How to load variables from Quantum Concept PLC?

[leofarhan]

Hi Guys,

I have to troubleshoot a program in Quantum Concept PLC, I have an old program which is not equal to the one in the PLC. As you know if IEC Upload info check box is not clicked, you will not be able to upload PLC program.

Since I have old program so I can guess the issue, but for that I need to monitor the variables/unlocated variables. I have checked the variables with memory addresses and I'm near to solve this puzzle. But I need to read the value of other variables/unlocated as well to solve it completely.

If anyone have a trick or advise, please be generous to share it.

Best Regards
