Overview and Specifications of Ethernet Interface

4.1 Introduction of Functions (Ethernet)
Connecting to the Network
The Ethernet Module DT300-41 can connect to a network conforming to IEEE802.3 through a
10BASE-T.
By connecting to a network, a PC also connected to the same network will be able to read the data
measured by the DR. However, to do so, the PC must have the following application software
installed.
Data Acquisition Software 32 (DP120 comes with the DR)
Data Acquisition Software 32 Plus (DP320 sold separately)
These applications are used to set the IP address and other parameters, read in the measured data
with the PC, and display various measurement information.
Note
• Because the IP address is not set at the time of shipment, an error will occur if you try to communicate without setting the
IP address first.
What You Can Do with the Ethernet module
You can do the following things by using the Ethernet module.
Read in the DR measurement data with the PC, configure and control the DR from
the PC (supports RS-232-C commands)
By using the Data Acquisition Software 32 or the Data Acquisition Software 32 Plus, you will be
able to read in the DR measurement data with the PC and configure and control the DR from the
PC. This is possible, because the Ethernet module supports all the commands that are supported
by the RS-232-C module.
You can also create an original program using the RS-232-C commands.
For details on the commands, see chapter 6.
Read in instantaneous value data
You can read in the current measured data with the PC.
Check the communication conditions
The following information can be displayed on the computer screen by using Telnet.
• Warning information.
• The socket address and connection state of the DR and the PC.
• Information about the network.
About the Ports
The Ethernet module uses separate ports for the three functions mentioned above. The number of
PCs that can connect (software connections) to each of the ports varies.
Function Port Number of Connections
RS-232-C command port 34150 1
Reading instantaneous value data 34151 4
Checking communication conditions 34159 1
