Introduction
This Technical Information (TI) describes the overview and functions of the DAQSTATION
DX100/DX200.
Please read this document to fully use the capabilities of the DX100/200.
Companies today face a growing number of challenges – reducing total cost of ownership (TCO),
improving efficiency, and controlling quality. As these needs increase, companies must deal with a growing
amount of information needed to make informed decisions.
Conventional industrial recorders have been used primarily to monitor and record data in the field. In order
to quickly extract information that is valuable to a user from this sea of data, recorders need to be made
intelligent. This means they need to have advanced information processing and communication
capabilities.
The DX Series of DAQSTATION represents a leading-edge solution for 21st-century field data stations
from YOKOGAWA, the worldwide leader in recorder technology.
1Features
Network capability
Since Ethernet is supported as a standard, installation in an existing LAN/WAN environment is quick.
FTP transfer of data files is possible with the FTP client/server functions. In addition, data files can be
periodically and automatically transferred to an FTP server.
By connecting the DAQSTATION to a network, auto transfer of data, centralized management, and
remote data monitoring can be carried out. Reliability is improved by the duplication of data files and
cost reduction is achieved in terms of data collection.
A wide variety of display options
High visibility has been achieved by using 5.5-inch and 10.4-inch high-resolution color TFT monitors on
the DX100 and DX200, respectively.
In addition to trend displays, there are various other display functions including bar graphs, numeric, and
overview displays. You can select the optimal display for the conditions present.
Storage options for greater flexibility
The DAQSTATION lineup contains models that support external recording media other than 3.5" floppy
disks such as flash ATA memory cards and Zip disks. Zip is best suited to long-term data storage while
flash ATA memory card is best suited to harsh operating conditions.
In addition, only the necessary data can be stored, thanks to the abundant file formats and trigger
functions.
Rugged construction for high reliability
"Reliability that exists even in the toughest conditions." YOKOGAWA takes pride in providing the most
reliable products.
All measured data are stored to the flash memory, which does not require battery backup. In addition,
measured data are periodically stored to the external recording medium and, at the same time,
measurement data files are automatically transferred to an FTP server. In addition, the front section of
the case conforms to the IP65 and the NEMA4 standard, which shuts out power dust and even jet
streams. The DAQSTATION is reliable in all sorts of field conditions.

2.1.2 Run Mode
The DX Series has three types of modes depending on the level of operation.
Operation Mode
This mode is used during normal monitoring operation.
Most operations such as switching the displayed group
or display types are performed using the operation keys.
Operations such as alarm acknowledgement, message
entry, and screen snapshot are carried out by displaying
a menu with the [FUNC] key and then using the soft
keys.
SET Mode
This mode is used to change settings that are changed
often such as the range and waveform update rate. The
[MENU] key is used to display the setting parameters.
Parameters that affect the data that are being recorded
cannot be changed unless the recording is stopped.
This prevents erroneous operation.
SETUP Mode
This mode is used to change the operating environment
of the DX100/DX200 such as the input format or
recording format.

A section of the display is expanded in order to separate the sections of the analog waveform that you wish to
view in detail from the other sections.
Boundary of portion to be expanded/compressed : 1 to 99%
Boundary value : within the display span
As can be seen from these figures, the lower side of the boundary (0V) shows at 30% of the full
span of the screen the data in the range –6V to 0V. On the upper side of the boundary, the range 0V
to 6V is shown at 70% of the full span of the screen. Thus the scales differ on the upper and low
sides of the boundary.

Scale specifications（DX100）
Scale display position
On the trend display, the scale display position for the channels that are assigned to groups can be
displayed in 6 different positions.
Trend vertical display：1,2,3,4,5,6 from the top.
Trend horizontal display：1,2,3,4,5,6 from the right
If the scale for two or more channels are specified to the same position, the scale for the channel that was
assigned first to the group is displayed.
Example 1 Ifthechannelswereassignedtoagroupinthefollowingorder:[03.02.01.05]
If the scale display position for channels 3, 2, 1, and 5 are all set to [1], the scale
for channel 3 is displayed at position 1.
Scale marks
The scale can be divided into 4 to 12 sections using the main scale marks. The area between the main scale
marks is divided further into 10 sections using small and medium marks. When the main scale marks is
divided into 6 to 12, the main scale marks is divided into 5 sections by small marks.
However, small marks are not displayed for the following cases:
・When the measurement/computation range resolution is smaller than the total number of
sections created by small marks.
・When zone display is used.
・When partial expanded display is used.
Scale value
The scale values are displayed at all main scale marks when the scales divided into 4 to
7 sections using the main scale marks. When scale is divided into 8 to 12 sections, the scale
values are displayed at every other main scale mark. In addition, the upper or lower limit
of the scale is displayed at the end of the scale.
Rule 1 Up to 4 digits excluding the minus sign can be displayed at the end of the scale.
Rule 2 If the integer section of either value at the end of the scale is less than or equal
to one digit, the value is displayed as □.□or 0.□□.
Example 1 If the scale is set to -0.05 to 0.50, the scale display for the upper and
lower limits is -0.0 to 0.5
Example 2 If the scale is set to -0.005 to 0.05, the scale display for the upper
and lower limits are -0.0 to 0.0.
Rule 3 If the integer section of either value at the end of the scale is greater than or
equal to tow digits and less than four digits, the value is displayed with the decimal
fraction is discarded.
Example 3 If the scale is set to 0.1 to 100.0, the scale display for the upper and
lower limits is 0 to 100.
Rule 4 If the integer section of either value at the end of the scale is greater than or
equal to five digits, a four-digit mantissa and exponent are displayed(×10 or
×102)
Example 4 If the scale is set to 10 to 2000, the scale display for the upper and
lower limits are 1 to 200×10.
Rule 5 If the different in the number of digits between the upper and lower limits of the
scale is larger than the number of digits that can be displayed, the smaller value
is set to zero(0, 0.0).
Example 5 If the scale is set to -0.0005 to 0.5000, the upper and lower limits of
the scale are displayed as 0.00 to 0.50

Trend horizontal display：1,2,3,4,5,6,7,8,9,10 from the right
If the scale for two or more channels are specified to the same position, the scale for the channel that was
assigned first to the group is displayed.
Example 1 If the channels were assigned to a group in the following order: [03.02.01.05]
If the scale display position for channels 3, 2, 1, and 5 are all set to [1],
the scale for channel 3 is displayed at position 1.
Scale marks
The scale can be divided into 4 to 12 sections using the main scale marks. The area between the main scale
marks is divided further into 10 sections using small and medium marks.
However, small marks are not displayed for the following cases:
・When the measurement/computation range resolution is smaller than the total number of
sections created by small marks.
・When zone display is used.
・When partial expanded display is used.
Scale value
The scale values are displayed at all main scale marks when the scales divided into 4 to
7 sections using the main scale marks. When scale is divided into 8 to 12 sections, the scale
values are displayed at every other main scale mark. In addition, the upper or lower limit
of the scale is displayed at the end of the scale.
Rule 1 Up to 4 digits excluding the minus sign can be displayed at the end of the scale.
Rule 2 If the integer section of either value at the end of the scale is less than or equal
to one digit, the value is displayed as □.□or 0.□□.
Example 1 If the scale is set to -0.05 to 0.50, the scale display for the upper and
lower limits is -0.05 to 0.50
Example 2 If the scale is set to -0.005 to 0.05, the scale display for the upper
and lower limits are -0.00 to 0.05.
Rule 3 If the integer section of either value at the end of the scale is greater than or
equal to tow digits and less than four digits, the value is displayed with the decimal
fraction is discarded.
Example 3 If the scale is set to 0.1 to 1000.0, the scale display for the upper and
lower limits is 0 to 1000.
Rule 4 If the integer section of either value at the end of the scale is greater than or
equal to five digits, a four-digit mantissa and exponent are displayed(×10 or
×102)
Example 4 If the scale is set to 10 to 20000, the scale display for the upper and
lower limits are 1 to 2000×10.
Rule 5 If the different in the number of digits between the upper and lower limits of the
scale is larger than the number of digits that can be displayed, the smaller value
is set to zero(0, 0.0, or 0.00).
Example 5 If the scale is set to -0.0005 to 0.5000, the upper and lower limits of
the scale are displayed as 0.00 to 0.50
