Standalone MW100
Notice: This product was discontinued on Mar 31, 2019. See this replacement product:

Industrial processes often employ multiple data acquisition systems to monitor the health of assets and facility infrastructure. These systems can be either standalone or built as nodes within a larger automation topology.

The MW100 is a scalable, high performance data acquisition and data-logging platform designed for standalone, networked, or PC-based operation under industrial operating conditions. It supports remote web-based configuration and monitoring. With its DIN rail design, it is often mounted in an enclosure or cabinet.


"Smart Logging" - Anytime, Anyplace

The MW100 is a scalable, high performance data acquisition/data-logging platform designed for both PC-controlled and stand-alone operation under harsh operating conditions. Open Ethernet connectivity with web-based configuration and data monitoring functions allow MW100 to handle a wide range of monitoring and historical logging functions. See real time trends with your web browser from any PC and no special software. A full range of input/output modules handle all of your process inputs with fast measurement speed and high noise immunity for rock-solid performance.

Acquire up to 360 Channels in One System

Acquire up to 360 Channels in One SystemA large data acquisition system of up to 360 channels can be assembled using multiple MW100s and standard MODBUS TCP Ethernet communications. When equipped with the /M1 math option, the MW100 can acquire up to 300 channels of external data from additional MW100 units or other devices such as a PLC using MODBUS TCP communications. This provides a total system capacity of 360 channels (60 built-in measure channels + 300 external). 

Serial MODBUS RTU communications (RS- 232 or RS-422A/485) can be ordered as a separate option with the same capability.

Connect to Other Devices

Connect to Other Devices

An optional serial MODBUS RTU interface provides data exchange functions with other devices such as recorders, PLCs and controllers. In this mode, MW100 can serve as expansion I/O or as a data acquisition terminal for another connected device.

Remote Data Acquisition

Remote Data AcquisitionWhen the measurement location is located remotely from the data monitoring station, a dial up phone connection can be used for communications. All MW100 web browser-based data monitoring and FTP functions can be used via this connection for remote data acquisition applications. 

Screen updating may be slower depending on the communication environment.

Time Synchronization

Time SynchronizationThe MW100 can synchronize its clock to a network time-server using SNTP (Simple Network Time Protocol), allowing any number of MW100s in a system to have precisely matched time.

Both SNTP Server and Client modes are supported. In Server mode, one MW100 can acquire time data from a server using Client mode. It can then serve time data in Server mode to other MW100s that function as Clients.

Clock synchronization functions are allowed only when the measurement interval within the unit is two seconds or longer.


Select a CF card appropriate for the required data recording time. See the table below for the approximate time's worth of data that can be recorded for each size of card. For example, when recording ten channels of data at a 10 ms measurement interval, the approximate amount of data that can be recorded to a 128-MB CF card is 8.8 hours worth. On the MW100, measured data is recorded to the CF card via an SRAM. The SRAM is backed up with a battery (for approximately ten years), ensuring that even in the event of a power failure, data prior to the failure is not lost.

Storage capacity in terms of time by CF card size and numbers of channels

  1. At a measurement interval of 10 ms, the maximum number of channels that can be measured is 10. Eleven or more channels cannot be measured at a measurement interval of 10 ms.
  2. At a measurement interval of 50 ms, the maximum number of channels that can be measured is 30. Thirty-one or more channels cannot be measured at a measurement interval of 50 ms.



The MW100 enables mixing of three different measurement intervals in a single unit. Measurement intervals can be set for each individual module. This allows you to measure various items under test at the most appropriate measurement intervals. Also, you can set data recording conditions1 for each measurement interval, thereby using the available space on the CF card as efficiently as possible.

  1. Single: Save a file up to the specified size then stop recording. Full Stop: Stop recording once the CF card is full. Rotate: When the capacity of the CF card has been exceeded, the oldest files are deleted to free up space, then recording continues.

Trigger and Data Thinning Functions

Data Recording Using the Trigger and Data Thinning Functions

Data Recording Using the Trigger and Data Thinning Functions

The MW100 is equipped with built-in trigger functions. Data recording can be started based on alarm values, time, external contact input, or other parameters. Once recording is started, it can be set to progress continuously or according to a specified data length. When specifying a data length, a pre-trigger can also be set. The MW100 also provides a data thinning function. 

Portions of measured data can be omitted at regular intervals during measurement (minimum of four seconds) before data is recorded. Using the trigger and data thinning functions together provides "coarse" recording of general data and "fine" recording of abnormal data.

Broken Line Chart Output (/M1 Option)

Data Recording Using the Trigger and Data Thinning Functions

This function is included with the MATH (/M1) option. Patterns can be output from the analog output and PWM output modules (MX120) by inputting the coordinates of the pattern you wish to generate. In the pattern output shown in the figure below, points (X1,Y1) through (X10,Y10) are input in advance, and the output is generated accordingly.

Reporting Functions

Creates hourly, daily, weekly, and monthly reports synchronized to measurement start and stop. On mesurement stop action, a report file is saved to the MW100 CF media. A report status display is provided in the web browser monitor mode. Report data is saved to a text (.txt) file compatible with common software applications. 

Up to 60 report channels reporting data from assigned measure or math channels

Report channel data: MIN, MAX, average, summation, and instantaneous values
Report channel data: tabular digital data display and graph for totalizer data
File format: .txt text file (tab delimited)
Report math interval: up to 100 ms
Email messaging: An email message is sent at the report creation time

MW100 Automatic Assignment Function (/MC1 Option for the DXAdvanced DX2000)

The DX2000 can use MW100 system hardware as additional external input channels. They can automatically recognize MW100s on a network and perform automatic assignment of the MW100 input channels to build a large multi-point data acquisition system quickly and easily with no PC requirement. System requirements: /MC1 external input option and /M1 math option. See the product bulletins and general specifications for details.

Standard Support for the EtherNet/IP Protocol

Advantages of EtherNet/IP Compatibility

  1. Able to develop a highly flexible systems
    By using Ethernet/IP in the standard interface, the most appropriate multivendor systems can be readily developed for users. In addition, instruments can be added or modified without any additional programming, thus improving efficiency.
  2. Improved trend analysis
    By making it easier to install the MW100 Data Acquisition Unit in systems and thereby facilitating the chronological monitoring of equipment operating conditions and quality data, trends can be analyzed with higher precision.
  3. Transmission of vast amounts of data at high speeds over a wide area
    Data can be regularly transmitted at high speeds to instruments distributed over a wide area.
  4. Easy maintenance over a network
    With Ethernet, maintenance staff do not need to learn a dedicated protocol for each instrument, making it easier to control the network.

Note 1: You must install firmware R3.02 to use EtherNet/IP with the MW100.

Note 2: EtherNet/IP is an open industrial application layer protocol supported by ODVA (Open DeviceNet Vendor Association).

Addition of User Authorization to the SMTP Authorization Function

A user authorization feature has been added to the SMTP Authorization function. SMTP authorization (SMTP Service Extension Authentication: SMTP AUTH) means that verification is made when sending e-mails so that only successfully authorized users can send e-mail. This newly added authorization function serves to further strengthen security for sending of e-mails.
