Page 20 PRECAUTIONS This section provides general precautions for using the CS1W-ETN21 and CJ1W-ETN21 Ethernet Units (100Base-TX). The information contained in this section is important for the safe and reliable application of Ethernet Units. You must read this section and understand the information contained before attempting to set up or operate an Ethernet Unit.
Page 21: Intended Audience
It is extremely important that a PLC and all PLC Units be used for the speci- fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC System to the above-mentioned appli- cations.
Page 22: Operating Environment Precautions
Operating Environment Precautions • Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits. !Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the torque specified in the operation manual. The loose screws may result in burning or malfunction.
Page 23 Application Precautions • Always turn OFF the power supply to the CPU Unit, Slaves, and Commu- nications Units before attempting any of the following. Not turning OFF the power supply may result in malfunction or electric shock. • Mounting or dismounting I/O Units, CPU Units, Memory Packs, or Master Units.

Use the UDP/IP version of the FINS communications service (i.e., FINS/ Same Segment UDP). FINS/UDP is supported by many OMRON products and is compatible with earlier Ethernet Units (CS1W-ETN01/ETN11 and CJ1W-ETN11). The CX-Programmer can be connected and used with FINS/UDP even if personal computer middleware (FinsGateway) is not used.
Page 28 Section 1-1 Ethernet Unit Function Guide Connecting through Use the TCP/IP version of the FINS communications service (i.e., FINS/TCP). Multiple Segments FINS/TCP is a new function supported by these Ethernet Units (CS1W- ETN21 and CJ1W-ETN21). It provides automatic recovery at the TCP/IP layer from communications errors (such as packet loss) that occur during multilevel routing.
Page 29 UDP), and construct applications using the SEND(090), RECV(098), and CMND(490) instructions in the ladder program. FINS/UDP is supported by many OMRON products, and is compatible with earlier Ethernet Units (CS1W- ETN01/ETN11 and CJ1W-ETN11). The protocol processing for FINS/UDP is simpler than for FINS/TCP, giving FINS/UDP certain advantages in terms of performance.

Ethernet network. The protocols that can be selected include sending and receiving data by TCP/IP or UDP/IP (socket services), sending and receiving commands by OMRON's standard protocol FINS, transferring files by FTP, sending and receiving e-mail by SMTP/POP3, and automatically adjusting the PLC's internal clock by SNTP.
Page 34 Section 1-2 Features Starting with unit version 1.5, the performance of sending and receiving has been improved using optional settings for the TCP or UDP socket services using specific bits in memory. Also, a linger socket option has been added to the TCP socket services.
Page 35 Section 1-2 Features • The Ethernet Unit can automatically generate data files (6,000 words maximum per file) from the CPU Unit's I/O memory status, and send them to specified e-mail addresses as e-mail attachments.

Page 42: Overview Of Communications Functions
Overview of Communications Functions Section 1-5 Overview of Communications Functions 1-5-1 FINS Communications Service Basic Functions FINS commands can be sent to or received from other PLCs or computers on the same Ethernet network by executing SEND(090), RECV(098), or CMND(490) instructions in the ladder diagram program. This enables various control operations such as the reading and writing of I/O memory between PLCs, mode changes, and file memory operations.
Page 43: Socket Services
Section 1-5 Overview of Communications Functions • Even if the IP address and UDP port number of the host computer (a DHCP client computer) are changed, it is still possible for the host com- puter to send FINS commands to PLCs on the Ethernet network and to receive responses.
Page 44 Section 1-5 Overview of Communications Functions Executing CMND(490) Another way to use socket services is to request a UDP or TCP socket ser- vice by sending a FINS command to the Ethernet Unit by executing CMND(490) from the CPU Unit. When the Ethernet Unit receives the socket service request, it returns a response to the CPU Unit to confirm that it received the request, and then begins the requested processing.
Page 45: Ftp Server Function
Section 1-5 Overview of Communications Functions 1-5-3 FTP Server Function The Ethernet Unit has a built-in FTP server, so other computers on the Ether- net can read or write individual files on 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 PLC, with the host computer functioning as an FTP client and the PLC as an FTP server.

Because CIDR does not use a class, it is possible to divide the IP address space as desired, which enables efficient use of IP address space (i.e., number of hosts).

Page 141: Overview Of Fins Communications
Ethernet Address The FINS communications service is a communications method based on UDP/IP, and it is supported by most OMRON Ethernet-related products. (In this manual it is called the FINS/UDP method.) In addition to supporting the FINS/UDP method, the CS1W-ETN21 and CJ1W-ETN21 support FINS com- munications using TCP/IP.
Page 142: Fins Communications Service Specifications For Ethernet
Overview of FINS Communications Section 6-1 • When FINS nodes are connected on the same Ethernet segment: Use the FINS/UDP method between those nodes. Note FINS/UDP offers a slight advantage in performance. • When FINS nodes are connected over multiple IP network layers: Use the FINS/TCP method between those nodes.
Page 143: Fins/Udp Method
Section 6-2 FINS/UDP Method FINS/UDP Method 6-2-1 Overview FINS/UDP Features The FINS/UDP method is a FINS communications method that uses the UDP/ IP protocol. UDP/IP is a connectionless communications protocol. When a message is sent from one node to another, the two nodes have an equal rela- tionship and there is no clear connection.
Page 144 Section 6-2 FINS/UDP Method UDP Port Numbers for The UDP port number is the number for UDP to identify the application layer FINS/UDP (i.e., the FINS communications service in this case). When communications are executed by UDP/IP, this port number must be allocated to the communi- cations service.
Page 145: Fins/Tcp Method
Section 6-3 FINS/TCP Method FINS/TCP Method 6-3-1 Overview FINS/TCP Features The FINS/TCP method is a FINS communications method that uses the TCP/ IP protocol. TCP/IP is a connection-type communications protocol. Before a message is sent from one node to another, it is necessary to establish a vir- tual circuit, i.e., a connection.
Page 146 FINS/TCP Method Section 6-3 • Once a FINS/TCP connection (connection number, remote IP address) has been set in the Unit Setup, it can be dynamically changed from the ladder program using a FINS command (i.e., FINS/TCP CONNECTION REMOTE NODE CHANGE REQUEST). FINS/TCP Frame Format The following diagram shows the structure of a TCP packet sent over an Ethernet network.
Page 147 FINS/TCP Method Section 6-3 FINS/TCP Connection Status (Word n+23) While a connection with a remote node is established, the bit corresponding to the FINS/TCP connection status turns ON in the section of the CPU Bus Unit words allocated in the CIO Area. The bit turns OFF if the connection is termi- nated by a communications error or a FINS command (i.e., FINS/TCP CON- NECTION REMOTE NODE CHANGE REQUEST).
Page 148 Section 6-3 FINS/TCP Method Even if the connection is closed at the FINS/TCP client, requests continue to be made to the FINS/TCP server every few seconds to open a connection. Note After the Ethernet Unit is powered up or restarted, the IP address for the con- nection used as the FINS/TCP client is the remote IP address set under the FINS/TCP Tab in the Unit Setup.
