What do the Step and Seq block functions in PLC AC 70
Guys, I'm doing a project in ABB, I have just 1 year of experience so I don´t know a few basic things about this PLCs, Reading the document (the project I'm doing) I realize that there is two blocks functions called Step and Seq in BFD, I don´t know what specifically this block do. Could Someone help, and sorry for the basic question.
The arguments for the functions are :
Seq(5000,1,1,0,0)
Step(1,2,0,0,0,0)
The arguments for the functions are :
Seq(5000,1,1,0,0)
Step(1,2,0,0,0,0)

They are used to create a SFC (sequential function chart) The Seq block is the start of the sequence and the step represents each step in the sequence.
