Introduction to Functions
Measured Items
You can connect DC voltage, thermocouple, RTD, and ON/OFF input and measure
various values such as temperature and flow rate. The DX samples the input signals at
the scan interval to obtain the measured values. The fastest scan interval is 25 ms on the
DX2004T and DX2008T and 125 ms on the DX2010T, DX2020T, DX2030T, DX2040T,
and DX2048T.
Up to four alarm conditions can be set for each measurement channel.
Data Storage Function
There are two methods of recording measured data. One is to record the measured data
continuously, and the other is to record only when certain events occur such as alarms.
The measured data is recorded to the internal memory at a specified interval. The data in
the internal memory can be stored to a CF card automatically or manually. By connecting
to a network via the Ethernet interface, the measured data can also be automatically
transferred to an FTP server on a network.

Display Function
Measured data can be displayed as trends, numeric values, and bar graphs for each
group. In addition, the overview display can be used to display and monitor all channels
on a single screen.

Other Functions
Computation Function (option)
Various types of computation can be performed by
assigning equations to computation channels.
FAIL/status output function (option)
Outputs an alarm when the DX fails. The function
also monitors the DX status such as the remaining
amount of internal memory and outputs alarms.
Remote control function (option)
A specified action is executed when a remote input
signal is applied to the terminal on the rear panel.
Security function
Enables only registered users can operate the
DX. The function can also be used to prohibit key
operation.
Communication function
The Ethernet interface can be used to monitor the
DX using a Web browser and transmit e-mail when
an event occurs such as an alarm. In addition,
data of devices on the network can be loaded and
displayed using the Modbus protocol.
DAQSTANDARD
The accompanying software program, DAQSTANDARD, can be used to display the
measured data, convert the measured data format, and create DX setup data.
