Page 22: Features And System Configuration
This section introduces the overall structure of an Ethernet network, outlines the features of the Ethernet Unit, describes the communications protocols used by an Ethernet network, and provides basic precautions for use of an Ethernet network. Features ............System Configuration .
Page 23: Features
The Ethernet Unit also supports FINS message communications, OMRON’s standard communications service, so other OMRON PCs can be accessed by using SEND(090), RECV(098), and CMND(490) instructions in ladder pro- grams. In addition, the FINS gateway function can be used to allow access to other PCs on not only the same Ethernet network but also on other networks such as Controller Link and SYSMAC Link.

Page 41 Socket Services By Executing CMND(490) There is no need to execute the CMND(490) instruction or to monitor the com- pletion timing and actual processing of the instruction, so this helps to simplify ladder programming. A total of eight ports (UDP and TCP combined) can be used for socket ser- vices.
Page 42: Ftp Server
FTP Server FTP Server Mail Note The Ethernet Unit has a built-in FTP server function, so other computers on the Ethernet can read or write individual files in a Memory Card mounted to the CPU Unit or in EM file memory. This allows files to be exchanged between the host computer and the PC, with the host computer functioning as an FTP client and the PC as an FTP server.

Page 100: Fins Communications
This section provides information on communicating on Ethernet Systems and interconnected networks using FINS commands. The information provided in the section deals only with FINS communications in reference to Ethernet Units. FINS commands issued from a PC are sent via the SEND(090), RECV(098), and CMND(490) instructions programmed into the user ladder-diagram program.
Page 101: Overview Of Fins Communications
The FINS communications service is a function for controlling operations such as sending and receiving data, changing modes, and so on, between nodes on OMRON factory automation networks. It provides the following features. • Communications instructions are executed in the user program.
Page 102 • Units and Boards that support FINS commands return responses auto- matically, so there is no need for a program at the receiving end. • The FINS communications service is mainly used between OMRON CPU Bus Units, CPU Units, and Support Boards for FA Computers. By cor- rectly setting information such as headers, however, it can also be used from ordinary Ethernet communications devices.
Page 103: Procedure Before Using Fins Communications
Procedure Before Using FINS Communications Procedure Before Using FINS Communications Start Determine the address conversion method for the destination IP address. Automatic Generation Automatically converted from FINS node number. Set the IP address (see note) so that the host number's least significant byte = the FINS node number.

Overview Overview 6-1-1 Socket Service Functions Note One of the main differences between using Socket Service Request Switches Using Socket Service Request Switches Note Using CMND(490) The socket services allow devices on the Ethernet to send and receive vari- ous data using the UDP or TCP protocol. The socket services can be used by CS/CJ-series PCs through the user program by manipulating dedicated bits (called Socket Service Request Switches) or by executing the CMND(490) instruction.

Page 128: Opening Tcp Sockets
Overview 6-1-6 Opening TCP Sockets Passive OPEN and Active OPEN Client socket Note TCP Communications Procedure To achieve highly reliable data communications, TCP establishes a virtual communications circuit between the two nodes before starting data transmis- sions. The virtual communications circuit is known as a “connection.” An open command is executed for a node to establish a connection.

Recommended Products The following products are recommended for use with the CS1W-ETN01 Ethernet Unit. CS1W-ETN01 (10Base-5) CS1W-ETN11, CJ1W-ETN11 (10Base-T) CS1W-ETN01 (10Base-5) Precautions Coaxial Cable Installation Precautions Basic Precautions • As a rule, always lay coaxial cables indoors. Laying coaxial cables outdoors requires special measures that should be performed only by a professional.
Page 273 Network Installation • Ground the external shield of the coaxial cable to 100 W or less using AWG 14 wire (cross-sectional area of 2 mm ) or better and a ground cable length of 20 m or less. Ground each segment of the network at one location only.

Page 275 Network Installation Ceiling Installation Examples Installation Examples for Noise-prone Environments Ethernet networks do not withstand noise very well and require special installation measures if installed where subject to noise. The remainder of this section describes measures for dealing with noise. Note Although the measures described in this section are suitable to certain levels of noise, programming retries in communications will still be required.

Distribution box Transceiver cable Noise Wooden board Transceiver 2. Metal box for transceiver Note 1. Cover all metal portions of cables with insulating tape to be sure they do not come into contact with the metal ducts or boxes.
Page 277 Network Installation Multipoint Transceivers Multipoint transceivers can be used to eliminate the need for coaxial cable (which is easily affected by noise) and replace it with transceiver cable as shown in the following diagram. This will increase overall system resis- tance to noise.
Page 278 Transceiver cable Repeater Note Consult with the manufacturer for details on optical Ethernet devices. CS1W-ETN11, CJ1W-ETN11 (10Base-T) Precautions Precautions on Laying Twisted-pair Cable Basic Precautions • Press the cable connector in firmly until it locks into place at both the hub and the Ethernet Unit.
Page 279 Network Installation Hub Connection Methods If more hub ports are required, they can be added by connecting more than one hub. There are two possible connection methods for hubs: Cascade and stacked. Cascade Connections • Connect two hubs to each other as follows: Connect an MDI port to an MDI-X port with a straight cable; connect two MDI ports with a cross cable;...
Page 280 Network Installation Cable Location Separate the transceiver cable or twisted-pair cable connecting the Ethernet Unit as far from the wiring to the Contact Output Units as possible. The coaxial cable must also be placed as far away from the Contact Output Units and their wiring as possible.

Page 285 Buffer Configuration Network Memory Most of the buffers used for communications servicing by the Ethernet Unit are administered in a buffer config- uration called network memory. Network memory consists of 196K bytes of memory divided into short and long buffers. The use of short and long buffers is determined by the status of the various services when the Ethernet Unit is running.

Page 304: Maintenance
The Ethernet Unit makes up part of a network. Repair a defective Ethernet Unit as soon as possible as it can have a negative effect on the entire network. We recommend that customers keep one or more spare Ethernet Units to allow immediate recovery of the network. Replacing an Ethernet Unit Observe the following precautions when replacing the Ethernet Unit.
Page 306: J Inspections
Carry out regular inspections to ensure the Ethernet Unit is functioning perfectly. Items Most of the parts that make up an Ethernet Unit are semiconductor components. None of the parts in the Unit will wear out after a specific lifetime, but some parts may deteriorate due to extreme operating condition. Therefore, it is important to inspect the Unit regularly.
