Page 33: Ip Addresses
IP Addresses Section 1-7 IP Addresses Ethernet networks use IP addresses for communications. IP addresses (Inter- net addresses) identify both the Ethernet network and the node (host com- puter, Ethernet Unit, etc.) on the Ethernet network. IP addresses must be set and controlled so that they are not duplicated.
Page 34: Ip Address Settings
IP Addresses Section 1-7 nodes regardless of the networks on which they exist. To achieve this, net- work numbers are allocated by the Network Solutions, InterNIC Registration Services, to ensure that all Ethernet networks have unique numbers regard- less of where they exist. The local system administrator is left the responsibil- ity of allocating unique host numbers locally.

Page 41 Socket Services Section 2-3 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 Section 2-4 FTP Server 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.

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.

Sending Commands From a PC Section 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.

SEND(090) 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 begin- ning word D at the remote destination node (node number N).

Page 110 Sending Commands From a PC Section 5-3 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/CJ- series 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.
Page 111 Sending Commands From a PC Section 5-3 Communications Flags The execution status of the SEND(090), RECV(098), and CMND(490) instruc- tions is always reflected by the communications flags (i.e., the Communica- tions 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.

Communications Testing Functions Section 9-1 Communications Testing Functions The Ethernet Unit provides two functions that allow communications with other node to be tested. PING Command The PING command is a common way to perform echoback tests on Ethernet networks. The PING command can be executed to see if nodes are physically connected properly and to be sure that IP address are set for the correct Ethernet nodes.

Internode Test Section 9-3 Method Input the following at the host computer prompt ($): ping IP_address(host_name) The destination is specified by its IP address or host name. If the host name is used, the host name must be defined in file /etc/hosts. Note The PING command is not supported by some host computers.

Page 304: Maintenance
Appendix I 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.
Page 306: J Inspections
Appendix 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.
