Warn WARNING
Use the Correct Power Supply
Ensure that the source voltage matches the voltage of the power supply before turning ON the power.
Connect the Protective Grounding Terminal
Make sure to connect the protective grounding to prevent electric shock before turning ON the power.
Do Not Impair the Protective Grounding
Never cut off the internal or external protective earth wire or disconnect the wiring of the protective earth
terminal. Doing so invalidates the protective functions of the instrument and poses a potential shock
hazard.
Do Not Operate with Defective Protective Grounding or Fuse
Do not operate the instrument if the protective earth or fuse might be defective. Make sure to check them
before operation.
Do Not Use in the Presence of Flammable Liquids, Vapors, and Dust
Do not use the instrument in the presence of flammable liquids, vapors, and dust. Operation in such
environments constitutes a safety hazard.
Do Not Remove Covers
The cover should be removed by YOKOGAWA’s qualified personnel only. Opening the cover is
dangerous, because some areas inside the instrument have high voltages.
Ground the Instrument before Making External Connections
Connect the protective grounding before connecting to the item under measurement or to an external
control unit.
Avoid Damage to the Protective Structure
Operating the instrument in a manner not described in this manual may damage its protective structure.

Chapter 1 Explanation of Functions
1.1 System Overview
MW100 Data Acquisition Unit
The MW100 Data Acquisition Unit consists of a main module equipped with an Ethernet
port, I/O modules for input and output of signals (these are the same as those for the
MX100 Data Acquisition Unit), and a base plate on which the first two items are mounted.
The main module comes with an HTTP server function, allowing users to easily enter
settings, acquire data, and monitor measured data from a PC using a browser. The
main module also comes with a Modbus/TCP function that allows multiple units to be
connected.
System Configuration
The MW100 Data Acquisition Unit can be flexibly configured for a variety of measuring
environments such as a small-scale system that acquires data onsite in a standalone
configuration or a system that allows data acquisition of up to 360 channels using the
Modbus/TCP function.
One-to-one Connection with a PC
This is an example of a system for small scale logging, setting the IP address, and other
tasks.

Main Module
The main module is equipped with power supply connectors, a power switch, Ethernet
ports, and other devices facilitating supply of power to and control of the input/output
modules, and connection to networks.
It also has Start and Stop keys, meaning that since data can be saved to a CF card, data
can be acquired offline. Data acquisition via serial communication is also possible by
adding the RS-232 or RS-422A/485 serial communication option.
Input/Output Modules
The following eleven types of modules are available. A screw terminal plate and
separately installed screw terminal block (both sold separately) are available as
accessories for the 10-CH Medium Speed Universal Input Module and the 10-CH High
Speed Digital Input Module.
4-CH, High-Speed Universal Input Module (MX110-UNV-H04)
• Minimum measurement interval: 10 ms (except 50 ms for
temperature measurement
• Maximum number of inputs: 4 inputs
• Input types: DC voltage, TC, 3-wire RTD, and DI (LEVEL,
non-voltage contact)
10-CH, Medium-Speed Universal Input Module (MX110-UNV-M10)
• Minimum measurement interval: 100 ms
• Maximum number of inputs: 10 inputs
• Input types: DC voltage, TC, 3-wire RTD, and DI (LEVEL,
non-voltage contact)
6-CH, Medium-Speed, Four-Wire RTD Resistance Input Module (MX110-V4R-M06)
• Minimum measurement interval: 100 ms
• Maximum number of inputs: 6 inputs
• Input types: DC voltage, 4-wire RTD, 4-wire resistance,
and DI (LEVEL, non-voltage contact)

• Minimum measurement interval: 100 ms
• Maximum number of inputs: 4 inputs
• Input system: floating balanced input (isolation between
channels)
4-CH, Medium-Speed Strain Input Module (MX112-NDI-M04)
• Minimum measurement interval: 100 ms
• Maximum number of inputs: 4 inputs
• Input system: floating balanced input
(non-isolation between channels)
10-CH, High-Speed Digital Input Module (MX115-D05-H10)
• Minimum measurement interval: 100 ms
• Maximum number of inputs: 10 inputs
• Input types: DI (non-voltage contact, open collector, 5-V logic)
10-CH, High-Speed Digital Input Module (MX115-D24-H10)
• Minimum measurement interval: 10 ms
• Maximum number of inputs: 10 inputs
• Input types: DI (24-V logic)

• Output update interval: 100 ms (shortest)
• Maximum number of inputs: 8 outputs
• Output type: DC voltage, DC current
8-CH, Medium-Speed PWM Output Module (MX120-PWM-M08)
• Output update interval: 100 ms (shortest)

• Maximum number of outputs: 10 outputs
• Output type: A contact (SPST)
Base Plate
The base plate is equipped with connectors for connecting the main module and input/
output modules. There are six types of base plates available (connecting from one to six
input/output modules ). By attaching DIN rail mounting brackets to the base plate, you
can rack-mount or panel-mount the MW100 main unit.

PC Software
The MW100 Data Acquisition Unit comes with the MW100 Viewer software program that
allows users to view measured data acquired by the MW100. MW100 Viewer consists
of the three software components described below. For a detailed description of the
functions of these software components, see the MW100 Viewer software user’s manual
(IM MW180-01E).
Address Setting Software
Sets the IP address on the MW100. This software is used when setting an IP address for
the first time, or if the current IP address needs to be changed.
Viewer Software
Enables you to (1) display measured, computed, and thinning data that has been stored,
(2) read values and perform computation over an area using cursors, and (3) convert the
measured and computed data into various file such as Excel.
Calibration Software
This software is used to calibrate the input/output modules connected to the MW100.
