Posted 18 May 2021 Hello Im trying to read from my PLC but i cannot see the program file. However, if i try to compare it using other file program, i could see the program file. Is their any restriction in my software? Share this post Link to post Share on other sites
Posted 18 May 2021 Are you using a licensed version? I believe the demo versions do not allow online communications. Share this post Link to post Share on other sites
Posted 18 May 2021 Yes Im using licensed version. I forgot to mention, during READ, I can only see the 'Parameter's and 'Device Comment' but no 'Program file'. Share this post Link to post Share on other sites
Posted 19 May 2021 If you're trying to read from PLC and not seeing a program file, likely there is no source code information you can retrieve from the PLC. It may not be showing the programs if they are password protected, but I would expect it to show them and ask for password before transfer. What type of PLC are we talking about here?

Posted 21 May 2021 On the dialog where you read from the controller, it may have a drop down for multiple drives. I know Q CPUs had an internal ROM backup drive, maybe the read is looking at the wrong drive. Can't be more specific, sorry, haven't touched one in 8 years. 1 person likes this Share this post Link to post Share on other sites
