CPU374 Configuration Parameters
Ethernet Parameters
Configuration Mode:
This is fixed as TCP/IP.
Adapter Name:
This field is set to 0.1 (the rack and slot of the Ethernet Interface) and cannot be
changed.
Status Address:
The Status Reference Type is the location of the LAN Interface Status (LIS)
bits (16 bits) and the Channel Status bits (64 bits). The Channel Status bits are always located
immediately following the LAN Interface Status bits. 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 80-bits assigned to the LIS bits and Channel Status bits for other
purposes or your data will be overwritten.
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, and Gateway 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
