    Regulatory notes 1. The MODG-100 is suitable for use in non-hazardous locations only. 2. The MODG-100 is not authorized for use in life support devices or systems. 3. Wiring and installation must be in accordance with applicable electrical codes in accordance with the authority having jurisdiction.

  • Page 12: Din Rail Mounting And Removal

    DIN rail mounting and removal The MODG-100 gateway is designed to be mounted on a 35 mm DIN rail according to DIN/EN 50022. The enclosure features a 35 mm profile at the back which snaps into the DIN rail. No tools are required for mounting. Please observe the rules outlined in the section called “Mounting rules”.

  • Page 13: Powering The Modg-100

    Wiring the RS-485/422 interface The RS-485/422 port is used for integrating the MODG-100 into a two-wire or four- wire Modbus over Serial Line network. The use of either the RS-485 or RS-422 interface must be configured using the web interface (See the section called “Configuring Modbus network”).

  • Page 14: Wiring The Rs-232 Interface

    The RS-232 port can alternativly be used for serial communication to a Modbus Slave device instead of RS-485. The use of the RS-232 interface must be configured using the web interface (See the section called “Configuring Modbus network”). The MODG-100 is a Modbus Master device on this interface.

    “Temporarily changing the IP settings on your PC”). In order to connect to the MODG-100 via TCP/IP, your PC must be on same IP subnet as the gateway. In most situations this means that the first three numbers of the IP address have to be identical.

  • Page 18: Ip Setup Using A Terminal Program Like Hyperterminal

    IP setup using a terminal program like HyperTerminal 1. Connect a null modem RS-232 cable between your PC and the MODG-100's Serial Port 1. 2. In Windows XP, click Start, point to All Programs, point to Accessories, point to Communications, and then click HyperTerminal.

  • Page 19: Temporarily Changing The Ip Settings On Your Pc

    This method involves manually assigning an IP address to your PC in the same subnet as the gateway. The default subnet of the gateway is 169.254.0.0/16. 1. Connect the MODG-100 to your Ethernet network. 2. On a Windows PC, open the Control Panel and double-click on Network Connections.

    Once you made sure that your PC is configured to be on the same subnet as the MODG-100, start your web browser. In the address box, type the IP address of your device (169.254.0.10 is the default), and then press Enter. (See Chapter 4, Ethernet &...

  • Page 22: Monitoring And Diagnostic

    In order to connect to the MODG-100 via TCP/IP, your PC must be on same IP subnet as the gateway. In most situations this means that the first three numbers of the IP address have to be identical. Monitoring and diagnostic The MODG-100 offers several web pages which allow monitoring of the status of the different communication networks and the device performance.

  • Page 23: Modbus Connection Status

    This page is automatically updated every 5 seconds. Figure 5.3: Modbus status page This page shows accumulated readings since the MODG-100 was last activated or reset. If power to the MODG-100 is lost, all cumulative values are reset to zero. The following statistics are maintained: TCP status Status of the Modbus/TCP connection as per TCP finite state machine (refer to RFC 793).

    Web browser based management The new settings are confirmed with the following page: Figure 5.6: IP settings changed to static IP confirmation Please write down the new IP address so you are able to communicate with the device in the future! Figure 5.7: IP settings changed to DHCP confirmation Configuring Modbus network The Modbus parameters for the serial line can be configured to match the serial line configuration of the other Modbus network nodes.
  • Page 28 The timing for the silence detection can be relaxed with this setting by adding small increments. This enables the MODG-100 to communicate with Modbus devices which may not be fully compliant to the Modbus specification in that respect.

    Web browser based management Once you click Save the new settings are stored and applied instantly. A confirmation message is shown. It is of great importance to ensure that there is not two devices with the same Modbus address. In such a case, an abnormal behavior of the whole serial bus can occur, the master being then in the impossibility to communicate with all present slaves on the bus.

  • Page 30: Backup And Restoring Of Configuration Settings

    Backup and restoring of configuration settings The MODG-100 allows configuration settings to be uploaded onto a PC. This is a beneficial for archiving purposes but also allows easy deployment of similar devices by the means of loading settings from a previously stored reference device.
