How to Find out the IP Address of an Omron
Communications Middleware/Network Browser How to find an Omron Controller’s IP address Valin Corporation | www.valin.com Overview • Many Omron PLC’s have Ethernet ports or Ethernet port options • The IP address for a PLC is usually changed by the programmer • Most customers do not mark the controller with IP address (label etc.) • Very difficult to communicate to the PLC over Ethernet if the IP address is unknown. Valin Corporation | www.valin.com Simple Ethernet Network Basics IP address is up to 12 digits (4 octets) Ex:192.168.1.1 For MOST PLC programming applications, the first 3 octets are the network address and the last is the node address. In above example 192.168.1 is network address, 1 is node address. For devices to communicate on a simple network: • Every device IP Network address must be the same. • Every device node number must be different. Device Laptop EX: Omron PLC 192.168.1.1 192.168.1.1 Device Laptop EX: Omron PLC 127.27.250.5 192.168.1.1 Device Laptop EX: Omron PLC 192.168.1.3 192.168.1.1 Valin Corporation | www.valin.com Omron Default IP Address • Most Omron Ethernet devices use one of the following IP addresses by default. Omron PLC 192.168.250.1 OR 192.168.1.1 Valin Corporation | www.valin.com PING Command • PING is a way to check if the device is connected (both virtually and physically) to the network. • Windows Command Prompt command. • PC must use the same network number as device (See previous) • Example: “ping 172.21.90.5” will test to see if a device with that IP address is connected to the PC. -

Cs-204: Computer Networks
CS-204: COMPUTER NETWORKS Lecture 5 Chapter 19- Network Layer: Logical Addressing Instructor: Dr. Vandana Kushwaha 1. INTRODUCTION Communication at the network layer is host-to-host (computer-to-computer); a computer somewhere in the world needs to communicate with another computer somewhere else in the world. Usually, computers communicate through the Internet. The packet transmitted by the sending computer may pass through several LANs or WANs before reaching the destination computer. For this level of communication, we need a global addressing scheme; we called this logical addressing or IP address. 2. IPv4 ADDRESSES An IPv4 address is a 32-bit address that uniquely and universally defines the connection of a device (for example, a computer or a router) to the Internet. IPv4 addresses are unique. They are unique in the sense that each address defines one, and only one, connection to the Internet. Two devices on the Internet can never have the same address at the same time. But by using some strategies, an address may be assigned to a device for a time period and then taken away and assigned to another device. On the other hand, if a device operating at the network layer has m connections to the Internet, it needs to have m addresses. A router is such a device which needs as many IP addresses as the number of ports are there in it. 2.1. Address Space A protocol such as IPv4 that defines addresses has an address space. An address space is the total number of addresses used by the protocol. If a protocol uses N bits to define an address, the address space is 2N because each bit can have two different values (0 or 1) and N bits can have 2N values. -

With IP In a previous article we discussed addressing, servers and IPv4 is called a classful system the Internet Protocol and the workstations are all termed hosts under RFC 761 with IP addresses structure of IP addresses. An IP but each address not only identifies being defined as belonging to one address identifies the source and a host but the address of the of five classes A, B, C, D or E. destination of a directed or unicast network on which the host resides. Classes A, B and C define different possible combinations of network message and is defined in RFC 761. This is because IP is an and host addresses. Class D is IPv4 is the most common version internetworking protocol that not reserved for multicasting. of IP addressing requiring 32-bit only allows communication Multicasting is the ability of one addresses. Although IPv6, the 128- between hosts on the same host to communicate with many bit version, will be used in the network, but communication other hosts with one transmission future, this article will restrict the between hosts on different and is beyond the scope of this discussion to IPv4. -

The Networker's Guide to Appletalk, IPX, and Netbios
03 9777 CH03 5/21/01 3:42 PM Page 85 3 The Networker’s Guide to AppleTalk, IPX, and NetBIOS UNTIL THE EARLY 1990S,TCP/IP WAS REALLY ONLY PREVALENT in large govern- ment and research facilities where UNIX and other supercomputing operating systems used it as a common network communications protocol.When PCs came into the picture, they were not networked. Rather, they were used either as front-ends to big micro or mainframe systems (IBM was a big fan of this approach) or as standalone sys- tems. In the early 1980s, as PCs grew in number and in performance, three strategies emerged to provide PCs with networking services:AppleTalk, Novell NetWare, and IBM’s NetBIOS. The goal of this chapter is to give you an understanding of the various protocols that make up the protocol suites and the roles they perform. It is not intended to explain how to design, set up, and manage a network. Chapter 7,“Introduction to Cisco Routers,” and Chapter 10,“Configuring IP Routing Protocols on Cisco Routers,” discuss configuration issues for these protocols. Because NetBIOS is a ses- sion layer protocol rather than a protocol suite, it will be described in the context of its operational behaviors at the end of this chapter. 03 9777 CH03 5/21/01 3:42 PM Page 86 86 Chapter 3 The Networker’s Guide to AppleTalk, IPX, and NetBIOS AppleTalk AppleTalk was an outgrowth of the Apple Macintosh computing platform.

An Internet Protocol (IP) Address Is a Numerical Label That Is
Computer Communication Networks Lecture No. 5 Computer Network Lectures IP address An Internet Protocol (IP) address is a numerical label that is assigned to devices participating in a computer network, that uses the Internet Protocol for communication between its nodes. An IP address serves two principal functions: 1- host or network interface identification 2- location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there." The designers of TCP/IP defined an IP address as a 32-bit number and this system, known as Internet Protocol Version 4 or IPv4, is still in use today. However, due to the enormous growth of the Internet and the resulting depletion of available addresses, a new addressing system (IPv6), using 128 bits for the address, was developed in 1995. Although IP addresses are stored as binary numbers, they are usually displayed in human-readable notations, such as 208.77.188.166 (for IPv4), and 2001:db8:0:1234:0:567:1:1 (for IPv6). The Internet Protocol also routes data packets between networks; IP addresses specify the locations of the source and destination nodes in the topology of the routing system. For this purpose, some of the bits in an IP address are used to designate a sub network. As the development of private networks raised the threat of IPv4 address exhaustion, RFC 1918 set aside a group of private address spaces that may be used by anyone on private networks. They are often used with network address translators to connect to the global public Internet.
