Hi I uploaded tia portal v13 project from ET200S cpu, the uploaded project now is without tags. i asked engineers and the answer was that: during project downloading ,the tags stay in original project file, not downloaded to s7 300/400 families CPUs. Now all the tag names are useless in this project as they are not downloaded to cpu. So will it be problem for compile and re-download the uploaded project back to cpu? Will it be OK for hmi to communicate with plc using absolute addressing only? I don't have the original project files of both HMI and PLC Thanks -

Hi, Say I have a custom AOI with the tag 'CV323' and it is declared as my custom datatype. Is it possible to use that tag as a String inside my AOI so I can make concatenations like 'CV323 ON' and 'CV323 OFF' that are available to an HMI? I know I can declare a string with a near similar name as an in/out and type it in but would prefer just to use the AOI name. Thanks in advance. -
Hi all Thank you all for your supporting and trying to help. I managed to get the plc password, just uploaded the plc project and re-download it, now it's showing normal temperature reading (about 20C) Really I would like to know the reason of this disturb, but as it's running, I'm happy. Thank you

H0U, H1U and H2U are not Mitsubishi, it is Inovance, also as USB cable. -
@TonyBB Try this sample program to see if it does what you are looking for. Once a user has logged in successfully, it will show a popup with the user name and then it will automatically close after a set amount of time. Just build and run in simulation. I created some general user levels that you can login with to test the pop-up notification. HMI_Popup.smc2 -
Q Series is not end of life, no discontinuation of it has been announced. But yes, upgrading to the iQ-R is the proper solution. And for the OP, there is even a rack for the iQ-R Series that allows connection of the older Q Series modules. -
I am not aware of a way to make a confirmation dialog like you indicate. Perhaps in a global script you can look for the logged in user name or security level to change.

If the product is old and out of support, then it's old and out of support. No magic we can do to help. Keep in mind DOS based software is likely 30 or more years old. You can't just keep using these legacy devices forever.

Perhaps your spare PLC is bad, because you said you can connect to others and your settings are all correct. So not sure what else it could be besides a failed PLC.
