Occasional HMI Mismatch

Recommended Posts

I am still experiencing occasional HMI mismatches. The application has been created under Windows 7 and I have upgraded to Unilogic 1.7.62. I also upgraded the OS on my 10" Unistream to the current firmware. This problem happened before the upgrades and is still happening on occasion.

The HMI mismatch message is generally displayed when the firmware and application version do not match. After the firmware was updated did you re-download the project in UniLogic 1.7.62?

I too get the HMI mismatch error occasionally. It has been a common re-occurrence on all 3 Unistream panels that I have programmed. The first time it usually occurs is when upgrading the software from the factory version to the current version. This first mis-match is to be expected since the hardware usually ships with a version that is outdated by the time the hardware gets to the user. Once the hardware is updated, this seems to go away as it should but after downloaded a new program several times, occasionally, the HMI mis-match error reoccurs. I have almost always simply downloaded the same program again and the error went away. Please note that this process had nothing to do with upgrading the HMI software to make the error go away, I simply re-initiated the same program download that occurred just before the mis-match error. For some reason this process seems to fix the problem.

 

I may be wrong about this, but it seems that when the mis-match error shows up after the initial out-of-the-box software upgrade occurs, it is somewhat of a phantom error and is easily cancelled out by repeating the download.

My issue with the mismatches was appartently due to a lot of binary images that would change state at the same time. The images themselves were resized in Unilogic and were quite different than the original image pixel sizes. Unitronics support had me resize the images to the intended size of my application and load them.

 

Ofir, if your listening..........thus far.......HMI mismatch has not occurred since those changes. Thanks!

I found the same thing, tried to upload an example program, had to upgrade the firmware, then it wouldnt let me download any new programs until the example program I tried to upload previously was downloaded........
