Question

Why is it that when I use online editing to delete instructions that cause an output on Programmable Controllers to be turned ON, the output does not turn OFF?

Answer

If you use the online editor to delete a bit that is ON, the bit will remain ON. This is because the program needed to turn OFF the bit has been removed.
