Connecting to a B&R device in B&R Automation Studio

Connecting to a B&R device over Ethernet or over a network is extremely helpful for updating and troubleshooting programs. Without a connection, a CompactFlash would have to be re-created for any small change that was made. In addition, it would be impossible to monitor the state of the program.

This article details how to connect to your B&R device over Ethernet and over a network.

Connecting to a Device over Ethernet

Purpose: Allows file downloads/transfers to the B&R device without re-flashing the Compact Flash each time.

Requirements: B&R device must be physically connected to computer over Ethernet.

  1. To check the current IP address of the device, navigate to Online > Settings.

    Check the current IP address of the device
     
  2. If the desired IP address is different from the current IP address of the device, navigate to Ethernet Configuration (Physical View > Right click main device > open Ethernet Configuration) and set the IP of device.

    Change the current IP address if it is not the desired IP address
     
  3. To ensure that communication will work between the computer and the device, set the computer’s IP address to an IP address with the same first 3 bytes. (Local Area Connection > TCP/IP > Set IP of device (modify the last digit so that they are not matching).

    Set the IP address to the same first three bytes.

If the IP address of the device was not changed, the device should be properly connected. Certain options that were previously unavailable (Transfer, Monitor, Stop Target, Warm Restart) will now be available. If the IP address of the device was changed, a new CompactFlash will need to be created. As a workaround to re-creating the CompactFlash, you can change your local settings to match those on the Compact Flash (which will allow for Transfers). Then, you can download the changes to the device IP without re-flashing the CF card. To re-connect, simply repeat steps 2-3.

Connecting to a Device over a Network

Purpose: Allows file downloads/transfer to the B&R device without direct physical connection, enables send to network locations functionality.

Requirements: Static IP address, B&R device and computer must both be connected to the same network and network settings.

  1. To set the IP address and subnet mask, navigate to the Ethernet Configuration Configuration (Physical View > Right click main device > open Ethernet Configuration) and set the IP and subnet of the device.


     
  2. To set the default gateway and DNS server address, navigate to AR Configuration (Physical View > Right click main device > open AR configuration) and set default gateway and DNS server address.

    Set the default gateway and DNS server address.
     
  3. If device was previously connected to the computer over Ethernet, transfer the new program to set the new network settings. After this transfer, the device will not be connected until the computer’s network settings are set to match the device’s network settings. If the device was not previously connected over Ethernet, create a new CompactFlash for the device to set the new network settings.
     
  4. On computer, set all the same parameters as are on the device. (Local Area Connection > TCP/IP > Set IP of device (same as device is on), set subnet mask, set default gateway, set DNS server).

    Set all the same parameters as are on the device.

dear Sir/Madam,
I am working in visual studio 2017 c# program and i want to connect my C# front end code with the B&R PLC hardware device for the back end support. How can i achieve this condition?

Hi Mahdi,

You will need to create a new CompactFlash the first time - this should allow you to set the IP address of the device. If you're having trouble connecting via network/Ethernet, you can always reflash the CompactFlash card. This should boot the program when the device powers up.

Nice information. For connecting to a Device over Network: A diagram showing the connections between the device, gateway and static IP will help understand the architecture in detail.

Thanks
