Set Up Signals for the Connector

Abstract

Check out this article to learn more details on how to configure and customise your i4SCADA Signals in just a few easy steps!

After defining the connector, you can set up the connector signals inside Studio using the Connector view. This view is active when a connector node is selected in the tree menu. The Connectors view displays the signal groups containing the available signals for the selected connector. The Connector view is identical for all the connectors available in WEBfactory Studio.

When opening the Connector view for the first time, no signal group will be listed. The signal groups can be either created manually here or can be created automatically when importing connector signals. The following signal group properties are listed in the Connector view:

  • Active - if the Active check-box is marked, the signal group is taken into account when the i4SCADA Server is started.

  • Name - signal group name.

  • Description - optional description.

  • Read Write Mode - read/write permissions, applied to all the signals inside the group. Can be:

    • Read - the group's signals can only be read

    • Write - the group's signals can only be updated with new values, requiring a user with the appropriate rights.

    • Write, Read - the group's signals can be read and updated with new values, requiring a user with the appropriate rights. 

    • Write (unsecure) - the group's signals can only be updated with new values, without requiring a user login

    • Write, Read (unsecure) - the group's signals can be read and updated with new values, , without requiring a user login

  • Update Time (ms) - the time interval for updating the signals data.

  • Load Balancing - if activated, the system will process only signals which are used in visualizations or in alarm conditions. If disabled, all available signals will be processed.

In order to be able to write signal values, a registered user must have access to the appropriate write group. 

The signals can be defined in multiple ways: by browsing the available signals in the connector, by defining new signals inside the signal group or by importing saved signals inside the signal group.

Any defined signal is visible in the signals view. This view displays all the available signal information inside its grid. The same signal information is available for editing in the 

Browsing the Connector
  1. Right-click on the connector node in the tree menu and select Browse Connector. The Browse Connector dialog allows the user to select one or more available signals for the current connector and import them in the WEBfactory Studio and place them into the selected signal group.

  2. Select the desired signals and the destination signal group. If no signal group is defined, you can create a new one by typing the name of the new signal group directly into the Destination group field.

  3. Click Add once the signals and destination signal group are selected. The signals will be imported in i4SCADA Studio.

Defining New Signals
  1. To create new signals inside i4SCADA Studio, navigate to the signals view by selecting the signal group node in the tree menu.

  2. Right-click either on the signal group node or in the signals view and select New Signal.

  3. A new signal will be added in the selected signal group. The signal properties can be set using the Signals Details panel at the bottom of the signals view.

Importing Saved Signals
  1. To import saved signals in i4SCADA Studio, right-click either on the signal group node or in the signals view and select Import Signals.

  2. Select the XML file containing the saved signals and click Open. The signals will be imported in the selected signal group, with the same settings as they were when exported.

Description

Expand / Collapse

Expands / Collapses the Server view menu item, hiding or displaying the available connectors.

New Group

Allows the user to add a new signal group to the connector.

Delete

Deletes the selected connector.

Browse Connector

Opens the Browse Connector dialog, allowing the user to add the signals available to the connector to the Studio project.

Validate Signals

Opens the Validate Signals dialog, allowing the user to view the invalid or unused signals. 

Refresh

Reloads the list of connectors.

Main panel contextual menu

Right-clicking on the signal groups listed in the main panel while the a connector is selected will open the contextual menu. The contextual menu allows the user to edit the cell from where the contextual menu was opened, set the read/write mode for the signal group, set the update time for the signal group.

  • Read: Signal variable process data can only be read.

  • Write: Process values can be written into signal variables.

  • Read and write: Process values can be read and written into signal variables.

  • Write (unprotected): Process data can be written into signal variables without user login.

  • Read and write (unprotected): Process data can be read and written into signal variables without user login.

New Group

Create a new signal group.

Delete

Delete a signal group.

Refresh

Update the current view.

Important

The contextual menu of the SIMATIC connector in the Signals tree menu provides different options!

Also, the SIMATIC Connector configuration may be copied from one Server to another. To organize this action, copy all files from %ProgramData%\WEBfactory\SimaticConnector from the source server to the destination server.
