Hi all, what is the purpose of BR bit in status bit. I have program who using SAVE instruction. I see in help file SAVE instruction put RLO in BR (bit register). How do you use it in your code? thanks

Using it very simple indeed. 1. When writing a Function (FC) or FunctionBlock (FB) SAVE instruction at the end of the block, for example: A #Some_Variable // copy Some_Variable value to a BR bit SAVE 2. When calling this FC or FB, do it in FBD language. You will see ENO output of this block. This is the signal, containing your saved BR You can feed this output to any other BOOL input (another FC or FB, memory, etc.) Best Regards!
