The PLC application has the following structure:
CALL FC 9 //SYNCHRON_RESET
ADR :=256 //Module address
TIMER_NR :=T8 //Delay time for CP
ANL :=M3.0 //CPU start complete
NULL :=M3.1 //Internal flag
RESET :=M3.2 //Initialize reset at CP
STEUERB_S:=DB10.DBB260 //Control bits for Send
STEUERB_R:=DB11.DBB108 //Control bits for Receive
U
M 3.0 //as long as Synchron active
BEB //no processing of CP
CALL FC
