Fix bug in SFC generated code. Action state was declared in the list of variables to debug, but wasn't stored using structure with flags. This error had side effects that makes Beremiz debug crash.
FUNCTION WEIGH : WORD (* BCD encoded *)
VAR_INPUT (* "EN" input is used to indicate "scale ready" *)
weigh_command : BOOL;
gross_weight : WORD ; (* BCD encoded *)
tare_weight : INT ;
END_VAR
(* Function Body *)
IF weigh_command THEN
WEIGH := INT_TO_BCD (BCD_TO_INT(gross_weight) - tare_weight);
END_IF ;
END_FUNCTION (* Implicit "ENO" *)
