a super-quick question on SFC programming in OpenPLC.
As far as I know, in the standard 611313 it is assumed that every phase in a SFC graph has 2 variables associated, a phase marker (i.e. step.X) and a phase timer (i.e. step.T).
However, if I try to use the latter I get some compilation errors (while, if I substitute it with a dummy time variable, everything woks flawlessly).
EDIT - actually using it in inline transitions works, but the example below does not (?)
