Ethernet Parameters (Settings Tab)
Configuration Mode: This is fixed as TCP/IP.
Adapter Name: This is automatically generated based upon the rack/slot location of the Ethernet interface.
Use BOOTP for IP Address: This selection specifies whether the Ethernet must obtain its working IP address
over the network via BOOTP. When set to False (= do not use BOOTP), the IP Address value must be configured
(see IP Address parameter, below). When set to True, the IP Address parameter is forced to 0.0.0.0 and becomes
non-editable.
Note: The IP Address, Subnet Mask and Gateway IP Address must all be set to 0.0.0.0 in order to
use BOOTP to obtain the IP address.
IP Addresses: These values should be assigned by the person in charge of your network (the network
administrator). TCP/IP network administrators are familiar with these parameters. It is important that these
parameters are correct, otherwise the Ethernet Interface may be unable to communicate on the network
and/or network operation may be corrupted. It is especially important that each node on the network is
assigned a
unique
IP address.
If you have no network administrator and are using a simple
isolated network
with no gateways, you can use
the following range of values for the assignment of local IP addresses:
10.0.0.1 First Ethernet interface
10.0.0.2 Second Ethernet interface
10.0.0.3 Third Ethernet interface
. .
. .
. .
10.0.0.255 Programmer TCP or host
Also, in this case, set the subnet mask to 255.0.0.0 and the gateway IP address to 0.0.0.0.
Note: If the isolated network is connected to another network, the IP addresses 10.0.0.1 through
10.0.0.255 must not be used and the subnet mask, and gateway IP address must be
assigned by the network administrator. The IP addresses must be assigned so that they
are compatible with the connected network.
Name Server IP Address: : This parameter must be set to 0.0.0.0
Max Web Server Connections: (Available only when the Ethernet Interface supports web server operation.) The
maximum number of web server connections. This value corresponds to the number of TCP connections
allocated for use by the web server, rather than the number of web clients. Valid range is 0 through 16. Default
is 2.
Max FTP Server Connections: This value corresponds to the number of TCP connections allocated for use by
the FTP server, rather than the number of FTP clients. Each FTP client uses two TCP connections when an FTP
connection is established. Valid range is 0 through 16. Default is 2.
Note: The sum of Max Web Server Connections and Max FTP Server Connections must not
exceed 16 total connections.
Network Time Sync: Selection of the method used to synchronize the real-time clocks over the network. The
choices are None (for no network time synchronization) and SNTP (for synchronization to remote SNTP servers
on the network).
If None is selected, the time stamp value for a consumed EGD exchange is obtained from the local clock of the
producing Controller or PLC. Time stamps of exchanges produced by a PLC with this setting are not
synchronized with the time stamps of exchanges produced by other PLCs.
See “Time-stamping of Ethernet Global Data Exchanges” in Chapter 5 for more information.
Status Address: The Status Address is the reference memory location for the Ethernet Interface status data.
The Ethernet Interface will automatically maintain 16 LAN Interface Status (LIS) bits in this location and 64
Channel Status bits in this location for a total of 80 bits. The Status address can be assigned to valid %I, %Q,
