  • Page 12 IP® use portions of the “Telnet Environment Option” (RFC1572) to verify that it is con- nected to an EDW-100. The EDW-100 has partial support for the “Telnet Com Port Control Option” (RFC2217). This makes it possible to remotely (on the fly) change serial port parameters. Currently supported parameters are baud rate, parity, number of data bits and number of stop bits.

  • Page 14: Transmission Control Protocol (Tcp)

    This mode makes it possible to establish a TCP connection to a remote TCP server e.g. a EDW-100 in TCP Server mode. DSR signal rising or a powering up the unit will trigger the EDW-100 to make an connection attempt to the specified server depending on configuration.
  • Page 15 Short description of Modbus Modbus is a communication protocol developed by Modicon systems. The EDW-100 Modbus gateway is used for interconnecting a TCP/IP Modbus network and a serial line Modbus network (either RTU or ASCII). It permits Modbus clients (masters) on either of the TCP/IP or the serial network to connect to Servers (slaves) on the other network.
  • Page 16 Modbus Slave 4 Setting up the EDW-100 as a Modbus Gateway Set the EDW-100 application mode to Modbus gateway to enable the gateway functional- ity. Serial settings and ip-configuration is shared whit the other application mode but the rest of the Modbus configuration is done on the specific Modbus configuration page. To set up the gateway it is necessary to know details about the TCP and the serial Modbus network.

  • Page 17: Packing Algorithm

    Packing algorithm When data arrives at the serial port of the EDW-100 there must be one or more criteria fulfilled to trigger the EDW-100 to encapsulate the received serial data into a frame and send it out on the network.

  • Page 25 The one to many function can be used in place of a traditional RS-422 or RS-485 multidrop application. Data entering one of the EDW-100 will be broadcast or Multicast to any other device in the broadcast or multicast group. A typical application would be a SCADA host computer communicating to a number of PLC’s.
  • Page 26 Network Description In a point to point application the EDW-100 can be to replace or extend a cable link. The distance between the EDW-100 units is only limited by the size of the LAN. Data can be sent across the network using ether UDP or TCP. A typical application would be a SCADA or Data logging application interrogating a sensor or PLC.
