Full Set of communications to support Data Acquisition
Datum-Y supports standard protocols such as HTTP, FTP, SMTP
and SNTP based on Ethernet connection (10BASE-T, 100BASE-TX),
so no dedicated software is necessary.
You can also use the user authentication function to permit access
only to pre-registered users, in order to prevent illegal access to
Datum-Y from networks. Up to seven users (one administrator and
six users) can be pre-registered.
Web Server Function
You can monitor and operate Datum-Y’s screens
and functions via a web browser. The monitor
screen can be updated automatically (every 5, 10 or
30 seconds) or manually. Select the monitor page
where Datum-Y screens can be monitored, or the
operator page where both monitoring and operation
are possible. User authentication can be set for each
page to prevent illegal access.
FTP Server Function
You can output a list of files stored in Datum-Y’s internal
memory or connected external storage media, and
transfer, delete or otherwise manipulate desired files.
FTP Client Function
You can transfer the measurement data files/alarm
data files created in Datum-Y’s internal memory or
connected external storage media, to a FTP server.
Two file transfer destinations can be set (primary
and secondary). If the primary FTP server goes
down, files will be transferred to the secondary FTP
server
E-mail Delivery Function
You can send e-mail to notify occurrence/reset of
alarms, power recovery after outage, errors in
external storage media, FTP client errors, and
scheduled times. Up to two groups can be set, each
containing a different set of recipients.
RS485, RS232
Built-in Modbus Protocol Capability
Serial communication (RS-232, RS-485) can be
performed using a dedicated protocol as well as
Modbus RTU and Modbus ASCII protocols that
are supported by Datum-Y’s standard capability.
Datum-Y can be connected to other equipment
to acquire data simultaneously with
temperature /
voltage. 32 dedicated
communication channels are provided.
USB
Datum-Y connects
with a PC. You can acquire
data, change Datum-Y settings
or perform various other
operations on Datum-Y from a
PC.
Printer
RS-232 (Printer)
You can connect a printer
via RS-232 connection to
print paper reports on site. |

| The Yokogawa Datum-Y portable data logger directly measures and acquires temperature (thermocouple/resistance temperature detector) and DC voltage. It provides two configurations of input terminals offering 8 and 16 channels, repectively individual channels can be set independently through universal insulated inputs. The Datum-Y is designed to achieve high performance and easy operation on site. Datum-Y provides wide ranging funtions and various communication capabilities to support diverse data acquisition applications. |

- All Channels Adopt Universal Insulated Inputs
The channels in the analog input part adopt insulated inputs, which means that
temperature (thermocouple/resistance temperature detector) and voltage can be
set differently for each channel. The digital inputs are equipped with one pulse
channel and two logic channels.
- Best-In-Class Noise Resistance
Datum-Y achieves excellent noise resistance rated among the best in the class of handy
measuring products. With Datum-Y, stable measurement is possible in various noise
environments, such as when measuring inverter-driven machines or thyrister-controlled units
that are commonly used for energy-saving purposes.
- Data Saving at 100ms
Datum-Y saves data at the maximum speed of 100 ms (when the 8-channel terminal block is
used).
You can save data in either binary format or ASCII format (for display in Excel*). Binary data
can be checked on site in the review mode or shown in waveforms using the supplied “D-TOOL” software.
- Acquisition of Large Amounts of Data
Using External Storage Media
Acquisition of Large Amounts of Data Using External
Storage Media
Datum-Y lets you save data not only in its internal
memory (16 MB), but also in external storage media
such as compact flash memory cards* and SD cards*
(up to 512 MB).
Data saved in these media can be copied to a USB
memory* for easy transfer to a PC.

- Spot Chech of Acquired Data
You can check measured data (binary) on Datum-Y right
away. Overall trend and alarm output can be checked on
the spot immediately after acquisition.
- While Datum-Y is logging data, you can display past data
and current data in the logging review mode for
comparison and identification of trend.
(This function is
available only when binary data is acquired.)
- Calculation Function
Datum-Y is capable of inter-channel calculations (among channels, between
channels and constants, etc.), statistical operations (minimum, maximum, average,
root-mean-square and peak values from start to end of logging), and scaling.
- Trigger Function
Datum-Y acquires data before and after a trigger (pre-trigger/trigger delay) to help you
detect and analyze the cause of an error. You can select the single mode (a trigger is issued
only once) or continuous mode (a trigger is issued every time the condition is satisfied).
- Alarm Function
Datum-Y can be fitted with up to four alarm output channels. One alarm can be set for
each input channel, and multiple channels can be combined freely with AND/OR
gates. You can also use the e-mail delivery function to notify specified e-mail
addresses upon occurrence or reset of an alarm
- Auto Set and Run Function
Simply connect an external storage medium (CF card, SD card or USB memory)
containing a predefined file (AUTORUN.SET), and Datum-Y will change the
necessary settings and take measurements automatically. (You need to enable the
automatic measurement function of Datum-Y beforehand.)
