3 01 INTRODUCTION The card device server connects the monoxide system to Ethernet networks using the IP protocol family (TCP for connection-oriented stream applications and UDP for datagram applications) NETWORK PROTOCOLS The card uses IP protocol for network communications. The supported protocols are ARP, UDP, TCP, ICMP, Telnet, TFTP, DHCP, HTTP, and SNMP. For connections to the serial port, TCP, UDP or Telnet protocols are used. Firmware updates can be performed using TFTP. The Internet Protocol (IP) defines addressing, routing, and data block handling over the network. The Transmission Control Protocol (TCP) assures that no data is lost or duplicated, and that everything sent to the connection arrives correctly at the target. For typical datagram applications in which devices interact with other devices without maintaining a point-to-point connection, User Datagram Protocol (UDP) is used PACKING ALGORITHMS Two software selectable packing algorithms define how and when packets are sent to the network. The standard algorithm is optimized for applications in which the card is used in a local environment, allowing for very small delays for single characters while keeping the packet count low. The alternate packing algorithm minimizes the packet count on the network, and is especially useful in applications in a routed Wide Area Network (WAN). Adjusting parameters in this mode can economize the network data stream ETHERNET (MAC) ADDRESS The Ethernet address is also referred to as the hardware address or the MAC address. The first three bytes of the Ethernet Address are fixed. The fourth, fifth, and sixth bytes are unique numbers assigned to each TCP2RS. Table 1.1.2: Sample Ethernet address A ó 00:20:4A:14:01: INTERNET PROTOCOL (IP) ADDRESS Every device connected to an IP network must have a unique IP address. This address is used to reference the specific card. See paragraph 10 for more information on IP Addressing PORT NUMBER Every TCP connection and every UDP datagram is defined by a destination IP address and a port number. For example, a Telnet application commonly uses port number 23. A port number is similar to an extension on a PBX system. Página 3 de 58

4 02 INSTALLATION This chapter describes the card and shows how to install it on a basic network PRODUCT DESCRIPTION NETWORK INTERFACE The card contains an RJ45 10Base-T Ethernet port that supports up to 10 Mbps or 100Base-TX Ethernet port that supports up to 100 Mbps. Figure 2.1.2: Network interface PRODUCT INFORMATION LABEL A product information label is located on the underside of the card, and contains the following information about your specific unit: - Ethernet Address (also referred to as Hardware Address or MAC Address) INSTALLING THE CARD This section defines the steps to take to install the systems properly. The installer must read the whole manual before starting to install the system. Not following the instructions in this manual can damage the unit.. The card installation requires the following steps: 1.- Disconnect the monoxide system from the mains. 2.- Remove all modules of monoxide, removing the 4 screws and the connector plugged into the connector JP14. (Fig ) 3.- Locate and fix the expansion card using the same screws that came with the motherboard. (Fig.2.2.2). After fixing the card, connect the connectors that you had removed for the JP14 connector, connectors IN1, IN2, IN3 for the regulation card. 4.- Reattaching the monoxide modules system, one to one, connecting the hoses JP13, JP14, JP15 at JP6 connector of each module. 5.- Connect the cable from the connector on the expansion card, marked OUT 28V, and the power connectors JP14 of the monoxide modules. 6.- f you want that the system to work with batteries connect the battery cable to the connector on the card labeled BAT. 7.- If you are installing the card with the Ethernet Gateway do not forget to connect an Ethernet cable to the RJ45 (10BASE-T / 100Base-TX port).

6 Figure GETTING STARTED This chapter convers the required steps to get the card on-line and working. There are two basic methods used to log into the card and setup the IP address: - Network port login (1): Make a Telnet connection to the network port (port 9999) - Network port login (2): Using the software DeviceInstaller provided for the manufacturer for the Embedded Ethernet Device Server (XPort ). It is important to consider the following points before logging into and configuring the card: - The card s IP address must be configured before a network connection is available. - Only one person at a time may be logged into the configuration port (port 9999). This eliminates the possibility of several people simultaneously attempting to configure the card. - Network port logins cannot be disabled. The system manager will always be able to access the unit. However, this port can be password protected DEFAULT IP ADDRESS Provided a DHCP server exists on the network, it will supply the card with an IP address, gateway address and subnet mask when the card boots up. Página 6 de 58

7 03.02 IP ADDRESS CONFIGURATION The card s IP address must be configured before a network connection is available. If the IP address was not set automatically via DHCP, set it now using a network port login and the setup (configuration) menu NETWORK PORT LOGIN (1) The easiest way for setting up the IP direction of the card is using the utility called DeviceInstaller. It can be downloaded in the manufacturer s web page. First of all we will write down Ethernet address that comes printed on every device label. This address is unique and different from other network devices. It s the hardware address that every interface has (something like A-A5-C6-A2). Into the CD that comes with the converter, there is an utility called TCP2RSSetup. This utility is made for configuring the IP address of the converter. Steps: 1. Start the program 2. The software shows all devices avalaibles in the network and the IP address for each one. Figure Página 7 de 58

8 3. Select one device and check that the MAC o Hardware Address is the same that the IP address to change. Figure Press the bottom Assign IP to run the device IP configuration wizard. Figure Página 8 de 58

9 NETWORK PORT LOGIN (2) The ARP method is available under UNIX and Windows-based systems. If the card has no IP address, it will set its address from the first directed TCP/IP packet it receives. 1. On a UNIX host, create an entry in the host s ARP table using the intended IP address and the hardware address og the card, which is found on the product label. Figure : ARP on UNIX arp s :20:4A:xx:xx:xx In order for the ARP command to work on Windows, the ARP table on the PC must have at least one IP address defined other than its own. If the ARP table is empty, the command will return an error message. Type arp a at the DOS command prompt to verify that there is at least one entry in the ARP table. If the local machine is the only entry, ping another IP address on your network to build a new entry in the ARP table; the IP address must be a host other than the machine on which you are working. Once there is at least one additional entry in the ARP table, use the following command to ARP an IP address to the card: Figure : ARP on Windows arp -s a-xx-xx-xx 2. Now open a Telnet connection to port 1. The connection will fail quickly, but the card will temporarily change its IP address to the one designated in this step. Figure : Telnet to port 1 telnet Finally, open a Telnet connection to port 9999 and set all required parameters. Figure : Telnet to port 9999 telnet Note: This IP address is temporary and will revert to the default vale when the card s power is reset, unless you log into the card and store the changes permanently. Página 9 de 58

10 04 CONFIGURATION Certain parameters must be configured before the card can function on a network. The card can be locally or remotely configured using the following procedures: - Use a standard web browser to access the card s internal web pages and configure the unit over the network. This is the easiest and preferred method. - Use a Telnet connection to configure the unit over the network. - The card s configuration is stored in non-volatile memory (NVRam), and is retained without power. The configuration can be changed at any time. The card s performs a reset after the configuration has been changed and stored. Página 10 de 58

11 04.01 NETWORK CONFIGURATION USING A WEB BROWSER If your card already has an IP address (see Chapter 3, Getting Started), you can log into it using a standard Web browser with Java enabled. 1. Type the card s IP address into the web browser s URL (Address/Location) field. 2. Once you have connected to the card, you will see the device web manager interface.

16 05 PROTOCOLO MODBUS INTRODUCTION The Modbus protocol is a communications standard in the industry that allows to connect multiple devices. Modbus has a fixed communications format, from commands up to the frames of the messages. There are three different implementations of Modbus protocol: Modbus RTU, Modbus ASCII y Modbus/TCP (RTU o ASCII). A typical Modbus RTU message has the following format: Tabla 5.1 Address Command Data CRC 1 bytes 1 bytes n bytes 2 bytes The data field depends on the function implemented ERROR CODES In case of error the MODBUS frame get a response like to the following format: Table Address Error message CRC 1 byte 0x81 0x02 2 bytes The error message will consist in two bytes where the first is an AND between 0x80 and the command code (if function 1 -> 0x81, function 5 -> 0x85, 0x10 function -> 0x90, etc..) and the second byte will be a general identifier of the type of error: Table ERROR Name Description 1 Command The function code is not available 2 Address data The address of the data is incorrect or does not match with the data viewable or modifiable 3 Data value The value of the data is not correct 4 Device failure The device has failed to make the request 5 ACK The device has accepted the request but it cannot answer at this time. It should not be retried. 6 Device busy The device is making the request and it cannot replay a new one. It should be retried. Página 16 de 58

17 05.03 IMPLEMENTED COMMANDS The Modbus protocol commands implemented in the CO control panel are: - Command 01 (0x01): Read relay or inputs. - Command 04 (0x04): Read registers. - Command 16 (0x10): Write multiple registers MODBUS FRAMES EXAMPLES In the following lines we will see examples of the Modbus protocol frames. Frames to read and frames to write. Also frames to write the internal registers READ RELAYS OR INPUTS Request modbus frame: Table Address Command Dirección (2 Bytes) Data (2 bytes) CRC (2 bytes) 0x01 0x01 0x00 0x00 0x00 0x03 0x7C 0x0B Reply modbus frame. One bit for each input. ON Status = 1 and OFF Status = 0. Table Address Command Num. Bytes Data CRC 0x01 0x01 0x01 0x03 0x90 0x48 The value 0x03 will indicate that the input 1 and 2 are enabled (0x03 corresponds to the binary code ).

26 09 TECHNICAL SPECIFICATIONS Network interface Interface Connector Protocols Ethernet 10Base-T / 100Base-TX (auto-sensing) RJ45 MODBUS/TCP, ARP, ICMP, SNMP, TFTP, DHCP, BOOTP, HTTP y AutoIP 10 IP ADDRESSING Every device connected to a TCP/IP network must have a unique IP (Internet Protocol) address. This address is used to reference the specific device; for example, to build a connection to the card. An IP address is a 32-bit value divided into four octets of eight bits each. The standard representation is four decimal numbers (0-255) divided by dots (decimal dot notation). Figure 10: Sample IP address (or ) The IP address is divided into two parts: network and host. To support different needs, three network classes have been defined. In the following, "x" stands for the host part of the IP address CLASS A NETWORK IP address 1.x.x.x to 127.x.x.x The first byte defines the host, and the last three bytes define the network. Only 127 different Class A networks exist, and each can consist of up to 16,777,216 devices. Figure 10.1: Sample Class A network IP address (Network 10, host 0.0.1) CLASS B NETWORK IP address x.x to x.x The first two bytes define the host, and the last two bytes define the network. Class B networks are typically used for large company networks, and each can consist of up to 65,534 devices. Figure 10.2: Sample Class B network IP address (Network 172.1, host 3.2) Página 26 de 58

27 10.03 CLASS C NETWORK IP address x to x The first three bytes define the host, and the last byte defines the network. Class C networks are the most common and are often used in smaller companies. Each network can consist of up to 254 hosts. Figure 10.3: Sample Class C network IP address (Network , host 9) CLASS D NETWORK IP address 224.x.x.x to 239.x.x.x These addresses are used as multicast addresses CLASS E NETWORK IP address 239.x.x.x to 254.x.x.x These addresses are reserved NETWORK ADDRESS A host address with all host bits set to 0 addresses the network as a whole (for example, in routing entries). Figure 10.6: Sample network address DIRECCIONES DE BROADCAST A host address with all host bits set to 1 is the broadcast address, meaning for for every station. Figura 10.7: Dirección ejemplo de broadcast Network and broadcast addresses must not be used as a host address; for example, identifies the Entire network, and identifies the broadcast address. Página 27 de 58

28 10.08 IP NETMASK A netmask divides IP address differently than the standards defined by the classes A, B, and C. A netmask defines the number of bits to be taken from the IP address as the network or host sections. The card prompts for the number of host bits to be entered and then calculates the netmask, which is displayed in standard decimal-dot notation (for example, ) when saved parameters are displayed. Table10.8.1: Standard IP network netmasks Network class Network bits Host bits Netmask A B C Table : Netmask examples Netmask Host bits Página 28 de 58

29 10.09 PRIVATE IP NETWORKS AND INTERNET If your network is not and will not be connected to the Internet, you may use any IP address. If your network is connected or will be connected to the Internet, or if you intend to operate the card on an intranet, you should use one of the reserved sub-networks. Consult your network administrator with questions about IP address assignment NETWORK RFCS For more information about IP addresses, refer to the following documents, which can be located on the World Wide Web using one of the following directories or indices: - RFC 950 Internet Standard Subnetting Procedure - RFC 1700 Assigned Numbers - RFC 1117 Internet Numbers - RFC 1597 Address Allocation for Private Networks Página 29 de 58

32 01 INTRODUCCIÓN La tarjeta conecta el sistema de monóxido a una red Ethernet usando el protocolo IP (MODBUS/TCP para comunicaciones orientadas a conexión) PROTOCOLOS DE RED La tarjeta utiliza el protocolo IP para las comunicaciones en red. Los protocolos soportados son ARP, MODBUS/TCP, ICMP, Telnet, TFTP, DHCP, HTTP y SNMP. Para conexiones al puerto serie, se usan protocolos MODBUS/TCP o Telnet. Para actualizar el software interno del equipo se puede hacer usando el protocolo TFTP. El protocolo IP define el direccionamiento, enrutado y manipulación de datos a través de la red. El protocolo MODBUS/TCP asegura que no se pierdan o dupliquen datos, y que todo lo que es enviado llega a su destino correctamente ALGORITMOS DE EMPAQUETADO Mediante software, podemos elegir 2 algoritmos de empaquetado distintos, los cuales definirán como y cuando son enviados los paquetes a la red. El algoritmo estándar está optimizado para aplicaciones en las que la tarjeta es usada en pequeñas redes locales, permitiendo esperas muy bajas y manteniendo el envío de paquetes muy constante. El otro algoritmo de empaquetado minimiza la frecuencia de envío de los paquetes en la red, y está especialmente diseñado para aplicaciones en redes WANs o enrutadas. Ajustando los parámetros en este modo, podemos optimizar la red DIRECCIÓN HARDWARE (MAC) La dirección Ethernet es la dirección hardware del equipo o también llamada dirección MAC. Esta dirección viene fijada de fábrica y en cada equipo es diferente. Los bytes cuarto, quinto y sexto son los que definen cada tarjeta. Tabla 1.1.2: Dirección Ethernet ejemplo A ó 00:20:4A:14:01: DIRECCIÓN IP Cada equipo conectado a una red IP debe tener una única dirección IP. Esta dirección es usada para distinguir cada equipo. Mirar apartado 10 para más información acerca del direccionamiento IP NÚMERO DE PUERTO Cada conexión MODBUS/TCP está definido por una dirección IP destino y un número de puerto. Por ejemplo, un telnet generalmente utiliza el puerto 23. Página 32 de 58

33 02 INSTALACIÓN Este capítulo describe la tarjeta y muestra como instalarlo en una red. La instalación del equipo se realiza dentro de la central de monóxido, quedando todas las conexiones en el interior de esta DESCRIPCIÓN DEL EQUIPO INTERFACE DE RED La tarjeta tiene un puerto Ethernet RJ45 de 10 Mbps (10Base-T) o de 100 Mbps (100Base-TX). Figura 2.1.1: Interface de red ETIQUETA DE INFORMACIÓN DEL PRODUCTO En la parte lateral de la tarjeta existe una etiqueta de información, y contiene los siguientes datos del equipo: - Dirección Ethernet (también llamada dirección Hardware o dirección MAC) INSTALANDO LA TARJETA Este capítulo define los pasos a seguir para una correcta instalación de las tarjetas. El instalador debe leer todo el manual antes de empezar la instalación del sistema. No seguir las instrucciones de este manual puede ocasionar daños al equipo. La instalación de la tarjeta requiere los pasos siguientes: 1.- Desconectar el sistema de monóxido de la red. 2.- Desmontar todos los módulos de CO del sistema de monóxido, extrayendo los 4 tornillos por módulo y el conector enchufado en el conector JP14. (Fig ) 3.- Ubicar y fijar la tarjeta de expansión mediante los tornillos de fijación que se suministran junto con la placa. (Fig.2.2.2). Una vez fijada la tarjeta, conecte los conectores que ha extraído del conector JP14 de los módulos, a los conectores IN1, IN2, IN3 de la tarjeta de regulación. 4.- Volver a fijar los módulos del sistema de monóxido, uno a uno, conectando las mangueras JP13, JP14, JP15 en el conector JP6 de cada módulo. 5.- Conectar el cable entre el conector de la tarjeta de expansión marcado como OUT 28V y los conectores de alimentación de los módulos de monóxido JP Si se quiere que el sistema funcione con baterías conectar el cable de la batería al conector de la tarjeta de expansión marcado como BAT. 7.- Si se está instalando la tarjeta con pasarela Ethernet, conectar un cable Ethernet al puerto RJ45 (10Base-T / 100Base-TX).

35 Figura PUESTA EN MARCHA Este capítulo describe los pasos necesarios para poner en marcha la tarjeta. Existen dos métodos para comunicar con el conversor de la tarjeta y configurar la dirección IP: - Acceso por red (1): Haciendo un telnet al puerto Acceso por red (2): Utilizando el programa DeviceInstaller facilitado por el fabricante del Embedded Ethernet Device Server (XPort ). Es importante tener en cuenta los siguientes puntos antes de empezar a configurar la tarjeta: - La dirección IP de la tarjeta tiene que ser configurada antes de que se pueda establecer una conexión por red. - Sólo se puede establecer una conexión al puerto 9999 a la vez. Se elimina la posibilidad de que varias personas intenten configurar la tarjeta simultáneamente. - No se puede desactivar el acceso a este puerto, pero se puede proteger con contraseña DIRECCIÓN IP POR DEFECTO La tarjeta viene configurada en DHCP. Si se dispone de un servidor DHCP, este asignará automáticamente una dirección IP, puerta de enlace y máscara de subred a la tarjeta cuando éste se reinicie. Página 35 de 58

36 03.02 CONFIGURACIÓN DE LA DIRECCIÓN IP La dirección IP de la tarjeta debe ser configurada para que se pueda acceder a través de red. Si la dirección IP no ha sido asignada automáticamente por DHCP, se tendrá que configurar usando un puerto de red LOGIN POR EL PUERTO DE RED (1) El método más sencillo para configurar la dirección IP es mediante el programa DeviceInstaller. Este puede descargarse en la web del fabricante. Empezaremos apuntando la dirección Ethernet que viene en la etiqueta de cada equipo, la cual es única y distinta en todos los dispositivos de red. Es la dirección Hardware que toda interface de red tiene (ésta será del tipo A-A5-C6-A2). DeviceInstaller configurará de forma permanente la dirección IP del conversor. Los pasos a seguir son los siguientes: 1. Ejecutar el programa. 2. El programa mostrara los dispositivos disponibles en nuestra red y la dirección IP que estos tienen dentro de la misma.
