Hello Siemens Community, I have been having a small hiccup/problem with my project. Everything is working flawlessly but the I/O Field element is giving me a headache. So here is what happens: This I/O Field is supposed to display value from my thermocoupler PT1000 and It does it works and all, But to get the value to display on my HMI/RT in my I/O field, I have to go back a screen and go back again on the screen where the I/O field is to make it update/display the proper value, So lets say. I am putting out 170 Celsius via my PT1000 and It shows up in my watch table with the proper value but on the HMI/RT the value in the I/O field retains the same until I change the screens, So like I said, I have to go to another screen then go back to the screen with the I/O Field to make the value display normally. Note that there is proper connectiong between PLC and the HMI/RT as the RT is reading Digital I/O and Analog Output Force just fine. I will add 2 screenshots with Before and After changing the screen and updating value. Additional Info: Analog Input Card I use: 6ES7 134-6JD00-0CA1 CPU I use: 6ES7 510-1DJ01-0AB0 I use TIA Portal V16 Update 5, WinCC Professional V16 Update 5 AttachmentScreenshot.zip (91 Downloads) |

Hi Tomo7, Please check how you are updating the value of the tag in the Runtime -> TIA V17 - Updating the Tag Value in Runtime If 'On demand' is configured, the behavior you are experiencing is normal, and I would recommend setting it to 'Cyclic in operation' or 'Cyclic continuous' (only for tags that really need it). I hope that helps! |
A rating will be well appreciated. |

Hey itafusna, Tags were set to Cyclic in Operation with 500ms cycle, I will check with Cyclic continuous if that fixes the problem as soon as I get back to the plant. Thanks! |

Hello Tomo7 If the Tags are in Cyclic operationthen this should be correct. It is not neccesary to set them to cyclic continous. Check please with cross reference if these Tags are used in a recipe, this could also cuase such a behaviour of not updating. And I would recommend doing a Reset of the Runtime data with: https://support.industry.siemens.com/cs/de/en/view/109778709 Bye Murof |
