T.ON DELAY PLC PROGRAMMING USING B&R AUTOMATION STUDIO

I've been trying to program a PLC using the T.ON delay function(PLC) in B&R automation studio to generate the waveform in the picture. I first started off by trying light an LED every 1 second but initializing a delay for multiple LED's is some how confusing me. I'm working on research but first I have to understand this simulation before I can move forward. Any tips on what I can do to my design to make the delay waveform using T.ON be generated? Say for example every after 5 seconds?
