Section 2-1 Communications Functions 2-1-1 Ethernet Unit Functions Function Contents FINS communications • A SEND(090), RECV(098), or CMND(490) instruction from the PC’s ladder program is used to send a FINS command to a remote node, and a response is received. • A FINS command is received from a remote node. If the command is addressed to the local Unit, it is processed internally.
Section 2-2 FINS Communications 2-1-3 Selecting Communications Services Refer to the following guidelines to select the appropriate communications service to use in a given situation. To communicate with an OMRON PC. To communicate with a host computer (with the FINS gateway function enabled). FINS Communications To perform operations with an OMRON PC other than sending or receiving data (for example, reading or writing files or changing the operating mode). Refer to Section 5 FINS Communications.
Section 2-3 Socket Services CMND(490) instructions in the ladder-diagram program. This enables control operations such as the reading and writing of I/O memory between PCs, mode changes, and file memory operations. (When a FINS message is sent on an Ethernet network, a UDP/IP header is automatically added to the message.) The FINS gateway function allows access not only to PCs on the same Ethernet network, but also to PCs on other networks such as SYSMAC LINK or Controller Link.
Section 2-3 Socket Services There is no need to execute the CMND(490) instruction or to monitor the completion 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 services. UNIX computer, etc.

SECTION 5 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.
Section 5-1 Overview of FINS Communications 5-1 Overview of FINS Communications The FINS communications service enables client control of operations such as reading or writing server PC memory area data without the need to program these operations into the server PC user program. The Ethernet Unit uses a dedicated UDP/IP port to execute the FINS communications service. (Refer to FINS UDP Port Number under 4-2-1 Settings.
Section 5-1 Overview of FINS Communications • Writing data, changing modes, reading detailed information about Units, and so on, can be executed without any particular knowledge of communications procedures or network classification. • Units and Boards that support FINS commands return responses automatically, 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.
Section 5-2 Procedure Before Using FINS Communications 5-2 Procedure Before Using FINS Communications Start Determine the address conversion method for the destination IP address. IP Address Table Converted from table of correspondences between FINS node numbers and IP addresses. Automatic Generation Automatically converted from FINS node number. Select the IP table address method for the address conversion method in the System Setup, and create an IP address table.
Section 5-3 Sending Commands From a PC 5-3 Sending Commands From a PC FINS commands can be sent from the user’s ladder-diagram program in the PC by using the SEND(090), RECV(098), and CMND(490) instructions. SEND(090): Writes I/O data from the local node to another node. RECV(098): Reads I/O data from another node to the local node.
Section 5-3 Sending Commands From a PC Using SEND(090), RECV(098), and CMND(490) Make the settings shown below when using the SEND(090), RECV(098), and CMND(490) instructions in the user’s ladder-diagram program in the PC. The SEND(090) instruction sends the data in n number of words, starting from the beginning word S at the local node, to the words starting from the beginning word D at the remote destination node (node number N).
Section 5-3 Sending Commands From a PC With the RECV(098) instruction, the data in m number of words, starting from the beginning word S at the remote node (node number M) is received at the words starting from the beginning word D at the local node.
Section 5-3 Sending Commands From a PC CMND(049) The CMND(049) instruction sends n bytes of command data, starting from the beginning word S at the local node, to the node at node number N. the data in m number of words, starting from the beginning word S at the remote node (node number M) is received at the words starting from the beginning word D at the local node.
Section 5-3 Sending Commands From a PC Commands Addressed to CS/CJ-series CPU Units The following table provides a list of FINS commands that can be processed by a CS/CJ-series CPU Unit. For details, refer to the CS/CJ-series Programmable Controllers Communications Commands Reference Manual (W342). For details on FINS commands that can be processed by the Ethernet Unit, refer to Section 11 FINS Commands Addressed to Ethernet Units.
Section 5-3 Sending Commands From a PC Usage File memory Debugging 88 Command code MR SR Name Function 22 22 01 02 FILE NAME READ SINGLE FILE READ Reads file memory data. Reads a specified length of file data from a specified position within a single file. 22 03 SINGLE FILE WRITE Writes a specified length of file data from a specified position within a single file. 22 22 04 05 FILE MEMORY FORMAT FILE DELETE 22 07 FILE COPY Formats (initializes) the file memory.
Section 5-3 Sending Commands From a PC Writing Programs Programs incorporating the SEND(090), RECV(098), and CMND(490) instructions are generally created using the Communications Port Enabled Flag and the Communications Port Error Flag as input conditions. CS/CJseries CPU Units have eight communications ports. Only one instruction can be executed at any given port at one time, however, so the program must not overlap the use of any of the ports. A program example is provided below.
Section 5-3 Sending Commands From a PC Communications Flags The execution status of the SEND(090), RECV(098), and CMND(490) instructions is always reflected by the communications flags (i.e., the Communications Port Enabled Flag and the Communications Port Error Flag). The CS/ CJ-series CPU Unit’s communications flags are allocated in the Auxiliary Area as shown in the following table.
Section 5-3 Sending Commands From a PC Communications Port Error Flag and Completion Codes CMND(490) Errors that occur when CMND(490) is used generate a Communications Port Error Flag and are recorded in a communications port completion code only in the following cases: • When a response timeout error has occurred. • When the number of communications data bytes exceeds the maximum value for the Unit (i.e., 2,000 bytes for the Ethernet Unit).

Section 6-1 Overview 6-1 6-1-1 Overview Socket Service Functions The socket services allow devices on the Ethernet to send and receive various 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.
Section 6-1 Overview Specific Socket Service Functions The socket service functions listed in the following table can be executed either using Socket Service Request Switches or using CMND(490).
Section 6-1 Overview quently, port numbers 1024 and above should be used for socket services. The Ethernet Unit does not support port #0. Some port numbers over 1024 may be reserved on some workstations (for example, the X-window server is port #6000). Do not use port numbers that are already reserved for other processes. The setting status of the UNIX workstation port numbers can be checked in / etc/services.
Section 6-1 Overview 6-1-6 Opening TCP Sockets To achieve highly reliable data communications, TCP establishes a virtual communications circuit between the two nodes before starting data transmissions. The virtual communications circuit is known as a “connection.” Passive OPEN and Active OPEN Client TCP socket An open command is executed for a node to establish a connection. The open method differs depending on whether the node is a client or server.

Using Socket Services with Socket Service Request Switches Section 6-2 • Data can remain in a buffer at the local node if the remote TCP socket closes during communications. Any data remaining in the buffer will be discarded when the TCP socket is closed. To avoid problems of this nature, steps will have to be taken in the application program, such as sending data to enable closing, and then only closing once reception of this data has been confirmed.

Appendix A Network Installation Basic Installation Precautions • Take the greatest care when installing the Ethernet System, being sure to follow ISO 8802-3 specifications. You must obtain a copy of these specifications and be sure you understand them before attempting to install an Ethernet System. Unless you are already experienced in installing communications systems, we strongly recommend that you employ a professional to install your system. • Do not install Ethernet equipment near sources of noise.
Network Installation Appendix A • Ground the external shield of the coaxial cable to 100 W or less using AWG 14 wire (cross-sectional area of 2 mm2) or better and a ground cable length of 20 m or less. Ground each segment of the network at one location only. Do not use the same ground for other equipment. • The physical properties (e.g., minimum bending radius) of coaxial cable vary with the manufacturer. Follow all recommendations and specifications of the manufacturer.
