UICK

This Quick Start Guide provides a concise series of steps to get a pair of the NCB-Etherlon or NCB-Fiberlon modules “up and running” quickly so that initial operation may be confirmed.

It is highly recommended that a pair of NCB-Etherlon or NCB-Fiberlon modules be tested in your application by first connecting them “back-to-back” with the 10BaseT or fiber crossover cable included with this shipment. Once operation is confirmed using this connection scheme, continue by reconfiguring the IP addressing information and connecting the NCB modules to the actual Ethernet communications channel to be used.

TART GUIDE

-S

NOTE: DO NOT connect the NCB-Etherlon or NCB-Fiberlon modules to a live IP network until they have been reconfigured with new IP addresses and subnet mask supplied by the network manager. Network-wide problems could arise from connecting devices to a network without coordination of addressing information. See the Installation section of this manual for full information.

The Network Combiner NCBTM Module is a device that, when used in pairs, allows multiple

ONWORKS

networks to be connected in real-time, spanning distances from building-wide to worldwide. The communication channel spanning the distance between local networks can be any copper or fiber Ethernet

Read this section to learn the general function and capabilities of an NCB Router

channel that is capable of carrying IP (Internet Protocol) data. Data transfer between distant networks via NCB modules is "live", delayed only by the transit time through the routers and Ethernet channel.

The NCB module uses router technology so that no custom coding or additional hardware is necessary to seamlessly connect multiple networks across very large distances. The NCB module is self-contained, easily configured with standard network management tools, and requires no custom programming or coding changes in system nodes.

Both the NCB-Etherlon and the NCB-Fiberlon utilize the IP protocol over an Ethernet media and both can coexist on a wide-area IP network with other IP devices such as workstations, servers, and IP routers. Additionally, they can exist on

dedicated

Ethernet IP networks, where the only devices on the network are NCBs and (optionally) physical layer hubs. The most common occurrence of a dedicated network is a set of NCB-Fiberlons connected with dedicated fiber.

Basic Application

A basic application of the NCB module is where two multi-node beyond the reach of conventional wired media, need to be interconnected, as in Figure 1. This distance could be across a large building, business campus, city, etc. Using the NCB module, this interconnection is accomplished using one NCB module local to each network site and an Ethernet channel connecting the NCB modules. Additional networks can be added to this unified network by simply adding an NCB module for each network.

There are three sources of message packets within the NCB module. The first source is the

connector on the front of the unit. The second is the Ethernet media connectors on the rear of the unit. (Note that although 10BaseT and AUI connectors exist, only one can be used at a time.) The third source is the Control Neuron Processor. Message packets originating from any of these sources are sent to the other two. This message packet flow is shown in the block diagram of Figure 2.

example, an FTT-10A network, a TPT/XF-78 network, and a PLT-22 network can all be interconnected by using NCB modules with network transceivers matching the local network at each site.

NCB units are available with an option for

network transceiver options are available: A = FTT-10A K = SMX RS485 B = TPT/XF-78 M = SMX PL22 C = TPT/XF-1250 X = None (SMX ready)

Router Function

The router contained in each NCB module may be configured as a repeater, bridge, or configured router. The easiest configuration is as a repeater, where all messages which enter the NCB module (via any of the three data sources described above) are simply passed to the other two sources, regardless of the domain, subnet/node, or group destination address. A bridge forwards only messages that match one of the two domain IDs configured on the router. A configured router forwards only messages that match a domain ID as well as a set of subnet or group numbers. The proper choice of router mode depends on desired simplicity of installation versus required system performance.

Control Neuron Processor

The Control Neuron Processor provides access to IP address parameters. Ethernet channel parameters can be configured and displayed using the EtherPlug program. The Control Neuron Processor acts as another

ONWORKS

node on the network. It is connected to Side A of the router module, and appears to be located on

the Ethernet channel.

ONWORKS

system.

NOTE : DO NOT connect the NCB-Etherlon or NCB-Fiberlon modules to a live IP network until they have been reconfigured with new IP addresses and subnet mask supplied by the network manager. Network-wide problems could arise from connecting devices to a network without coordination of addressing information. For usage with dedicated fiber segments, see the note below.

Overall Installation Functions

Installation of an NCB-Etherlon or NCB-Fiberlon into an IP network that is shared by other IP devices (such as workstations, servers, etc.) requires performing the following three overall functions (not necessarily in this exact order) :

A. Configure the IP address parameters for each NCB B. Physically install each NCB into the system C. Commission each NCB using a

Installation of an NCB-Fiberlon into a system using requires performing only functions B and C above, as the default factory programmed IP address parameters can be used.

Configuration steps for function A above are performed by using the EtherPlug configuration software supplied with the NCB units. EtherPlug is a Windows program that can use a serial COM port and/or the network to configure the IP address parameters for each NCB. EtherPlug can be used as an LNS Plugin with programs such as LonMaker for Windows, or in a standalone mode requiring only Windows and a serial COM port. In preparation for function 1 above (not required for NCB-Fiberlons using dedicated fiber segments), basic IP addressing concepts must be understood. Appendix F of this manual provides a good overview. After determining which IP addressing mode will be used (Unicast/Replicated or Multicast), the following IP information must be gathered IP network to which the NCB units will be attached :

Restoring Factory Default Communication Parameters

If the Control Neuron Processor or router module communication parameters are overwritten by a network management tool, they can be restored as follows:

•

Press the “RESET” button on the front of the NCB unit

•

After the “ERR” LED goes off, press the “RESET” button a second time.

The Control Neuron communication parameters are now restored to factory defaults.

IP Address Parameters

The units are factory programmed as follows:

Further details of router operation and configuration are contained in the Echelon document entitled

ONWORKS

Router User's Guide", Echelon part number 078-0018-01B.

Address Assignments

The router inside the NCB module contains two Neuron chips, each with its’ own subnet/node number assignment. The default factory configuration of the router Neurons is subnet 255 node 126 and subnet 255 node 127. If any other nodes in the system to which the NCB is connected are configured with either of these subnet/node addresses, the router should be reconfigured to different addresses using any standard network management tool. The Control Neuron processor default address setting is subnet 255 node 1.

Buffer Configuration

The NCB module utilizes buffers to store incoming messages and route them out to other ports. The configuration of these buffers (the number of bytes in each buffer as well as the number of buffers) determine the maximum size message that can be passed and the performance of the NCB module under conditions of bursty traffic. In the standard configuration, the NCB router restricts the maximum size message that can be passed to a length of 40 to 50 bytes of user data, depending on the addressing overhead in the packet.

Technical Note TN010 discusses the topic of buffers and buffer sizes in detail, and should be referenced if messages to be passed through the NCB module could exceed the maximum default size.

These 32-bit addresses are commonly written because each decimal number represents 8 bits) separated by decimal points. Each octet can be a number from 1 to 255. For example, 131.9.1.2 is a valid IP address. The IP address assigned to a network device is commonly called the stations (also called hosts or nodes) on the network.

IP Address Classes

There are five types of IP addresses. Three are associated with networks – Class A, B, and C.

on a single IP network. The first octet is between 1 and 126. (127 is reserved for loopback and is used for internal testing on the local machine.)

• Class B

• Class C

Class D

•

• Class E

An IP address consists of two parts – one part identifies the network, and one part identifies the host (or node). The NetID portion of the IP address identifies the physical network segment. The HostID portion of the IP address identifies the node within the network segment. The following table lists the capacities of each IP address and the bits used as NetID and HostID.

addresses are for networks that have a large number of hosts, up to a maximum of 16,777,216

addresses are for medium-sized networks. The first octet is between 128 and 191. addresses are for small networks, up to 255 hosts. The first octet is between 192 and 223. addresses are reserved for multicasting and the first octet is between 224 and 239.

Subnetting using Subnet Masks

A portion of the host bits can be used to “subnet the network”. The subnet mask identifies the “NetID” and “HostID” portions of the IP address in a bitwise fashion. The mask is constructed by placing a “1” in any bit that is part of a subnetwork address. So subnet mask bits that are SET define the NetID, and CLEARED subnet mask bits define the HostID.

A subnet mask of 255.255.255.0 defines the NetID as the first three octets, and the HostID as the last octet. For example, for the address 192.47.73.111 and the subnet mask of 255.255.255.0, the subnetwork can be identified as 192.47.73.0.

Summary of Important Networking Details

•

A specific “NetID” can exist on only ONE port of ONE IP router.

•

The “NetID” portion of the Host Address and the Gateway Address MUST BE THE SAME.

•

If a functional router (such as a NCB Router) is moved to a different location, its Host IP Address and Default Gateway IP Address MUST BE CHANGED to match the “NetID” at the new location.

MAC Addresses

Whereas IP uses Logical Addresses to identify a host (node), other protocols use Hardware Addresses called Media Access Control addresses, or MAC addresses. MAC addresses are set at the factory at time of manufacture and cannot be changed. (IP addresses can be changed at any time.) A MAC address consists of six octets, in hexadecimal notation, separated by colons. An example would be: 00:10:EE:00:02:34.

The first three octets in a MAC address identify the manufacturer. In the above example, 00:10:EE identifies CTI Products as the manufacturer of this device. The last three octets are sequentially assigned by the manufacturer to form a type of serial number. In this way, no two devices have the same MAC address.

Multicast addressing is also possible using MAC addresses, just as in IP addressing. MAC addresses reserved for broadcast messages start at: 00:01:5E:00:00:00.

Address Resolution Protocol (ARP)

Since IP uses Logical Addresses at the OSI Network Layer (Layer 3) and Ethernet uses MAC addresses at the OSI Data Link Layer (Layer 2), Address Resolution Protocol is used whenever IP is used over the Ethernet. ARP is needed to convert an IP address to a MAC address. The client then stores this resolved address for a period of time in its ARP cache. An ARP cache is a lookup table, typically in a router, that will store a quantity of resolved addresses for devices that it must communicate with.

Appendix F. IP Addresses 34

CTI Products, Inc. NCB-EL/FL User Guide

When a message is destined for an IP address whose MAC address has not yet been resolved, an ARP REQUEST is sent from the local host as a broadcast message, asking for MAC identification. A remote host with the IP address in question generates an ARP RESPONSE. This ARP RESPONSE contains the requested MAC address. The local host receives the message, and places the IP Address and the matching MAC Address in its ARP Cache. The original message is then sent using the MAC Address found previously. Any additional messages to this remote IP address will be sent using the MAC address found in the local host’s ARP cache.

Ethernet 10BaseT Cables

When connecting two IP devices together, either a straight-through cable or a crossover cable may be required.

If interconnecting similar devices, then a crossover cable is needed. Examples would be interconnecting two NCB routers, or two IP routers, or two hubs, or two computers. Generally, if the two devices are both Layer 3 devices, then a crossover cable is required. Routers operate at Layer 3. Similarly, if the two devices are Layer 1 or 2 devices, they would also require a crossover cable. Bridges, switches, and Network Interface Cards (NIC) operate at Layer 2, and hubs, repeaters, and concentrators operate at Layer 1.

If interconnecting dissimilar devices, then a straight-through cable is needed. Dissimilar devices would involve one Layer 3 device and a Layer 1 or Layer 2 device.

The following table summarizes devices in each layer.
