The C-more HMI (human machine interface) is one of the best values in industrial HMI. Not only do you get competitive pricing but the ease of setup and use will save you even more.
In this video, we show how to capture HMI Screen images so that you can evaluate or inform users of issues or improvements to your HMI or control system.
This video is part of the C-more HMI setup videos that give direction on how to set up, use and maintain your industrial HMI.

In the C-more HMI, you might need to capture the screen so you can evaluate what is happening in your process. So, I have this screen that is detailing the running state of my process and I have created this pushbutton and I want to use this to trigger capturing my screen. I applied this internal discrete tag that is in my C-more HMI to this pushbutton. To create the screen capture action, go into your Event Manager Database from here. Select to add an event. Give this event a name. Apply the tag that you want to trigger the screen capture event with and of course, I am using the tag that I applied to my pushbutton. Come down here and select the default alarm action and delete it. Select to add an action and then select the Screen Capture action. You can select to capture the current screen that is being displayed or select some other screen. I am wanting to capture my running status screen, which is screen 3, so, I will select other screen and select screen 3. By default, screen captures get saved to the log folder under the SD1 card. If you would like to change this storage location, open up your Panel Manager and change this setting. If you would like to add some organization for these files, you can place a subfolder name here and then give this screen capture file a name. If you want to store multiples of these screen captures, for later evaluation, you will need to select this option. If you do not select this option, it will just overwrite the previous screen capture. If you do select this option, it will append the file name with the time at which the screen was captured. Last thing here, is that you can set the image quality of the capture. By using this you will be able to save more storage space on your drive. I find the default works fine for me. It doesn’t eat up too much storage space. Typical a file size for a 12-inch screen at 60% is around 50 Kilobytes. Once you have that set up select add then select close. And here is the screen capture event we just created. To show an example of this operation, I will run the simulate in the C-more HMI. Select the panel size you want to display on. I am going to navigate to screen 3 and hit my screen capture pushbutton a few times. Now, I am going to open up my virtual SD1 card location from here and you can see the screen captures. Quick and easy. C-more keeps proving why it is the best value in HMIs. If you have any questions on this process, please feel free to comment below or call into our Free technical support department.
