Upgrade to release 1.8.51

[DanT]

Hi;

 

I upgraded my 10 inch UniStream to the new release 1.8.51 and have a couple of things to share :

 

The upgrade in OS in the PLC had a problem and restart got stuck in Initialization.

      I got mine recovered and let support know what I did,

      Maybe support should inform us the "better" way to do it.

 

In my program, I have an Imbedded Data Table with data preloaded- a lookup table.

   During the upgrade from old version to new version rebuild, the data table was either wiped or not rebuilt.

   I ended up going to another computer with the older UniLogic, saving the data table to an Excel file and then importing  the file into the upgraded project.

 

   Just to note also :  imbedded data  tables with fixed data are not automatically downloaded to the PLC during a download. They have to be manually loaded.

Dan I had a small issue upgrading to the new firmware too. Some graphics were not appearing on the plc but were in the project. I downloaded a blank project and then reinstalled the new firmware-problem solved. Not sure what the "better way" is but this is what worked for me

forgot to mention I had the same discovery about the data tables. Thankfully I had the older Unilogic and project on another computer.

Hi;

 

I did have a Blank program in the PLC before I did the Upgrade - Found that our a few versions ago, best to download a blank program into the PLC and recycle power before doing the upgrade.

 

And Yes, having the older version of Univision available on another computer is very handy during the process.
