1. Introduction
MG80-PN is an interface unit main module that can easily acquire multi-axis
measurement data by connecting to a PC or PLC via PROFINET interface.
It is compatible with the existing product MG70-PN in terms of communication.
When using MG70-PN, the program used in MG80-PN can be used continuously.
This manual describes the details of the functions and the communication setting
method.
For MG80-PN, MG80-CM and LZ80, refer to the attached instruction manual of each
device.
For basic information of PROFINET, refer to the manual of each PLC manufacturer.

2. Basic information
In PROFINET, the master device is called a “IO controller” and the slave device is
called an “IO devices”. MG80-PN belongs to IO Devices.
This section describes the connection configuration of MG80-PN and various
connected devices.
2.1. System configuration
MG80-PN can be connected to a counter module MG80-CM for connecting a
measuring unit, and an I/O module LZ80-K1/K2 that can control the operation of
the constituent units and external signals.
Master
PC, PLC
PROFINET or
Ethernet cable
(MG80-PN side
RJ45 connector)
Measuring unit
Maximum configuration (1unit)※:
MG80-PN×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-PN.
・Connect the measuring unit DK series to MG80-CM.
・Measuring unit numbers are automatically assigned in order from 1 closest to MG80-PN.
・For PROFINET or Ethernet connection, prepare a shielded cable with
RJ45(8P8C) connector. (Both straight and cross cables can be used.)
・The number of connectable units depends on the available number of 1(0x01)to 255(0xFF),
in which the lower 1byte of the IP address can be set.
If the IP address can use 1 to 255, maximum 255 units (4080 axes) can be connected.
・Be sure to use Port 1 for PROFINET connection with the master side and host side.

3.1. Download of setting application and GSDML file
1. Access to Magnescale Web
(https://www.magnescale.com/mgs/language/english/）
「Products」
→「Digital Gauge」
→「MG80-NE/EI/PN MG80-CM」
→「Software」
Download the Setting application from “Setting application for Windows PC”
As above
「Products」
→「Digital Gauge」
→「MG80-NE/EI/PN MG80-CM」
→「Software」
Download the GSDML file from “Setting file”
GSDML file can be used regardless of the PLC manufacture and the number
of axes used.
2. Save the file in an appropriate location and extract it with decompression
software.
3.2. About IO data
When the GSDML file is imported into the development environment, the IO data
is handled as Byte array data. Please refer to “6. Communication” page of the
text for IO data mapping.
3.3. Setting various parameters
Various settings of MG80-PN can be performed from PC by using
“Setting application for Windows PC”

6
3.3.1. Connection
1. Preparation of "setting application for Windows PC"
Please place the downloaded "MG80SettingTool.exe" file in an arbitrary
location.
2. Make the following settings on the PC which “the setting application for
Windows PC” is installed.
IP address ：192.168.100. xxx※1
Subnet mask ：255.255.255.0
※1 Address that cannot be set to XXX
- “1” that is used when setting with the MG80-PN.
- Same address as other connected devices.
3. Set the setting switch to “0x00” to enter the setting mode and enable
communication with the computer.
In this case, the IP address is fixed to the following.
IP address ：192.168.100.1
Subnet mask ：255.255.255.0
4. Connect the PC which “Setting application for Windows PC”” is installed and
MG80-PN directly with Ethernet cable.
Connect the power supply and turn on the MG80-PN.
5. Click "MG80SettingTool.exe" on the PC on which "Setting application for
Windows PC " is installed to start the application.

Follow the steps below to connect to the setting application for Windows PC.
1. Click the Start button at the top right of the setting application.
2. Click the Connect button at the top right of the setting application.
3. If the connection is successful, the network setting field and parameter setting
field become valid.
If the connection fails, turn off the power of the MG80-PN and start again from the
setting application.

3.3.2.1. Measurement parameter setting
Check that the following parameter setting fields are active.
If not, redo the connection procedure described in the previous section.
If there are multiple pages on each parameter screen, switch pages by pressing the
page forward buttons.
After setting the parameters on each parameter screen, click the “Set” button at the
bottom of the screen to send and save the parameters to MG80-PN
Note) If you do not click the “Set” button, it will not be saved in MG80-PN, so
be sure to execute it on each screen.
By pressing the “Get” button at the bottom of each parameter screen, you can get
the parameters currently saved in MG80-PN.

※“Frame” is a function that can be set the measured value or calculated
value of the measuring unit in a prepared frame and call it with Explicit
communication. The details are described in 5.2 on the next page.

18
5.2. Frame definition
A frame is a constituent unit that can be used as an output value by freely
selecting the calculated value, current value, peak to peak value, maximum
value, and minimum value.
Up to 16 frames can be set for each unit (maximum connection configuration:
MG80-PN x1, MG80-CM x 16, LZ80-K1/K2 x2).
Each of the 16 frames is called a frame number from A to P.
Each frame can be read as RT communication of PROFINET.
By setting the output value for each frame in advance, it can be read at any
time during measurement.
The following is a setting example.
16 frames (frame number : A to P)
The contents to be output can be freely selected and set in one frame.
The frame setting method can be set as various operation parameters in the
Setting application for Windows PC.
The frame can be set freely from 1 to 16 regardless of the number of MG80-CM
connections.
For example, the same set contents can be set in multiple frames.
（Note）
-Calculations between different frames, such as adding frame A and frame B,
cannot be performed.
-The calculation function can be used only in one unit (MG80-CM connected to
MG80-PN).

5.3. Detail of function
5.3.1. Peak hold
The peak value (maximum value, minimum value, peak to peak value) of each
frame is always retained.
An example of calculating the peak value is shown below.
When the measuring unit moves from left to right as shown below, the black line
is the current value, red line is max. value and blue line is min. value.

Operation examples of Peak hold
Each time the current value is obtained, the value is updated to satisfy
the following conditions and stored in RAM.
Minimum value ≦ Current value ≦ Maximum value
Peak to peak value＝Maximum value－Minimum value
