How to get into the WBMHow to get into the WBM

Establishing a connection to the Web-based Management (WBM):

  • Open a web browser on your computer.
  • In the address field, enter the URL https://<IP-address-of-the-controller>/wbm,
    for example: https://192.168.1.10/wbm.

For further information, see WBM.

PROFINET page

On the PROFINET® page, you can view information on the controller and the connected PROFINET® devices.

Note: The following description sometimes refers only to firmware 2022.0 LTS where PROFINET® diagnostics got some new features. To fully benefit from the PROFINET® diagnosis in WBM, use both firmware and PLCnext Engineer releases 2022.0 LTS or higher.

From the 2022.0 LTS release on, the vendor-specific PROFINET® alarm error codes are downloaded to the controller by means of PLCnext Engineer, along with the corresponding plain texts for the error codes. 

The vendor-specific PROFINET® error codes and the corresponding plain texts can be imported into PLCnext Engineer by means of FDCML files (Phoenix Contact devices) or by GSDML files (other vendors).  

For additional information on interpreting the raw diagnostic code, refer to PROFINET diagnostic code in WBM.

Overview tab

On the Overview tab, you will find information on the current PROFINET® function of the controller and its IP settings.

Status area

In the Status area, you can see whether the controller is currently being used as a PROFINET® controller and/or a PROFINET® device.

Controller Details area

The current IP settings of the controller are displayed in the Controller Details area.

Diagnostic information on the connected PROFINET® devices is available on the Device List tab.

Device List tab

The Device List tab provides an overview of the configured PROFINET® devices.

The overview contains the device names of the PROFINET® devices, the current IP settings, as well as the diagnostic state and code.

 

Diagnostic state Description
OK     No error
Warning A warning occurred, e.g., “Maintenance Required”, “Maintenance Demanded”, and “Diagnosis available”.
Error
  • A PROFINET® bus error occurred.

From firmware 2022.0 LTS on:

  • A PROFINET® bus error occurred.
  • A module error occurred (i.e. in the backplane of a PROFINET® device). 
  • AR has not been established (no connection is displayed as status for the respective AR).
AR deactivated AR is deactivated. Diagnosis is not possible.
(From 2022.0 LTS, AR can be deactivated via the AR_MGT function block in PLCnext Engineer.)
From firmware 2022.0 LTS:

Opening WBM of a PROFINET® device

Some PROFINET® devices feature their own web-based management (WBM). You can open WBM of a connected PROFINET® device via a link on the Device List tab.

  • In the Device Name column, click on the PROFINET® device whose WBM you want to open.

The WBM of the PROFINET® device is opened in the web browser in a new tab.

Opening the Device Information view

In the Device Information view, you will find certain general information, the current IP settings as well as diagnostic information for each connected PROFINET® device. 

  • In the Details column, click on the WBM_details.png button.

The Device Information view opens.

From firmware 2022.0 LTS on, the Device Information view additionally contains details on diagnostic information of the modules located in the backplane of the respective PROFINET® device. This information is displayed under Channel Diagnosis in the Device Information view (see third example below). 

Device Information in case of no connection to a PROFINET device:
Device Information in case the AR is deactivated:
Device Information in case of an error in the backplane of a PROFINET device:

Update frequency for diagnostic data

Diagnostic data is updated with an update frequency of 1/s. The following information is updated:

  • Device List: The Device List can be recomposed, e.g., after changing and updating the PLCnext Engineer project.
  • Diagnostic data:
    • Change of connection status of the PROFINET® devices
    • Diagnostic state of the PROFINET® devices

Fast path to the Tree View

By clicking on the link inside the tree node column it is possible to swiftly change to the Tree View tab. 

Tree View tab

The Tree View tab provides an overview of the configured PROFINET® devices. The overview contains the device names of the PROFINET® devices, their current IP settings, as well as the diagnostic state of the devices and modules.

Tree View

The PROFINET® Tree View contains all the PROFINET® devices from the Device List.

  • Click [+] or [‒] to open or close the next level of the Tree View.

The following icons provide information on the current diagnostic state of the PROFINET® device:

OK     Normal operation state.
Warning     Maintenance is required according to the PROFINET® specification.
Urgent Warning     Maintenance is urgently required according to the PROFINET® specification.
Error An error has occurred which needs to be resolved immediately.
AR Deactivated AR is deactivated, e.g. via function block AR_MGT in PLCnext Engineer (from firmware 2022.0 LTS).
Module Difference There is a physically another module in the backplane than in the configuration of the project (see Module difference).  
No Connection AR could not be established.
No Information In case of a deactivated or not established AR there is no information available of the actual physical configuration in the backplane of the respective PROFINET® device.

The Tree View provides the following information:

Controller level

The following information is available on the PROFINET® controller level:

  • Controller designation
  • IP Address of the controller
  • Number of PROFINET® devices

By clicking on the controller icon you can access the Device Information view.

Station level

The following information on the PROFINET® devices is available on Station level:

  • Station name
  • IP address
  • Number of connected modules

If you click on the station icon, a Device Information window will open, containing further information. In this example there is power fail of module, visualized by the error code and the corresponding plain text in the Channel Diagnosis section.

If the GSDML (or FDCML) file does not contain a plain text for the corresponding error code, a following message "Manufacturer specific” (3400(hex)) would be displayed.

If the GSDML (or FDCML) file contains a vendor-specific help text in addition to the plain text, that vendor-specific help text will be displayed in the Status Details as in the following example:

Module level

The following information is available on the PROFINET® device module level:

  • Module designation
  • Number of submodules

If you click on the module icon, a Module Information window will open containing information on the upper-level PROFINET® device the module is configured to, slot number, module type and number of submodules/channels. If applicable, an error code with corresponding plain text of the channel diagnosis will be displayed as well.

Submodule level

The following information is available on the submodule level of the PROFINET® device modules:

  • Submodule designation
If you click on the module icon, a Submodule Information window will open containing information on the upper-level PROFINET® device and module the submodule is configured to, the subslot number and, if applicable, an error code with correspondig plain text of the channel diagnosis.

Module difference

If there is physically another module in the backplane than in the project configuration, a specific diagnosis is displayed in the WBM.

In this case, the Tree view will display the following:

In case of a wrong module, the Submodule Information view displays the following:

In case a module is configured in PLCnext Engineer but is physically not available in the backplane, the Module Information view displays the following:

With firmware version 2022.6 or newer:

In case a module is configured in PLCnext Engineer but physically a different module is installed, the Module Information view displays Wrong Module and the module ID of the physically installed module:
