Chapter 1 Introduction
This document provides instructions and examples on how to configure a system consists of Rockwell
ControlLogix PLC, an ICC ETH-1000 Gateway, and Mitsubishi iQ PLC system. An Example of the system
configuration is shown in Figure 1 below.

The system configurations enable Rockwell PLCs to read and write both bit and register data of Mitsubishi iQ
PLC using either EtherNet/IP Implicit or Explicit Messaging protocols. Both the built-in Ethernet port on an iQ
CPU and an external Ethernet module can be used for this communication.

ICC ETH-1000 Gateway module is used to convert the EtherNet/IP protocol to Mitsubishi MELSEC
Communication (MC) Protocol that is supported by Mitsubishi iQ PLCs.
It is assumed that the user of this guide is familiar with the Rockwell RSLogix5000 environment, the
operation of Mitsubishi iQ PLCs, and has sufficient knowledge of the ICC ETH-1000 Gateway. It is critical
for the users to refer to the manuals when setting up the system parameters for EtherNet/IP applications.

Chapter 2 System Overview
A Verification System is used as a test bed for verifying the steps documented in this Quick Start guide. The
Verification System is shown in Figure 2 below with the IP address assignments of all the devices.

Figure 2 Architecture of an Example Verification System
The Verification System consists of one monitoring PC (e.g. Monitoring Laptop 1), a ControlLogix system, an
ICC ETH-1000 module, and one Mitsubishi Q13UDEH PLC system.
The following list contains high-level steps to establish proper EtherNet/IP communication of this Verification
System. Each of these steps will be further detailed in subsequent chapters
1. Connect the programming/monitoring PC, Rockwell PLC, ICC ETH-1000, and Mitsubishi PLC system to
the Ethernet network
a. Configure all devices to have proper IP addresses and subnet masks as shown above.
b. Ensure that RSLogix5000, ICC Gateway Configuration Utility, and Mitsubishi GX Works2 or GX
Developer software packages are installed on the programming PC.
2. Create a project using the RSLogix5000 software to interface with the Mitsubishi PLC.
a. Add the ICC ETH-1000 as a Generic Ethernet Module in the RSLogix5000 project.
3. Configure ICC ETH-1000
a. Configure EtherNet/IP Parameters
b. Map the ControlLogix Tags for the ETH-1000 to the internal ETH-1000 database locations
c. Map ICC ETH-1000 internal database locations to proper controller register and/or bit locations
for the PLC.
4. Configure iQ system
a. Configure the Built-in Ethernet port on the iQ CPU
b. Configure the Ethernet port on an external Q71E71 module if necessary

Chapter 3 Connecting Devices to the Network
The steps of configuring the IP addresses of the ControlLogix PLC system, the ICC ETH-1000 module, and the
PLC are documented in this chapter.
3.1 Changing the IP Address of the ControlLogix System
The minimum configuration of a ControlLogix system consists of a ControlLogix chassis (e.g. 1756-A7), a
power supply (e.g. 1756-PA72), a ControlLogix Controller (e.g. 1756-L61), and an EtherNet/IP module (e.g.
1756-ENBT).
The steps here document the procedure to modify the IP address of a 1756-ENBT module to add the
ControlLogix system on the same network with the Mitsubishi PLC and the ICC ETH-1000 module. It is
assumed that there is already an IP address assigned to the ENBT module. If configuring a brand new
ENBT module is necessary, please consult the user manual of the Rockwell ENBT module.
1. Power on the Rockwell system and monitor the display scrolling across the front of the ENBT
module. If the module is working properly, the message “OK Rev x.x.x IP1.IP2.IP3.IP4” should scroll
across the display. Rev x.x.x is the revision number of the module firmware, and IP1.IP2.IP3.IP4
forms the current IP address of the module. For example, the message is “OK Rev 2.3.1
192.168.1.30”
2. Connect a configuration PC on the network. Change the IP address of the PC to be in the same
subnet as the 1756 ENBT module.
• Note: it is assumed that changing the IP address on a PC is known by the users of this
manual. If required, please consult Windows OS Help File.
3. Open the RSLinx Classic on the configuration PC and select Communications -> RSWho and
expand the tree to see the following screen showing the system configuration:

4. Right-Click on the ENBT Module and select “Module Configuration” from the drop down list:
5. Under the “Port Configuration” tab, select the Network Configuration Type to be “Static”, and one
can modify the IP address and the Network Mask to the desired values. Click “OK” and save the
new IP address configuration. The new IP address should scroll across the front of the ENBT
module.
3-2
6. Once the new IP address is set, it is very likely (depending on what IP address and Network mask
were assigned to the ENBT module) that the Configuration PC will no longer be able to
communicate with the ENBT module. The IP address of the Configuration PC will need to be
changed to be in the same subnet of the ENBT module before the communication can be reestablished.
3.2 Changing the IP Address of the ICC ETH-1000 Module
The “ICC Gateway Configuration Utility” should be loaded on a Configuration PC that is used to configure
the ICC ETH-1000. The ETH-1000 module can be powered using an USB connection, a Power Over
Ethernet (POE) connection or an external 7- 24V power supply.
Using the USB connection between the Configuration PC and the ICC ETH-1000 is the most straightforward
method to perform the initial configuration of the ICC Module.
1. Launch the “ICC Gateway Configuration Utility” on the Configuration PC and connect a USB cable
to the ICC device.

2. Click the “Auto Connect” button, and the ETH-1000 module will be connected, and the screen will
be populated with the current information:
The proper device type is shown with a green LED lit showing the connection has been established.
The firmware type, version, and Database type are also shown on the screen.
3. The user can modify the IP address and Subnet Mask information on this screen.
4. After making the changes, select the Download Configuration to Device button to load the new
configuration to the ETH-1000. A warning message will pop-up, select OK to continue download the
new IP address

5. After the download, the system will need to be reset for the changes to take effect. Click “Yes” to the
pop-up message and the ETH-1000 will go through the reset sequence

6. After the ETH-1000 system reboot, the screen should show the new IP address. In this example,
the IP address was changed to 192.168.5.190.
