I have read that there are two ways to get SFC retain:

  1. Declare all Stepnames used in SFC as RETAIN variable
  2. Define your POU istead of a PROGRAM as FUNCTION BLOCK and declare the FUNCTION BLOCK as RETAIN

I have tested nr. 2 and it works fine, but I can't get nr. 1 to work.
Where and how do I declare the stepname?
Is it StepName: BOOL; or what?
