Configuration Mode
IP Address, Subnet Mask,
and Gateway IP Address
Status Address
Ethernet Configuration
For public disclosure
The CPU's fundamental Ethernet operating characteristics must be correctly configured
for proper operation over an Ethernet network. The default configuration cannot supply
valid network address data.
This is fixed as TCP/IP. It cannot be changed.
The IP Address is the unique address of the Ethernet interface as a
node on the network. On a large network, a subnet mask can be
used to identify a section of the overall network. A gateway address
can be used to identify a gateway that joins one network with
another.
These parameters must be correct or the Ethernet interface may be
unable to communicate on the network and/or network operation
may be disrupted. It is especially important that each node on the
network is assigned a unique 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. If you have no network
administrator and are using a simple isolated network with no
gateways, you can use the following values as local IP addresses:
10.0.0.2 First PLC
10.0.0.3 Second PLC
10.0.0.4 Third PLC
. .
10.0.0.254 PLC Programmer or host
Also, in this case, set the subnet mask and Gateway IP address to
0.0.0.0.
See chapter 13 for more detailed information about IP Addressing
and gateways.
Note: If this simple, isolated network is ever connected to another
network, the IP addresses 10.0.0.2 through 10.0.0.254 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.
The beginning reference for 10 bytes of Ethernet status data. The
content of this data is described in chapter 13,
of the Ethernet Interface.
The Status address can be assigned to %I, %Q, %R, %AI or %AQ
memory. The default value is the next available %I address.
Note: Do not use the 10 bytes assigned to the Status bits for other
purposes or your data will be overwritten.
