6.1 Configuring With Ethernet Converter Setup Program
6.11 To start Ethernet Converter Setup program, click on StartProgramsEthernet
Converter Utility Ethernet_Converter_Setup
6.12 The Ethernet I/O Setup window is shown as below.
6.13 Click on the button to search all the Ethernet Converter connected
in the same subnet using the UDP broadcast protocol. When the search is finished,
the information about all Ethernet Converters found will be listed in the text box as
shown below.
14
6.15 The following window is displayed after double click on the desired Ethernet
Converter which allow user to modify the configuration of the selected Ethernet
Converter.
Please refer to the following description for setting up the parameters of the Ethernet
Converter.
Local IP:
The IP address of the Ethernet Converter on the TCP/IP network. The default
Local IP address is 192.168.192.250. This address should be unique. Ask your
network administrator for assistance, if in doubt.
Subnet mask:
Identifying the network class which the Ethernet Converter belongs to. The
default Subnet mask is: 255.255.255.0. Ask your network administrator for
assistance, if in doubt.
16
Gateway IP:
The IP address of the router. The default Gateway IP address is:
192.168.192.254.
Ask your network administrator for assistance, if in doubt.
DHCP client:
If this option is enabled, that means the IP address, Subnet mask and Gateway
IP address of the Ethernet Converter are set dynamically by the DHCP Server.
If the setting cannot be got from the DHCP server successfully, the Ethernet
Converter will use the last setup parameters for its configuration. The possible
reason of this case is that the DHCP server is shutdown or not available. Ask
your network administrator for assistance, if in doubt.
SIO Port, Type:
The local port number of the Ethernet Converter to be contacted by other
devices. The default port number is 502, which is reserved for Modbus/TCP
protocol that Ethernet Converter supports only. And default communication
mode for Ethernet Converter is TCP Server, which made Ethernet Converter
operate at the Passive or the TCP listen mode to receive TCP connection
requests from the remote client device.
Command Port:
The Ethernet Converter supports the command mode, which user can use to
setup the parameters or get the information of the Ethernet Converter with
UDP protocol from the remote host. The default Command Port number is
65535. The command port of the Ethernet Converter should be set correctly
while using the command mode. Please refer to appendix 1 for further
information.
Setup password:
This password protects the Setup window of the Ethernet Converter from
unauthorized entry. To erase an existing password, just leave the Setup
password text box blank.
Access password:
If this password is configured, the remote host needs to send this access
password one second periodically to the Check Status Port of the Ethernet
