1. Overview
MG80-EI is an interface unit main module which enables acquisition of the multi-axis
measurement data by connecting with a PC or PLC via EtherNet/IP communication
protocol. This manual explains the setup procedure and detail of the functions.
For specification of MG80-EI, MG80-CM and LZ80, refer to the instruction manual of
each product. For detail of EtherNet/IP communication with PC or PLC, refer to the
manual of the each manufacturer.

2. Basic informaion
EtherNet/IP uses the terms “scanner” and “adapter” in place of “master” and “slave”,
respectively. MG80-EI is the adapter.
This section shows the adapter (MG80-EI) side components and its configuration,
which names and terms also appear in other sections of this manual.
2.1. System configuration
The following diagram shows the example of maximum configuration using MG80
series lineup. A counter module MG80-CM is necessary for a connecting a measuring
unit, and I/O module LZ80-K1/K2 which enables control of the units with external
signal, are available for configuration with MG80-EI.

Maximum configuration(1unit)※:
MG80-EI×1, MG80-CM×16, LZ80-K1/K2×2
※Up to 255 units(4080axis) can be connected
Measuring unit No. １・・・・・・・・・・・15 16
・Up to 16 counter module MG80-CM can be connected to one MG80-EI.
・Connect the measuring unit DK series to MG80-CM.
・Measuring unit numbers are automatically assigned in order from 1 closest to MG80-EI.
・For EtherNet/IP or Ethernet connection, prepare a shielded cable with RJ-45(8P8C) connector.
(Both straight and cross cables can be used.)
・The number of connectable unit depend on the available lower 1byte of the IP address.
If the available IP address is 1 (0x01) to 255(0xFF), maximum of 255units of MG80-EI
(4,080 axes of measuring units) can be connected.

3. Setting
3.1. Download setting application and EDS file
1. Access Magnescale Website and download the necessary files.
(https://www.magnescale.com）
Application for Windows PC “MG80SettingTool.exe”
「Products」
→「Digital Gauge」
→「MG80-NE/EI/PN MG80-CM」
→「Software」
Click 「Download」 under “Setting application for Windows PC*2”.
EDS file for EtherNet/IP communication
「Products」
→「Digital Gauge」
→「MG80-NE/EI/PN MG80-CM」
→「Software」
Click 「Download」 under “Setting file*1”.
EDS file can be used regardless of the PLC manufacture and the number of
axes used.
2. Save the files and extract with decompression software.
3.2. About IO data
When EDS file is imported to the development environment, the IO data is
handled as Byte array data. Refer “6. Communication” in this manual for IO data
mapping.
3.3. Setting various parameters
Setting for MG80-EI can be changed with the application for Windows PC
“MG80SettingTool.exe”.

7
3.3.1. Connecting MG80-EI with PC
1. Place the downloaded files in the suitable location of the PC.
2. Set IP address of the PC as shown below.
IP address ：192.168.100. xxx※
Subnet mask ：255.255.255.0
※Values to avoid in XXX
- “1” (It will be used by MG80-EI in setting mode)
- Same address with other connecting devices.
3. Set MG80-EI IP address switches to “0x00”. This will activate the setting
mode. In this mode, IP address will be fixed as shown below.
IP address ：192.168.100.1
Subnet mask ：255.255.255.0
4. Connect PC and MG80-EI directly with the Ethernet cable.
Then connect power supply to turn on the MG80-EI.
5. Click “MG80SettingTool.exe” in the PC and start the application.

Follow the steps below to connect with the MG80-EI.
1. Click the Start button at the top right corner.
2. Click the Connect button.
3. If the connection is successful, “Network settings” and “Parameter” field will
become valid.
If the connection fails, turn off MG80-EI power and close PC application, then restart
the procedure.

10
4. Follow the steps below to change the MG80-EI Network Settings.
The IP address set in this field will be applied in the actual measuring environment.
The lowest 1byte of the IP address (In this case “1”) must also be set with the switches
on the MG80-EI, after setup with this software.
Enter the settings as in red frame above, then click “Set” button to transfer the
information to the MG80-EI.
*Note
IP address = IP address
Network mask = Subnet mask
Gateway address = Default gateway
Click “Get” button to confirm the settings saved in the MG80-EI.

11
3.3.2.1. Measurement parameter setting
Make sure the Parameter field is valid.
If the field is not valid, restart the connection procedure.
If there are multiple pages on the parameter screen, switch pages by pressing the
page forward/backward buttons.
After setting the parameters, click the “Set” button at the bottom of the screen to
save the parameters in MG80-EI.
Note) Make sure to click the “Set” button in each screen, or parameters will not
be save in MG80-EI.
Click “Get” button in the bottom, to make sure the parameters are properly saved.
