Kozma10 Posts: 12 Rating: (0)	Hello I would ask for help with programming. I want to shift an array of data when new data comes along. I made a DB with an array type. In STL, I want to write that the signal comes and enters the first place, and then when the next signal comes, the data on the first comes in the second place and the new one comes on the first. I don’t want to do it with SFC20 because there will be a lot of areas. Pictured is the DB stricture the way I want it. Thanks Attachment Névtelen.png (557 Downloads)

If you want the SCL , you can retrieve that by opening the OB1 in STL editor. I hope it helps, hdhosseini

I think to do the same with LAD and SFC20 , that solution is not professional and perfect IMHO.
