Introduction 1.1 1 Ethernet Web Embedded Server Modules The Quantum Ethernet Web embedded server modules make it possible for a Quantum industrial control system to communicate with devices on an Ethernet network. For example, the modules can be used to link a Quantum Automation Series controller to a PC. Each module contains a World Wide Web server, which allows users to obtain statistics about the NOE module and its controller from an embedded web site.
Introduction 1.1.2 Models for Fiber Optic and Twisted Pair Cable Systems Modicon has designed two Ethernet web embedded server modules: one for fiber optic networks and the other for networks using twisted pair cabling. Both are covered in this manual. Type of Cable Network 4 Part Number Twisted Pair 140 NOE 211 10 Fiber Optic 140 NOE 251 10 840 USE 115 00 Version 1.

Introduction 1.2.2 Address Labels Each Quantum Ethernet web embedded server module has two address labels. One identifies the Ethernet or MAC address. The other label allows you to record the module’s Internet Protocol (IP) network address. Ethernet Address Label The Ethernet address or MAC address is assigned at the factory and is recorded on a label on the front panel, above the cable connector. This is a unique 48-bit global assigned address. It is set in PROM.
Introduction Example Calculating the Derived IP Network Address Locate the global address label on the front panel of the module. IEEE GLOBAL ADDRESS 0000540B72A8 Note the rightmost eight digits. 5 4 0 B 7 2 A 8 Convert them from hexadecimal to decimal. Each pair of hexadecimal numbers will result in a decimal number between 0 and 255. This is the derived IP address. 84.11.114.
Introduction 1.2.3 Twisted Pair Connector Pins 8 1 Figure 5 NOE 211 Connector For the NOE 211, Schneider Automation recommends that you use Category 5 UTP cabling, which is rated to 100 Mbps, with an RJ-45 connector. You may also use Category 3 UTP cabling, which is rated to 16 Mbps. The eight pins are arranged vertically and numbered in order from the bottom to the top. The RJ-45 pinout used by this module is: z z z z 1.2.
Introduction 1.3 Utility Diskette Included with this manual is a diskette containing two utilities for the Ethernet module: the Network Options Ethernet Tester utility and the ERRLOG utility. 1.3.1 Network Options Ethernet Tester This utility will allow you to: z z z establish a connection get and clear statistics read and write registers The Network Options Ethernet Tester communicates with the module over the Ethernet, from an IBM-compatible PC operating with Windows 3.
Introduction 1.4 Ethernet and Your Application Careful planning of your network can help you achieve optimum performance. You should consider whether Ethernet meets the demands of your application, which devices are compatible with your network and how to minimize congestion on the network. 1.4.1 Meeting the Demands of Your Application The Quantum Ethernet web embedded server modules provide connectivity to many different systems via an Ethernet network.
Introduction Ethernet network traffic, message length and routing are all variable and can be unpredictable. This can give rise to congestion and message collisions. When collisions occur, Ethernet uses a variable delay before retransmitting messages. Therefore, absolute determinism -- or totally predictable performance -- cannot be guaranteed on busy Ethernet networks. 1.4.2 Compatibility Ethernet technology allows devices from different vendors to coexist on the same network.
Introduction Segregating Traffic The best method to protect Quantum Automation traffic from information systems traffic is to provide a completely separate physical network for automation control. Another method is to use readily available Ethernet devices such as bridges and routers to logically segment the network, isolating office traffic from control data. Minimizing Delays Components such as repeaters, bridges, routers and hubs take a finite time to process each message.
Installing and Configuring the Module 2.1 2 Before You Begin . . . Quantum Ethernet web embedded server modules come fully configured. They are designed to go straight from the box to the backplane. But before you install your module, you must verify that: z z the default configuration is appropriate for your network your Ethernet network is properly constructed CAUTION DUPLICATE ADDRESS HAZARD The default configuration includes the IP network address.
Installing and Configuring the Module Consult your network administrator to see if any of these conditions apply. If they do, follow the directions on page 20 for changing the default configuration. Note: If you will be changing the default configuration, you should stop the controller, then install the module, then change the configuration before starting the controller again. The Ethernet web embedded server module only reads its configuration data at power-up and when it is reset.
Installing and Configuring the Module 2.2 Installing the Module The Ethernet web embedded server module comes fully ready to be installed. Installation consists of mounting the module on the backplane and connecting the cable. 2.2.1 Are You Really Ready to Install? Check! Have you reviewed the configuration and network guidelines on page 15? You must meet those guidelines before installing the module.
Installing and Configuring the Module 2.2.3 Connecting the Cable Twisted Pair If you are using twisted pair cable, Modicon recommends Category 5, which is rated to 100 Mbps. Use RJ-45 connectors. Slip the connector into the port. It should snap into place. Fiber Optic Use 62.5/125 fiber optic cable with ST-style connectors. Modicon sells a 3 m cable with connectors (990 XCA 656 09). Remove the protective plastic coverings from the cable ports and the tips of the cable.
Installing and Configuring the Module Turn the locking ring to align an arrow with the key. Then align the key with the keyway. As a result, the locking tab, groove and lock should also be aligned. Slide the clasp up to the locking ring. Gripping the cable with the clasp, plug the cable into the lower (receive) cable connector. If it does not connect easily, realign the key with the arrow and try again.
Installing and Configuring the Module 2.3 Changing the Default Configuration If any of the following conditions apply, you should stop the controller, then install the module, then change the default configuration before starting the controller again: z z z z The module will be communicating on an open Ethernet network. The module’s IP address is already in use. The network uses IEEE 802.3 framing. You must specify a default Ethernet gateway and subnet mask.

Installing and Configuring the Module 2.4.3 Assigning the IP Network Address The Internet Protocol (IP) network address is a 32-bit address in the form xxx.xxx.xxx.xxx, where each group xxx is a decimal number ranging from 0 to 255. If the module will be communicating on an open network or if the module’s derived IP address is already being used, consult your network administrator to obtain a unique address. Type the new address in fields B4 through B1.
Installing and Configuring the Module 2.4.6 Configuring More Than One Ethernet Module You may configure from two to six Ethernet modules in a single controller, depending on the model. A 140 CPU 113 or 213 will accept a total of two network option modules, including NOE, NOM, NOP, CRP 811and other modules. A 140 CPU 424, 434 or 534 will accept six. The first Ethernet web embedded server module configured requires 20 words of memory. Each additional module requires an additional 16 words of memory.
Installing and Configuring the Module 2.5 Configuring the Module with Concept Once the Ethernet web embedded server module has been installed in the backplane and you have consulted your network administrator about whether to change the IP address or framing or to specify a gateway or subnet mask: 1. Open the Concept project without connecting to the controller. The controller and I/O should be configured. 2. Set the number of Ethernet modules in the configuration extension. 3.

Using the Network Options Ethernet Tester 5.1 5 Introduction An Ethernet module may act as a client or as a server. If it will be acting as a client -- that is, initiating transactions on the network for its Quantum controller -- then you must program an MSTR block in ladder logic. For details about the MSTR block, please refer to Chapter 3 on page 25. The Ethernet module may also act as a server, responding to requests and commands from devices on the network for its Quantum controller.

Maintenance 6.1 Responding to Errors 6.1.1 Detecting Errors 6 When faults occur, the LED display can help you determine what went wrong. During normal operation, the LEDs should display the following pattern: 140 NOE 211 10 ETHERNET TCP/IP Active Ready Run Link Figure 25 LED Display During Normal Operation 840 USE 115 00 Version 1.
Maintenance The Run indicator will flash. The Coll LED also may flash, indicating that collisions are occurring on the Ethernet network. Such collisions are normal. If a fault has occurred, the normal LEDs may be extinguished or other indicators may light. This section will discuss errors reported by the Active, Ready, Coll, Link, Kernel, Appl and Fault indicators. For each type of error, try the suggested remedies in the order given.
Maintenance 6.1.4 Link LED If the Link LED fails to light, the module is not communicating with the Ethernet hub. Troubleshooting 6.1.5 1. Make sure that the cable has been installed correctly and the module is functioning properly. 2. Verify that the hub is working properly. Kernel LED If the Ready LED is on and the Kernel LED is flashing, the module has detected an invalid software image.
Maintenance 6.1.7 Collision LED If the twisted pair cable has not been connected properly, the Coll LED will shine steadily and the Link LED will be extinguished. (This condition does not occur with fiber optic modules.) 140 NOE 211 10 ETHERNET TCP/IP Active Ready Coll Figure 27 LED Display for Improperly Connected Twisted Pair Cable Troubleshooting 1. Make sure the cable has been installed properly and is working properly. 2. Verify that the Ethernet hub is functioning properly.
Maintenance If the Coll LED is flashing, the module is reporting collisions on the Ethernet network. While such collisions are normal, the frequency of the flashes is an indication of the volume of traffic on the network. The flashes may be so frequent that the LED appears to be shining steadily. Heavy traffic will slow communications. If response time is important to your application, you should consider segmenting your network to reduce the frequency of collisions. 6.1.
Maintenance The default is 0. Example ERRLOG 49 1 This is the minimum command. It will display the error log of the Ethernet web embedded server module in slot 1 of the controller at Modbus Plus address 49. . Example ERRLOG 49.50 4 /d /s5d /n1 > TRACE.OUT This will display the error log of the Ethernet web embedded server module in slot 4 of the controller at Modbus Plus address 49.50. It will display debug information, use software interrupt 5d and use Modbus Plus adapter number 1.
Maintenance Example Sample Error Log Path DM. 24. 0. 0. 0. 0 was opened.

Maintenance 6.2 Hot Swapping An Ethernet Module You may replace your Ethernet web embedded server module while the controller is running. However, you should first make sure that the IP network address of the replacement module will be unique on your network. The new Ethernet module will inherit any configuration changes you had made. If the original Ethernet module was given a user-configured address, the new module will assume that address.
Maintenance 6.3 Downloading a New Software Image From time to time, Schneider Automation may release improved versions of the Quantum Ethernet embedded server firmware. These new software images may be downloaded through Modsoft using the following procedure. 1. Stop the controller. 2. From the main Modsoft menu, select Transfer. From the Transfer pulldown menu, select Download Exec. Figure 29 Main Menu Transfer Options 3. From the Device to Download menu, select Local Head.
Maintenance Now you must specify which PLC is controlling the Ethernet web embedded server module and the backplane slot (head) number for that module. 62 4. Modsoft will prompt you for the filename of the executive. It is referring to the new software image. Load the diskette with the file in the floppy drive and type the drive designation and filename in the space provided, separated by a colon, ie. a:\filename.ext. 5.

Ethernet Developers Guide B.1 B Introduction This appendix describes the design of the sample TCP/IP application named Network Options Ethernet Tester (NOET). The NOET application is a multiple document interface windows application that verifies the installation of the Quantum Ethernet TCP/IP module and also serves as a sample application for developers. TCP/UDP system port number 502 is used with ASA protocol_id of 0. B.2 References Inside Visual C++, Second Edition, David J.
Ethernet Developers Guide B.3 Overview The sample application performs the following steps: z z z z Invoke Identifier Calls the window socket function socket to create a socket. Calls the window socket function setsockopt to set the socket attributes. Calls the window socket function connect to establish a connection. Encodes the request. The request consists of a header followed by a Modbus message.
Ethernet Developers Guide B.5 Class Descriptions The following list describes the different classes: 840 USE 115 00 Version 1.0 1. CSample_app. The Csample_app is the application class. This application was generated by the application wizard, and the source is in the file sam_app.cpp. The class declaration is in sam_app.h. 2. CMainFrame. The CMainFrame is derived from the MFC class CMDIFrameWnd and is the application’s main window frame. The source for CMainFrame is in mainfrm.
Ethernet Developers Guide 9. CReadDlg. The CReadDlg class is the dialog class for determining the registers to read. It is derived from the CDialog class. The declaration is in the readdlg.h file, and the implementation is in the readdlg.cpp file. Both of these files were generated by The Visual C++ class wizard. 10. CWriteDlg. The CWriteDlg class is the dialog class for determining the registers to write and the write data. It is derived from the Cdialog class. The declaration is in the writedlg.
Ethernet Developers Guide B.7 The CSample_View Class The CSample_View class manages the TCP/IP connection, sends requests to remote nodes, and displays either connection state, or the results of a transaction. In addition it sets the states of the tool bar buttons and menu items. B.7.1 Accessing TCP/IP The CSample_View interfaces with window sockets via its application programming interface, and via messages sent by the window sockets DLL to the CSample_View window.
Ethernet Developers Guide One of the parameters to the WSAAsyncSelect is a user defined message the window socket DLL sends to the window. The sample application user message is WM_TCPIP_EVENT and is defined in the file wn_msh.h. MFC architectural framework calls the CSample_View tcpip_event member function to process this message. Like all functions which process messages, tcpip_event parameters are a word and a long word.
Ethernet Developers Guide B.8 Timers CSample_View requires to periodically receive a timer message. This message triggers the CSample_View to transmit a message. Since window timers are a limited resource, the window associated with CMainFrame class receives the timer messages. CMainFrame member AddTimerList function will place a window on its timer list. When CMainFrame processes the WM_TIMER message, it sends each window on its time list the user defined WM_POLL_INTERVAL message.
Ethernet Developers Guide B.10 Transmit State Machine The transmit state machine establishes a connection, and periodically transmits a request. The different states for the transmit state machine are as follows. z z z z z z z IDLE. In the IDLE state, there is no connection. RESOLVING_NAME. In the RESOLVING_NAME state, CSample_View is waiting for the window socket DLL to convert a node’s name into an IP address. CONNECTING.
Ethernet Developers Guide If the remote node is an IP address, or if it’s a name that has been resolved, then CSample_View tcpip_connect_rq function is called to initiate a connect request to the remote node. The listen port for the connect request is five hundred and two, and is defined by the constant MBAP_LISTEN_PORT in modbus.h. If tcpip_connect_rq succeeded in initiating a connect request, then tcpip_connect_rq changes the transmit state to CONNECTING, otherwise it changes the transmit state to IDLE.
Ethernet Developers Guide The receive state machine (which is described below) processes the response to a request. When the receive state machine has completed receiving the response, it changes the transmit state machine from the TX_DONE state to the WAIT_TO_TX state. Recall that the TransmitUserRequest saves the time. CSample_View OnPollInterval uses this saved time to determine if a new request needs to be transmitted.
Ethernet Developers Guide The receive state machine maintains a variable which is the number of bytes received. Initially the receive state machine is in the RX_HEADER state, and the number of bytes received is zero. When OnTcpIpRead is called and the receive state is RX_HEADER OnTcpIpRead calls rx_msg with receive size equal to the header size. On return OnTcpIpRead examines the number of bytes received.
Ethernet Developers Guide The member function rx_msg calls the window socket recv function to read data. The recv function either returns a non negative number that is the number of bytes read or it returns an error. If the number bytes read is zero, then the connection no longer exits, and rx_msg closes the socket, and sets the transmit state to IDLE. If the recv function returns the error indicating that no receive data is available, then rx_msg just returns.
Quantum Ethernet TCP/IP Modbus Application Protocol C.1 C Introduction The Modbus Application Protocol (MBAP) is a layer-7 protocol providing peer-topeer communication between programmable logic controllers (PLCs) and other host-based nodes on a LAN. Collectively these nodes implement all or part of a control application used for industrial automation applications in the automotive, tire and rubber, food and beverage, and utilities industries, to name a few.
Quantum Ethernet TCP/IP Modbus Application Protocol C.1.1 Modbus Application Protocol PDU The Modbus Application Protocol PDU, mbap_pdu, is received at TCP port number 502. The current maximum size of the mbap_pdu for this class of services is 256 bytes.
Quantum Ethernet TCP/IP Modbus Application Protocol Example Modbus Application Protocol PDU Here are the values for a sample mbap_pdu for reading a register: 00 01 00 00 00 06 01 03 00 00 00 01 This example has the folowing structure and content: inv_id 00 01 proto_id 00 00 len 00 00 dst_idx 01 func_code03 data C.1.2 00 00 00 01 Modbus Application Protocol Service Classes There are several classes of service that are part of the Modbus Application Protocol.
Quantum Ethernet TCP/IP Modbus Application Protocol C.2 Modbus Application Protocol PDU Analysis The Modbus Application Protocol PDU is transmitted over a TCP/IP Ethernet stack. Both Ethernet II and IEEE 802.3 framing will be accommodated. Ethernet II framing is the default. . . . from the wire in for IEEE 802.3 framing . . . . . . is IEEE 802.3 framing if length <=1500 . . . 802.3_pdu ::= {dst_addr[6], src_addr[6], length[2], data=802.2_pdu} *an IEEE 802.
Quantum Ethernet TCP/IP Modbus Application Protocol The header is 7 bytes long, and includes the following fields: inv_id[2 bytes] invocation id used for transaction pairing proto_id[2 bytes] used for intra-system multiplexing,default is 0 for Modbus services len[2 bytes] the len field is a byte count of the remaining fields and includes the dst_id and data fields. The remainder of the pdu includes two fields: dst_idx[1 byte] destination index is used for intra-system routing of packets.
Quantum Ethernet TCP/IP Modbus Application Protocol C.3 TCP/IP Specific Issues C.3.1 Broadcast/Multicast Although broadcast and/or multicast are supported by both IP network address and IEEE 802.3 MAC address, the Modbus Application Protocol does not support either broadcast or multicast at the application layer. Schneider Automation’s Quantum PLCs use broadcast addressing because they use ARP as the means of locating the destination node.
