The IP information that was gathered from the IP Network Administrator, as described at the beginning of
section 2 of this manual, must be entered into the EtherPlug program as follows:
A) Specify the Channel Global IP Parameters:
• After reviewing the information concerning IP Addressing Modes in Appendix F, choose either
“Unicast/Replicated” or “Multicast” from the “IP Address Mode” drop-down list.
• If “Multicast” was selected above, enter the Multicast IP Address that the IP Network
Administrator has assigned to this group of NCBs.
• Click on the “Global IP Subnet Mask” textbox, then enter the Subnet Mask assigned the the
NCB units by the IP Network Administrator.
• If different subnet masks are specified for different groups of NCB units, enter the subnet mask
that is common to most of the NCB units in the group.
• If a different subnet mask is assigned to every NCB unit, leave this field with its default value.
B) Specify the “Channel Member List” parameters:
If EtherPlug was launched as an LNS Plug-in, the names of all Control Neuron Processors attached to the
custom Ethernet channel will already be listed in the Channel Member List.
If EtherPlug was launched as a standalone program, use the Add New Member button to add a line in the
Channel Member List and enter the name for each NCB unit connected to the custom Ethernet channel.
Enter the following information for each NCB unit in the Channel Member List :
• Host IP Address
• IP Subnet Mask (if different than the “Global IP Subnet Mask”). With IP Subnet Mask set to
GLOBAL, the value set in the Global IP Subnet Mask field is used as this member’s IP Subnet
Mask
• Gateway IP Address
• Leave the Targets field set to All in Channel unless Central Site mode is to be used, see the bullet
below for a description of this mode.
• Leave the MAC Refresh field to Disabled unless the NCB is connected to an Ethernet MAC layer
switch or intelligent hub. See the bullet below for further information.
Several special cases should be considered, as discussed below:
• Central Site Mode: If Unicast/Replicated IP Addressing mode is being used and the system
application using these NCB units requires L ON W ORKS messages to pass only between devices
connected to a single NCB unit at the host computer and devices connected to NCB units at remote
locations, Central Site mode can be used to reduce network traffic. To restate, if the system being
constructed does not require
L ON W ORKS messages to flow between devices at different remote
sites, but only between a remote site and a single central site, use Central Site mode. If
L
ON W ORKS messages must flow between remote sites and the Central site and also from one
remote site to another remote site, do not use Central Site mode.
To use Central Site mode :
• Set IP Central Site Member Name to the name of the NCB unit with its NETWORK
port connected to the L ON W ORKS network from the Host Computer. This must be the
same computer on which the network management software is being run.
