Section 5-1 IP Addresses 5-1 IP Addresses Ethernet networks use IP addresses for communications. IP addresses identify both the Ethernet network and the node (host computer, Ethernet Unit, etc.). IP addresses must be set and controlled so that they are not duplicated. 5-1-1 IP Address Configuration IP addresses are made up of 32 bits of binary data divided into four 8-bit fields called octets. These four octets provide the network number (net ID) and host number (host ID).
Section 5-1 IP Addresses 5-1-3 Ethernet Unit IP Address Settings An IP address must be set even for the Ethernet Unit before Ethernet communications can proceed. Either use the default for the Ethernet Unit's IP address, or else use a Peripheral Device to set it in the DM Area words allocated to the Unit as a CPU Bus Unit or in the CPU Bus Unit System Setup. For details, refer to 2-7 Unit Setup Procedure.
Section 5-2 IP Addresses in FINS Communications 5-2 5-2-1 IP Addresses in FINS Communications Specifying Nodes in FINS Communications Services With FINS communications services on an Ethernet network, IP addresses, UDP port numbers, and TCP port numbers are paired with FINS node addresses to specify nodes on the network. Application level FINS Transport level UDP Internet level IP Node number TCP UDP port number TCP port number Must be allocated.
Section 5-2 IP Addresses in FINS Communications Pairing IP Addresses with FINS Node Addresses at Local Nodes A particular IP address is allocated to each communications node, including Ethernet Units. The IP address must be paired with the FINS node address (1 to 254) by one of the following methods. Automatic Generation Method (Dynamic/Static) Set the relation between the IP address and the FINS node address for the Ethernet Unit according to the following equation.
Section 5-2 IP Addresses in FINS Communications 5-2-2 Pairing Addresses in Internal Tables FINS/UDP Communications Methods Automatic Generation (Dynamic) When the Ethernet Unit is turned ON or restarted, the following values are set for addresses in the internal table.
Section 5-2 IP Addresses in FINS Communications IP Address Table Method With this method, FINS node addresses are converted to IP addresses based on a correspondence table (IP address table) that is preset in the Unit setup. The IP address table is set using the CX-Programmer in IP Address Table under Settings in the Unit Setup. It can be registered for nodes in different segments and with different network numbers.
Section 5-2 IP Addresses in FINS Communications • Connection method: FINS/UDP • FINS Node Address Not Registered to IP Address Table The following address is registered to the internal table. • Remote IP address: Local IP address network number + FINS node address • Remote UDP port number: UDP port number set for local Unit • Connection method: FINS/UDP With the combined method, records of FINS nodes registered to the IP address table are not dynamically changed.
IP Addresses in FINS Communications Using the ETN11compatible Mode Section 5-2 For Ethernet Unit with unit version 1.4 or later, operating specifications can be made compatible with the CS1W-ETN11/CJ1W-ETN11 for all methods (automatic generation (dynamic), I/O address table, or combined). (Dynamic changes, however, are prohibited for the destination IP address in ETN11compatible mode.
IP Addresses in FINS Communications Section 5-2 FINS/TCP Communications Method Pairing in the FINS/TCP Method Note Internal Processing With the FINS/TCP method, communications are first established for each connection, and then remote FINS node addresses are mutually converted. (See note.) Then FINS message communications are executed. In this way, remote FINS node addresses and remote IP addresses are paired for each connection.
Section 5-2 IP Addresses in FINS Communications Personal computer or Ethernet Unit (client) Ethernet Unit (server) (1) The connection is established. Local FINS node number A (2) The local device (such as a personal computer) sends notification that its FINS node number is A.
Section 5-2 IP Addresses in FINS Communications 5-2-3 Application Examples Responding to Computers with Changed IP Addresses FINS/UDP Communications Method With FINS/UDP, whether using the automatic conversion method (dynamic), the IP address table method, or the combined method, remote FINS node addresses and remote IP addresses in the internal table are changed after FINS messages are received.
Section 5-2 IP Addresses in FINS Communications applications, such as mail servers, are normally allocated fixed IP addresses. Ethernet Units in PLC systems are also allocated fixed IP addresses.

Also, with some communications companies, there may be restrictions, based on mail security considerations, on using POP before SMTP. 4.
SECTION 6 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 PLC are sent via the SEND(090), RECV(098), and CMND(490) instructions programmed into the user ladder-diagram program.
Section 6-1 Overview of FINS Communications 6-1 6-1-1 Overview of FINS Communications Communications On an Ethernet Network Data is sent and received as UDP/IP packets or TCP/IP packets on an Ethernet network. PLC or host computer Ethernet Unit Packet (FINS command) Ethernet Packet (FINS response) Ethernet Unit PLC In the FINS communications service, both an IP address for IP (the Internet layer) and a FINS node address for FINS (the application layer) are used for the remote device.
Section 6-1 Overview of FINS Communications • 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. Note FINS/TCP offers superior communications quality. • When the quality of connections is unreliable, as with wireless LAN: Use the FINS/TCP method between those nodes.
Section 6-2 FINS/UDP Method 6-2 6-2-1 FINS/UDP Method 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 relationship and there is no clear connection. If using TCP is like making a telephone call, then UDP is more like delivering a memo by hand.
Section 6-2 FINS/UDP Method UDP Port Numbers for FINS/UDP The UDP port number is the number for UDP to identify the application layer (i.e., the FINS communications service in this case). When communications are executed by UDP/IP, this port number must be allocated to the communications service. The default setting for the FINS/UDP local UDP port number (i.e., the Ethernet Unit's UDP port number) is 9600. To set another number, make the setting for the FINS/UDP port using the Setup Tab in the Unit Setup.
Section 6-3 FINS/TCP Method 6-3 6-3-1 FINS/TCP Method 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 virtual circuit, i.e., a connection. Once a connection has been established, communications are quite reliable.
Section 6-3 FINS/TCP Method • 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 Ethernet Ver. 2 The following diagram shows the structure of a TCP packet sent over an Ethernet network.
Section 6-3 FINS/TCP Method 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 terminated by a communications error or a FINS command (i.e., FINS/TCP CONNECTION REMOTE NODE CHANGE REQUEST).
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 connection used as the FINS/TCP client is the remote IP address set under the FINS/TCP Tab in the Unit Setup. To dynamically change the remote IP address (i.e.
Section 6-4 Creating Routing Tables 6-4 Creating Routing Tables When the FINS communications service is used, routing tables must be created in advance. Routing tables are required in the following circumstances. • When communicating with a PLC or computer on another network (e.g., remote programming or monitoring using FINS messages or a CX-Programmer) • When multiple Communications Units are mounted to a single PLC (i.e., CPU Unit).
Section 6-4 Creating Routing Tables The following example shows routing tables for sending data from PLC #1 (the local node: network address 1, node address 1) to PLC #4 (the destination node: network address 3, node address 2).

Section 6-7 Precautions on High Traffic in FINS Communications nodes, traffic through the Ethernet Unit (e.g., socket servicing, FTP server communications, etc.), and the system configuration. Example Calculations The following example shows calculations for receiving 256 words between two PLC nodes using RECV(098).
Precautions on High Traffic in FINS Communications Section 6-7 For example, suppose that approximately 20 ms are required to process a single FINS frame (i.e., 20 ms from the time that the command is received at the Ethernet Unit until a response is sent). If 100 or more FINS frames (commands) are received at once from multiple communicating nodes, it will take approximately 2 seconds to send a response to the last command.
