  • Page 5: Overview

    Connectivity can be easily achieved between any master(s) and any public slave(s) anywhere on an Ethernet network. Combined with a ICDM-RX/MOD running the Modbus/TCP application, both serial and Ethernet TCP/ IP Raw/ ASCII devices can be accessed anywhere on a network from any Modbus master.
  • Page 6 ICDM-RX/MOD User Manual Overview Term Definition A form of Ethernet connectivity that provides a level of guaranteed delivery and data Ethernet TCP/IP verification. This is used for many upper layer protocols such Modbus/TCP and can be also used for transferring Modbus/RTU and Modbus/ASCII messages.

    Remote serial Modbus/RTU and/or Modbus/ASCII devices through gateways (such as the ICDM-RX/MOD running the Modbus Router or Modbus/TCP applications). • Remote serial or Ethernet TCP/IP ASCII devices (barcode scanners, printers, RFID readers, visions systems, etc) through a gateway (such as the ICDM-RX/MOD running the Modbus/TCP application).

  • Page 9: Modbus Router Functionality

    All messages received from any Ethernet TCP/IP Master connection enter the routing functionality and can be routed to any local or remote device. Combined with a serial port redirector, such as the Pepperl+Fuchs Comtrol Secure Port Redirector, can provide COM port functionality from a computer to the Modbus network.

  • Page 16: Modbus/Rtu And Modbus/Ascii To-Slaves Interface

    The ICDM-RX/MOD translates various Modbus formats and forwards them to public slave devices attached to the Modbus To-Slaves configured serial ports. Each Modbus message is transmitted and a response is expected. The ICDM-RX/MOD times out the Modbus messages if there is no response returned within the configured timeout period.
  • Page 17 However, if more than one port is configured for Modbus To-Slaves on a ICDM-RX/MOD 2- or 4-port, the device must be found. The following is an explanation of how the search algorithm works on a ICDM-RX/MOD 2- or 4-port.

  • Page 18: Local Public Modbus Slave Device Search Methodology

    ICDM-RX/MOD User Manual Overview Allows the ICDM-RX/MOD to search for lost devices on all Modbus To-Slaves ports with the Lost Device Search Enable option turned on. This will cause timeout delays on all Modbus To-Slaves ports with the Device Search Enable option turned on until the device is found.
  • Page 19 ICDM-RX/MOD User Manual Overview This functionality is described in the following diagram: Alias Device ID and Device ID Functionality Note 1:Originally received Modbus messages. All responses will be returned with the original device ID. Note 2:Modbus messages sent to and responses received from Modbus Message Routing Handler.

  • Page 20: Alias Modbus Device Id Functionality

    ICDM-RX/MOD User Manual Overview 1.7.1. Alias Modbus Device ID Functionality The Alias Modbus Device ID functionality allows modification of device IDs only when messages are received from Modbus masters. When configured, a Modbus message from a master with the specified device ID is converted to the alias device ID, the message is then routed internally using the alias device ID.
