  • Page 11: Bus Coupling

    At least, the following components are required to operate an FTC470XET: A network-capable computer with Ethernet connection and a frame-capable Web browser. The FTC470XET user interface has been optimised for displays with a resolution of 1024 x 768 pixels. An Ethernet connection with a cross over patch cable, STP, RJ45 plug.
  • Page 12: Standard Application

    Bus coupling 3.2 Standard application In order to use BMS data, connect the internal FTC470XET Web server via the Ethernet/TCP/ IP interface to the local TCP/IP network (LAN), for example. Then the internal Web server can be queried and parameterised with frame-capable Web browsers. The diagram below shows how to access BMS devices via Internet and from a local network.

    If it fails to take over the master function, address 3 will be the next and so on. That means that an FTC470XET with BMS address 2 is more likely to take over the redundant master function than a device with address 30.
  • Page 17: Ethernet Side Of The Ftc470Xet

    "Basic configuration" on page 19. 4.6 Intended use The FTC470XET protocol converter connects the serial Bender BMS bus to a TCP/IP network via Ethernet. The converter is capable of transmitting data from the BMS bus to the TCP/IP network and vice versa.

  • Page 19: Installation

    Prior to installation and connection, an address has to be assigned to the FTC470XET. What you need is: A free BMS address between 2 and 30 for FTC470XET or a permission to assign the master function to the device, that means, BMS address 1 is assigned to the FTC470XET.
  • Page 20: Adapting A Single Pc To The Network Parameters Of The Ftc470Xet

    For changing the default network parameters of your single PC: (e.g. with Windows 2000) proceed as follows: 1. Connect the PC to the FTC470XET with a cross-over-patch LAN cable. 2. Now open the start page using the path Start/Settings/Network and DFÜ connections. There dou- ble-click ( your) LAN connection.
  • Page 21: Setting The Ip Address And Network Mask Of The Ftc470Xet

    Confirm with "Send" Now you have access to the parameterisation functions. 4. Click FTC470XET (mostly address 1) in the BMS Explorer in order to view the sub menu items. Then select "Set network parameters", the appropriate window will appear. 5. By way of example, it is assumed that you have received the following network data for the FTC470XET from the person responsible for the installation: IP address: 172.16.10.54...
  • Page 22: Resetting The Network Parameters To Factory Setting

    Installation server is now only accessible via the new IP address. Close the browser. After approximately 30 seconds, the FTC470XET will be ready for operation again, signalled by a per- manently lit green ON LED. 7. Change the IP address and net mask of your single PC once again in order to be able to address the FTC470XET although it has got a new address.
  • Page 23: Mounting And Connection Of The Device

    The following description is based on the assumption that the device is connected to a local network (LAN). 1. DIN rail mounting Snap the clamping springs at the rear of the FTC470XET into place in a way that a tight and secure fit is ensured. 2. Connection to supply voltage U Connect the terminals A1 and A2 to a supply voltage of U = 85 to 275 V (AC/DC).
  • Page 24: Wiring Diagram

    IP Address, Net Mask, Password Fig. 5.1: Wiring diagram for FTC470XET Do not wire the terminals GND and IN permanently with a bridge. A permanently con- nected bridge and the Reset button pressed would automatically reset the network parameters to the factory setting. This may cause serious malfunctions in installations under operating conditions.
  • Page 25: The User Interface Of The Internal Web Server

    Configuration of the browser In order to be able to query and parameterise the FTC470XET smoothly, it is necessary to enable cookies and to minimise the security restrictions.
