The Enhanced or Basic security feature can indeed be used to control object visibility, as select objects can be hidden for different access levels. Object visibility an also be controlled based on the status of a bit, which can be configured on the Security tab in the object attributes window.
When first logging in to WebView or EasyWeb 2.0 you may get a message warning that the website’s certificate could not be verified. The exact wording and look of the message will depend on the browser you are using, but it will be something to the effect of: This is because the connection to…
In order to display the privilege of the current user, write a value of “13” to display privilege per Username or “14” to display privilege per User ID. Make sure either the username or user ID are loaded into the Security Control registers before sending the command to the command register.
If you change the VNC password in the HMI System Settings window but it still retains the old password, it is because the project that is running in the HMI had the “Password from project” option checked in the System Parameters > Remote tab. When this option is checked, it overrides the password that is…

The security feature in the software contains many tools to restrict access to HMI screens, objects and functions. There are tools to manage passwords at run time, add users, update passwords and access levels, and create temporary users. Refer to the security chapter in the EBPro Programming Manual for a complete discussion of the security…
Yes, you can replace the default startup screen on an HMI with one of your own choosing. The graphic file must be in a bitmap format (*.bmp). For best results, size the graphic so that it is the same size as the HMI screen in pixels. You can download your custom startup screen along with…
The arrow icon that appears (by default) in the bottom right corner of the HMI screen provides access to the HMI’s local settings. The default password (111111) should be changed to restrict local access to these settings. This password protects the VNC password, enable / disable option, project upload / download passwords and many other…
Yes, live video can be viewed directly on select Advanced and cMT HMI products. Video input options are IP (Ethernet) cameras and USB cameras. Video cannot be recorded, but still images may be captured from the live video. Images are captured via a bit trigger, making this feature ideal for capturing production or security events…
Object-level security in EBPro allows the programmer to show or hide objects on the screen, or control write-access to objects. Object-level security can be either via an Interlock function (the object is hidden unless a specified bit is set or clear) or via a user access level (only users with that level of security access…
Yes, select models allow users to view a live video web stream on a remote computer from a USB video camera attached to the HMI. This is useful for monitoring a process or area of the manufacturing floor that is difficult to see from the operator’s position.
