The initial value of #Valoop1 is 0. BTW the blocks are not optimized. Thank. Hi Omer, I know this works for S7-300/400, but I don't think it is possible for S7-1200/1500. I think you have to use PEEK, POKE in that case. For S7-300/400 the correct syntax is; %DB6.DB(#VaLoop1), not "DBB". Kind regards, Jens
	Keep it simple and on-topic. A simple straight-to-the-point answer is often of more quality than a complicated one.
