Section 2: Hardware Installation
Note: Refer to Section 5: Connecting Devices for information about connecting IO-Link or digital
devices to the ports after you program the network information using the next section.
2.1 IOLM Hardware Installation
Use the following subsections to install the hardware and verify operation.
•Setting the Rotary Switch (Section 2.1.1)
•Connecting to the Network (Section 2.1.2)
•Connecting the Power (Section 2.1.3)
•Mounting the IOLM (Section 2.1.4)
Note: Refer to Section 5.2IOLM IO-Link Ports for information about connecting IO-Link or digital
devices to the ports after you program the network information using the next section.
2.1.1 Setting the Rotary Switch
You can use the rotary switches under the configuration window on the IOLM to set the lower 3-digits
(8 bits) of the static IP address (192.168.11.XXX).
For example, the default IP address is 192.168.11.202. When the rotary switches are set to 000, the
final segment of the IP address will remain at 250. However, if the rotary switches are changed to 022,
then the IOLM module will obtain the IP address 192.168.11.22
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 the 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 IOLMs so that they do not have
duplicate addresses, making IP address configuration easier when using the web page. After
using the web page to change the IP address, reset the rotary switches back to 000.
•An emergency method to reset the IOLM to factory defaults, so that software can be used to
program the appropriate IP address, and then reset the switches 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 IOLM is initially powered on or after cycling the power.
Note: The default subnet mask is 255.255.255.0
Changing the Default Rotary Switch Settings
Use the following steps if you want to change the default rotary switch settings.
1. With a small flathead screwdriver, gently pop open the configuration window.
2. Gently swing open the switch window from the top to the bottom, allowing it to pivot on the
hinge on the bottom of the window.

Configuring 11
3. Turn each dial to the appropriate position using a small flathead screwdriver.
Figure 3: Rotary Switches
Note: The default setting is 000 as shown above.
4. The arrow points to switch location 0 is located at the 9:00 position. Turn the dial clockwise
to the appropriate setting.
5. Close the window and make sure that it snaps shut tightly.
Note: Failure to close the configuration window properly may compromise IP67 integrity.
Switch Setting
Node Address
000
(Default setting)
Use the network configuration stored in the flash. The default network configuration
values are:
IP address = 192.168.11.202
Subnet mask = 255.255.255.0
IP gateway = 0.0.0.0
After completing the hardware installation, see Section 3: Configuring the IOLM with PAC
Machine Edition 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 192.168.11.xxx.
Note: If the software is used to change the IP address to another range before setting the rotary
switches, the IOLM uses that IP address range. For example, if the IOLM 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 IOLM 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 IOLM is rebooted
or power cycled.
889-997
Use the network configuration values stored in the flash (reserved).
998
Setting the rotary switches to 998 configures the IOLM to use DHCP addressing.
999
Use the default IP address. If the IOLM 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 IOLM is rebooted
or power cycled.

You can use this procedure to connect the IOLM 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.

3.4 IP Address Assignment
RSTi-OM IOLM gateways support three methods for IP address assignment according to GSDML
Specification.
•DCP - The IOLM supports IP address assignment via Discovery and basic Configuration
Protocol (DCP). See 3.4.1 Assigning an IP Address via IO Controller (DCP) for procedures.
•DHCP - The IOLM supports the Dynamic Host Configuration Protocol for IP address
assignment. See 3.4.2, Assigning an IP Address via DHCP for procedures.
•LOCAL - The IOLM supports a device-specific method for IP address assignment. See Section
Assign IP Address Statically Using the Web Page.
3.4.1 Assigning an IP Address via IO Controller (DCP)
A PROFINET IO controller can assign an IP address to the IOLM gateway via DCP. The IO controller and
the Emerson IOLM gateway have to be on the same subnet. The IOLM default IP address is:
192.168.11.202 and the subnet mask is 255.255.255.0.
To assign IP address/device name from the DCP tool, navigate to Utilities menu item in PAC Machine
Edition and select PROFINET DCP
Figure 11: PROFINET DCP Utility
The PROFINET DCP dialogue will pop up. Select the appropriate connection to which the PROFINET
controller and IO device are connected. Click on Refresh Device List to list all PROFINET controllers and
IO devices connected.
