Main Unit Recording Function
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|
- 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.
- 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.
- 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
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)
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.
New Functions for Style S3
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|
|File transfer:||the report file can be transferred to an FTP server at the report creation time|
Report logging display
Graph Display of totalizer data
Use Excel or other applications to create custom reports from the report text file.
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.
*The firmware version of R2.22 or later is required for the MW100 to support the automatic assignment function.
Firmware R3.03 Functions
|Line Monitor:||Enables monitoring with a digital display, even in environments with low transmission speeds.|
|Setting List:||A list of settings that can be displayed in TXT (text) or "printable" format.|
|Bit output computation:||Enables output of the value of specified bits (0/1) of reference channel data (positive integers expressed as bits).|
|Alarm Do output:||Preset settings of Off, Open, and Close were added as operations upon stop or error.|
|Modbus Slave/Server Function:||
|Summer Time Setting:||The starting and ending date/time for Summer time can be set.|
Firmware R3.02 Functions
Standard Support for the EtherNet/IP Protocol
Advantages of EtherNet/IP Compatibility
- 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.
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.
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.
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.
