Status Length:
This is the sum of the LIS bits and the Channel Status bits. This value is
automatically set to either 80 bits (for %I and %Q Status address locations) or 5 words (for %R,
%AI, and %AQ Status address locations).
IP Address, Subnet Mask, Gateway IP Address, and Name Server IP Address:
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.
However, 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 PLC
10.0.0.2
Second PLC
10.0.0.3
Third PLC

.
10.0.0.255
PLC Programmer TCP or host
Also, in this case, set the subnet mask, gateway IP address, and name server IP address to 0.0.0.0.
Note
If the isolated network is ever connected to another network, the IP addresses
10.0.0.1 through 10.0.0.255 must not be used and the subnet mask, gateway IP
address, and name server IP address must be assigned by the network
administrator. The IP addresses must be assigned so that they are compatible
with the connected network. Refer to Chapter 6, “Network Administration
Support”, for more information on addressing.
See also “Determining If an IP Address Has Already Been Used” in this
section.
Network Time Sync:
Selection of the method used to synchronize the real-time clocks over the
network. Currently the choices are None/DISABLED (for no network time synchronization) and
SNTP/ENABLED (for synchronization to remote SNTP servers on the network).
AAUI Transceiver Power (Watts):
Allows you to account for the power consumption added by
the AAUI Transceiver attached to the Ethernet module (measured in Watts). The valid range is
0.0 to 2.00. The default value is 0.0.
