SECTION 5 FINS Communications This section provides information on communicating on Ethernet Systems and interconnected networks using FINS com- mands. 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 74: 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 75: Overview Of Fins Communications
• Units and Boards that support FINS commands return responses automatical- ly, 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 correctly setting information such as headers, however, it can also be used from ordinary Ether- net communications devices.

Overview Section 6-1-7 Fragmentation of Send Data The Ethernet Unit fragments data for TCP transmission into units of 1,024 bytes and data for UDP transmission into units of 1,472 bytes. TCP requires one reception request to receive each unit of data. UDP, however, restores the origi- nal data before passing it to the user process, allowing all the data in a single transmission to be received with one reception request.
Page 103 Overview Section 4. When the receiving user program sends a request to receive 1,984 bytes of data, Data A and Data B are linked to restore the original data, which is passed to the user program. Sending User Program Ethernet Unit Receiving Node Receiving User Program 1.
Page 104: Maximum Transmission Delays
Overview Section 6-1-8 Maximum Transmission Delays The transmission delays for socket service is calculated as the sum of the com- munications processing times for both nodes. Transmission delay = Remote node send processing time + Local node re- ceive processing time + Local node send processing time + Remote node receive processing time Calculate the maximum Ethernet Unit transmission delays for sending and re- ceiving using the following formulas.
Page 105 Overview Section • The socket status area in the CIO Area is zeroed when the PC’s operating mode is changed (e.g., from PROGRAM to RUN). The actual Ethernet Unit socket status, however, will remain unchanged after the socket status area is zeroed.
Page 106: Using Socket Services With Socket Service Request Switches
Using Socket Services with Socket Service Request Switches Section • The Ethernet Unit TCP sockets have no KEEP ALIVE function to check that the connection is normal if communications do not occur for a set time period through a communications line for which a connection has been established. The Ethernet Unit’s TCP sockets make no checks to the socket at the other node.

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 256: 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.
