L #c_Max_Bags SBiB: T #t_n_i //Stuff L #c_Max_Bags L #t_n_i -I T #t_n_for // cycle from the 1st to the last T "T1" L #Bag[#t_n_for].Idx L #Bag["T1"].Idx L P##t_n_i LAR2 L #Bag[AR2,P#0.0].PLC_Idx L #Bag[1].Idx L 0 ==I JCN SBiBN L #t_Index T #Bag[1].Idx L 1 = #Bag[1].Trigger SBiBN: L #t_n_i LOOP SBiB I can´t manage to cycle the array! I'm not very good with STL and even less with Pointers. I've added a Picture with The TIA project to help visualize the erros. Attachment Annotation 2024-05-15 141413.png (209 Downloads)

	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine

I'm not using the source method because it leaves the code too complex, and I need it to be understood by the commissioning team. Now I am learning how to properly use pointers.
