4. In the Module Catalog dialog box, click the Communications tab, select
IC693CMM321 Ethernet Interface, then click the OK button. The Parameters dialog
box will appear:
5. This dialog box will allow you to edit the module’s parameters. To edit a parameter
value, click in the appropriate Values field. The details of the Settings tab are as
follows:
l
Configuration Mode: This is currently fixed as TWII?
l
Status Reference Type: 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 default 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.
l
Status Length: This is fixed at 80 bits (the sum of the LIS bits and the Channel
Status bits).
l
IP Address, Subnet Mask, Gateway IP Address, and Name Server IP Address:
The values for the II’ Address, Subnet Mask, and Gateway Address 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 II’ 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 II’ addresses:
