This prevents the plc from restarting if the power is interrupted and returns within this time frame. Nothing will happen, all Berghof devices have a built-in polarity protection and the device simply remains off. The device will not be damaged. The next step is setup the IP adress of the pc or laptop to one in the same subnet as the plc and then enter web interface to change all settings as needed.
In the rare case that a controller does not react after switching on and you cannot connect to it, there is still the possibility to read the system status from the LEDs. For everyday use the plc has an Ethernet port which can either be connected to the PC directly or to a network switch. However the Ethernet settings on the plc and on the PC have to be correct in order for both devices to be able to connect.
For controllers which have more than one Ethernet port, the standard Ethernet interface ETH0 the first port. On the CC-Prime models this is the port with the designation X10, but alternatively X11 and X12 can also be used here because XX12 is a switch integrated in the controller and connect to the same Ethernet interface. In the standard setting of the controller, this interface is configured as an EtherCAT port, alternatively, it can also be configured for Profinet Device or a statoc port.
This is possible with restrictions. If no Ethernet based fieldbus is required with exclusive access to the interface, the second Ethernet interface can be set as a normal network interface. However, only IP and netmask can be set as a direct connection with the PC as service and programming interface. If you have a Berghof display controller, the current IP address of the first Ethernet port is shown on screen. The default address is: XX Where XX denotes the last two digits of the device serial number.
X, X is the last digit of the devices serial number. The network mask is always set to Both devices cannot have the same IP address! If the problem occurs that you have a displayless controller where the IP address is no longer known, there are two ways to get access to the controller again. The most common method is the so called Maintenance Mode. Among other things, as long as this mode is active, the controller can be accessed again via the default IP, no matter which IP address was set before.
After a restart, however, the set IP address is active again. The other method is via the Berghof USB update functionality see from 1. The maintenance mode can be compared to the safe mode of Windows. In this mode only a barebone system is started on the plc, the application and other services remain deactivated.
To activate the maintenance mode, the plc has to be turned off and then the following steps have to be performed:. The most convenient method to transfer files manually on the plc is by using FTP. For that the FTP Server must be activated in the plc config s. It is very important to be catious not to change any of the basic directory and file structure on the plc, in the worst case the CODESYS Runtime will not be executed anymore.
Also all files created by the application without a specific filepath will be found here. Over the FTP Program it is then possible to create new sub-directories, to load selected files from the plc or to write new files on the plc. When using the FTP file transfer the transfer-type has to be considered.
For that connect to the plc via FTP s. When the folder "fonts" has been created, fonts have to be stored in it, because with an empty "fonts" folder the target visualization will not find any font and therefore will not display any font. After the restart the newly loaded font file can be seen listed in the Fonts overview in the Webinterface s. The system requires that the file extension of the font file names are in lower case letters, otherwise the system will not recognise the font files when it starts.
The web interface is the web based configuration menu of nearly all Berghof controllers. A web server is running on the plc which allows the use of HTML5 compatible browser to change the configuration of the plc. Depending on the plc model some or all of the following configuration options are available: network settings, sc card, VNC, FTP, clock, user management and more.
It is possible to view the system and plc logs and check the activity of the device. Furthermore firmware updates can be done this through the web interface as well as system resets and starting and stopping of the application on the controller. To reach the web interface of a Berghof plc with a web browser both devices, the development computer and the plc, have to be in the same network.
If this is the case the web interface can be reached by entering the IP address of the plc into a browser and a login screen with the Berghof logo should appear. To change the IP address of a plc, first you have to login into web interface. In the left side menu under Configuration click on the menu entry Network to reach the network settings. Do the same thing with the netmask text field, put the network mask here. Leave the Mode setting on static. Are all changes complete, click on the Save button to save the changes permanently.
The plc has to be restarted for the new IP address to take effect. Common: Common configuration, here the networkname of the plc can be set as well as the DNS Server addresses. In mode, a distinction can be made between:.
Virtual extensions of the eth0 and eth1 network interfaces, which enable a second static IP address to be set for the respective network interface, e. Cannot be activated when Mode ethercat is active on the base interface. This is the the Real-time-clock of the plc, which is also used as the UTC timezone. If timezones are of no relevance inside the application, the time can be changed here directly. After the time change the plc does not have to be rebooted. Additionally it is possible to the a timezone for the time.
The timezone is seen as an offset value to the UTC. The offset of the configured time zone has to be added manually by the programmer. Then select the desired zone from the drop-down list and save the setting with the "Change Timezone" button. The plc does not have to be rebooted. In the VNC menu you can change the resolution and the color depth on the plc. The menu entry Display allows you to change the settings of the build-in display of Display Controllers.
In contrast to the VNC settings of other plc models, there is no resolution to choose. The native resolution of the display will be used which is specified in technical documents of the device.
Brightness: This setting allows changing the display brightness. A reboot is needed to activate the calibration routine on the Dialog Controller.
Follow the instructions on screen. Splash Screen: The splash screen is the image that is shown when the Dialog Controller is turned on and can be changed using this option. The image file must be a PNG file max. Every Berghof controller has an integrated FTP server. However no encrypted sftp connection is possible. Berghof controllers have a number of standard users with different access rights. This is rele-vant for logging into the controller via web interface and FTP.
To protect the controller from unauthorized access, the passwords can be changed in the menu item "User Management". User names cannot be changed. To change a password, click in the text field of the password matching the user and enter his new password. To save the password, click on the symbol with the green arrows in the "Change" column. The password must be changed individually for each user. After that a restart is necessary. Berghof recommends all customers to change the standard passwords after receiving the hardware in order to prevent unauthorized access.
Afterwards the plc has to be rebooted. Following Informations are displayed:. Berghof controllers provide the option in the web interface to perfom updates later on. By that it is easily possible to install a firmware or a license on the controller afterwards. After the archive has been fully transferred, an information overview for the transferred archive and what it includes appears. Never turn off the PLC during the update procedure.
During the update procedure it might happen that the browser loses the connection to the controller, this is no problem just refresh the browser manually and the update procedure will reappear. Afterwards the controller has to be rebooted, for the update to take effect. For the majority of the configuration or when performing an update, the PLC has to be rebooted for the changed to take effect.
In order to not turn off the power every time to perform a reboot, this feature can be found in the web interface of the PLC. But Berghof PLCs also offer the basic functionality for application control over the web interface.
It is possible to start, stop, reset and delete a saved application. Additionally it is possible to only delete the retain memory, to create a backup of the whole application folder and further options. The control interface is divided into four different units. The first unit shows the current runtime state of the application. This setting, once activated, allows running the application from an SD card instead of the internal flash memory.
The application and all needed files will be stored on the SD card. This setting helps if the application gets to big and no longer fits into the internal memory or if an easy swap of a plc is needed. Simply insert the SD card into a new plc, activate this setting and the application starts normally. This feature can only be used with a specially prepared SD card from Berghof.
Normal SD cards from the local electronics store will only be recognized as massstorage device, but not as a system device. However the web interface will remain active and the setting can be disabled. This option is intended for adavanced users only and is for special circumstances only. It is recommended to leave this setting unchecked.. With one glance it is possible to see which application is currently running on the plc:. The following information has to be entered manually into the project information inside the CODESYS application in order for the web interface to display the contents:.
Because of this there is a filesystem present on the controller just like on a PC. All relevant files needed to run an application on the plc are stored in one folder, the so called application folder. The web interface offers the possibility to display all files which are located in the application folder even if they are located in sub-folders. Additionally it is possible to click on each of those files and download them through the browser and store them locally on a PC or Laptop for example.
However it is not possible to upload a file to the plc this way, this is done differently s. Berghof PLCs have functionality to create a backup image from a running application. This image can be used to restore the application back to a running state in case an error should appear or to equip multiple with the same application. The restore can be performed either over the Berghof USB update script s. Depending on the size of the application folder this process may take from several seconds up to several minutes.
Please consider that the saved application on the plc will be overwritten. When files are in the application folder and in the image, the image file will overwrite the existing files without prompt! Files tha are in the application folder but not in the image will be kept, but might be without any functionality depending on the application.
After the upload of the backup image is finished a restart must be performed for the changes to take effect. When the PLC is stopped, the "Clean folder" button can be used to initiate the deletion process.
The menu is divided into two sub units. It is not possible to change or delete the system fonts. Berghof PLCs offer different diagnose functionilaty for the whole plc system over the web interface. As all loggings are displayed in Linux-format it might be difficult for unexperienced users to understand these logs. Therefore the plc offers the option to create an image of all the relevant logs in case of an error. This log image can then be sent to Berghof for further analysis.
Is there an error, where e. Again, the information is displayed Linux-format. You can read information like the MAC-address, configured IP, netmask as well as received and transmitted bytes, etc. You can read information like the BUS-Status, configured Baudrate, as well as received and transmitted bytes, etc. The relevant information for the user is the available flash memory of the plc, which can be seen in the picture inside the green frame. At Gardena, the renowned manufacturer of intelligent systems for garden irrigation and maintenance, the "eChiller", which recently won an award from the European Commission, has proven itself over the past year to be highly energy efficient and low maintenance.
