures the IO-Link Master to use DHCP
addressing.
999
Use the default IP address. If the IO-Link Master is set to 999 and the IP
address is changed using other methods, the IP address is returned to the
default IP address if the IO-Link Master is rebooted or power cycled.
2.1.1 MD 748i-11-42/L5-2222 - Setting the Rotary Switch
Use the following steps if you want to change the default rotary switch settings.
1. Remove the two Phillips screws securing the switch window.
2. Gently swing open the switch window from the left to the right, allowing it to pivot on the hinge on
the right side.
3. Turn each dial to the appropriate position using a small flathead screwdriver.
Note: If you are using the rotary switch to assign a temporary IP address, you may want to leave the
door open until you use software to set a permanent IP address. After doing so, you can close
and seal the window.
The default setting is 000 as shown above.
The arrow points to the switch location. 0 is located at the 3:00
4. Carefully close the window making sure that it is properly aligned.
5. Reinsert and hand-tighten the two screws making sure that the window is securely sealed.
Note: Failure to reassemble the configuration window properly may compromise IP67 integrity.
2.2 Connecting to the Network
Use the appropriate procedure for your IO-Link Master model.
2.2.1 MD 748I-11-42/L5-2222 - Connecting to the Network
The IO-Link Master provides two Fast Ethernet (10/100BASE-TX), 4-pin female / D-coded M12 connectors.

You can use this procedure to connect the IO-Link Master to the network.
1. Securely connect one end of a shielded twisted-pair (Cat 5 or higher) M12 Ethernet cable to either
Ethernet port.
2. Connect the other end of the cable to the network.

3. Optionally, use the other Ethernet port to daisy-chain to another Ethernet device.
4. If you did not connect both Ethernet ports, make sure that the unused port is covered with a
connector cap to keep dust and liquids from getting in the connector.
Note: Ethernet ports must have an approved cable or protective cover attached to the connector to guarantee
IP67 integrity.
2.2.2 MD 248i-12-8K/L4-2R2K - Connecting to the Network
The IO-Link Master provides two Fast Ethernet (10/100BASE-TX) standard RJ45 connectors.

You can use this procedure to connect the IO-Link Master to the network or IO controller.
1. Securely connect one end of the RJ45 Ethernet cable to either Ethernet port.
2. Connect the other end to the network or an IO controller.
3. Optionally, use the other Ethernet port to daisy-chain to another Ethernet device.
Note: If you do not connect the IO-Link Master to an IO controller, an IO controller needs to be connected to the
network for PROFINET IO configuration.
2.3 Connecting the Power
Use the appropriate information for your IO-Link Master model:
2.3.1 MD 748i-11-42/L5-2222 - Connecting the Power
The MD 748i-11-42/L5-2222 provides dual M12 (A-coded) power connectors.
Note: Power connectors must have an approved cable or protective cover attached to the port guarantee to IP67
compliance.
