Posted 30 Apr 2020 (edited) You'll need to run Logicmaster on an older computer running nothing newer than XP. Best success will be on a machine with real serial port. I've not had much success uploading/downloading with Logicmaster through a USB/serial converter. Once you have Logicmaster running you can connect to any of the three serial ports. The two ports with cables connected in your picture are RS485. The unconnected port 1 I RS232. Are you sure the program in the PLC was created using Logicmaster? If it was created with VersaPro or Proficy Machine Edition, Logicmaster won't be able to open it. Edited 30 Apr 2020 by Steve Bailey Share this post Link to post Share on other sites

Posted 30 Apr 2020 Those files are backup files created by Logicmaster. Here's a method to use them. First, using Logicmaster, create a new folder using the correct name. Save it. Then go into edit mode and when Logicmaster asks if you want to make a backup, answer 'yes'. Add a rung of logic. It doesn't matter what you put in it. It will be overwritten when you restore from the backup files. Save your edits and exit Logicmaster. Now locate the project folder with Windows Explorer. The normal location is C:\LM90\Myfolder. You should also see C:\LM90\myfolder\Backup. That 'Backup' directory was created by Logicmaster. Copy and paste the PKA, PKC, PKL, PKO and PKR files into the C:\LM90\myfolder\Backup directory. Let the paste procedure overwrite the existing files. Reopen Logicmaster, launch your project and use Logicmaster's restore procedure. 1 person likes this Share this post Link to post Share on other sites
