Hello surea; Start by comparing the element in your picture to the attached screenshot, taken from the System and Standard functions manual. https://support.industry.siemens.com/cs/fr/en/view/109751826 You agree that the variables are the same? These are the local variables for OB1, the main Program Cycle organisation block. These are used by the CPU's OS to interface with the OB1, and give the programmer some tools to collect information. For example the variable OB1_PREV_CYCLE contains the duration of the last scan cycle of the CPU, in ms. So, what are you asking, exactly? Do you want to know how these parameters came to be shown on the screen? I have no idea, your screenshot is not very expandable and we lose a lot of information when we try to blow it up, and we cannot tell what exactly you were doing in that screen. It would be a lot easier for us if you used computer tools to grab a screenshot instead of a camera or smartphone.You could: - press the PRNTSCREEN key on your keyboard, then paste the image in Paint; use Select and Crop tools to restrict the size of the image. -download freeware, such as PicPICK, that do pretty much the same, but in a single software. The jpegs produced with these tools can be expanded in much higher resolutions, so we can examine them in better details. Hope this helps, Daniel Chartier |
