    Regulatory notes 1. The MBRG-300 is suitable for use in non-hazardous locations only. 2. The MBRG-300 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 MBRG-300 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 Mbrg-300

    Wiring the RS-485/422 interface The RS-485/422 port is used for integrating the MBRG-300 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 serial line Modbus”).

  • Page 14: Connecting Ethernet

    • The shield must not be connected to the GND pin. To connect the MBRG-300 to a PC (Personal Computer) or any other device with data terminal equipment (DTE) pinout you need a null-modem or cross-over cable.

    “Temporarily changing the IP settings on your PC”). In order to connect to the MBRG-300 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 MBRG-300’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 MBRG-300 to your Ethernet network. 2. On a Windows PC, open the Control Panel and double-click on Network Connections.
  • Page 20 8. Click Configuration… and then Ethernet & IP in the menu on the left side of the page. 9. Enter the IP address, subnet mask, and gateway address assigned to your MBRG-300, then click Save. 10.Restore your computer’s original settings.

  • Page 21: Web Browser Based Management

    Once you made sure that your PC is configured to be on the same subnet as the MBRG-300, 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 MBRG-300 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 MBRG-300 offers several web pages which allow monitoring of the status of the different communication networks and the device performance.

    Web browser based management Figure 5.3: Modbus status page This page shows accumulated readings since the MBRG-300 was last activated or reset. If power to the MBRG-300 is lost, all cumulative values are reset to zero. The following statistics are maintained: TCP status Status of the TCP/IP connection as per TCP finite state machine (refer to RFC 793).

    Baud rate 9600 and 19200 are the most common baud rates for Modbus. 19200 is the default setting. Data bits Only 8 data bits can be selected here which is a requirement for RTU. Stop bits Can be configured to be 1 or 2. The Modbus standard mandates that 2 stop bits are configured when using no parity.
  • Page 27 Web browser based management Please allow a few seconds before continuing working with the device as it has to fully start-up first, before being able to respond to further web browser requests. After a remote restart a Watchdog reset alarm is shown on the device' home page. This is a side-effect of the remote restart procedure and the alarm shall be ignored and cleared.
