Page 183: Using Fins Communications To Create Host Applications
Using FINS Communications to Create Host Applications 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 PLC are sent via the SEND(090), RECV(098), and CMND(490) instructions programmed into the user ladder-diagram program.
Page 184: Overview Of Fins Communications
Physical Layer 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 186: Fins Frames
FINS Frames FINS Frames The FINS communications service is carried out through the exchange of FINS command frames and their corresponding response frames. (There are also commands with no responses.) Both command frames and response frames are comprised of a FINS header for storing transfer control information, a FINS command field for storing a command, and a FINS parameter/data field for storing command parameters and transmission/response data.

Page 195: Fins/Tcp Method
FINS/TCP Method FINS/TCP Method 7-4-1 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 196 FINS/TCP Method FINS/TCP Frame Format Ethernet V.2 TCP Port Number for FINS/TCP FINS/TCP Connection Numbers • 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).
Page 197: Communications Procedure
FINS/TCP Method FINS/TCP Connection While a connection with a remote node is established, the bit corresponding to Status (Word n+23) 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 an error in communications with a remote node or a FINS command (i.e., FINS/TCP CONNECTION REMOTE NODE CHANGE REQUEST).

Page 199 FINS/TCP Method ■ Setting Range for Automatic Allocation of FINS Node Addresses The range of node addresses that can be used as automatically allocated FINS node addresses is set in the Ethernet Unit’s Unit Setup. Normally (default status), node addresses 239 to 254 are allocated to each of the con- nections 1 to 16.

Page 202 FINS/TCP Method When automatically allocated FINS node addresses are set, the client node address automatically allocated at the server is stored in the client node address field. After a connection has been established as a FINS/TCP client or server, do not send this command again.
Page 203 FINS/TCP Method FINS/TCP header The details of the above frame are shown in the following table. FINS FRAME SEND If an error occurs in the FINS/TCP header of the FINS FRAME SEND com- ERROR NOTIFICATION mand, this command is used so that an error code will be returned to the node Command that sent the FINS FRAME SEND command by the node that detected the error.
Page 204: Connection Sequence
FINS/TCP Method After the command is sent, if ACK is returned in the TCP layer by the remote node, the connection that is established is maintained. If RST is returned in the TCP layer by the remote node, the established connection is closed.

Page 208: Sending Commands From A Host Computer
FINS/TCP Method From step 12 onwards, the connection is established again. Note When FINS node addresses are automatically allocated, the node address cannot be specified, so the connection remains open until it is closed by the keep-alive function. 7-4-3 Sending Commands from a Host Computer When sending FINS commands from a computer, the command data in the computer’s program must be created in command frame format.

Page 216: Maximum Transmission Delays: Writing/Reading To Cpu Unit
Maximum Transmission Delays: Writing/Reading to CPU Unit Maximum Transmission Delays: Writing/Reading to CPU Unit The time for the response to be received after a remote node on the Ethernet network sends a memory area read or write command to a PLC can be calcu- lated using the following formula.
Page 217 Maximum Transmission Delays: Writing/Reading to CPU Unit For details, refer to the CPU Unit operation manual. Transmission Processing 0.704 ms (Response) Note The actual operating environment can cause transmission delays larger than those calculated with the methods given here. Among the causes of longer delays are the following: traffic on the network, window sizes at network nodes, traffic through the Ethernet Unit (e.g., simultaneous socket servicing and FTP server communications, etc.), and the system configuration.
