Hello, I have this exact same issue, exact same issue except I always Compile -----> Software (rebuild all) before saving and downloading Software (download all). I am using the following:
My I/O Field is set for the following:
I can enter the value into the I/O field and it accepts the value, but will not write the value to the DB. It keeps the same value when changing pages and coming back to the page. I have checked the HMI tag link to the PLC tag link and deleted/added back I/O field but still cannot write to the DB. I have also check that there is full access to the HMI Any help would be greatly appreciated! Update 6/2/20: Adding the following software information that is being used to assist anyone that may have a solution: The original issue is that I/O fields are created and will not write to the PLC working memory or any DB. Values are entered into the fields during runtime, values are accepted and stay in the I/O field on the HMI, but never are written to the PLC.

Hello check if the Tag you write in through the IO field is NOT used in a Recipe and if everything looks OK then try to reset the temporary files: https://support.industry.siemens.com/cs/de/en/view/109778709 Bye Murof |
