Not quite. You need to select the properties and not the events. properties --> Ouput/Input --> Output Value --> Dynamic Check the trigger and script and change TAG_VALUE to the name of your external tag for this example to work Attachmentxmpl.zip (213 Downloads) |

Its not quite correct. I have changed it so that "Actual_TT44" is your external or PLC tag and "Reading_maxTT44" is your internal tag to store the highest value. I have used the tag upon change for the trigger, you need to decide based on your environment what you need to use. I have attached a new example pdl as well. Your Graphics Designer code should look like this. #include "apdefap.h" Your Global Script code should look like this. Remember to add a trigger to make the script run and that Global Script Runtime is selected in the Startup properties in WinCC Explore. If not your global script wont run. #include "apdefap.h" int gscAction( void ) if(GetTagFloat("Actual_TT44") >GetTagFloat("Reading_maxTT44")) AttachmentMaxValue.zip (153 Downloads) |

Thanks Crompton it's working. your C-script for the max reading is running. I have attache the snapshot & the wincc.pdl. now I can reading the max value but still there is one issue as Mike mention the max value is disappear if I close window ,even I use the global script.(check script.png) in the attached file. you can see snapshot2.png value & snapshot3.png value. and the maxTT44 tags is not updated even the max value has change. in the attached file you can find the snapshot for the script which I add it in the global script and in the pdl graphics designer.
