Program example
• The following program initializes the parameters of buffer memory and those of flash ROM when X3C turns ON.
[Structured ladder/FBD]
[ST]
PLS(X3C, Var_Flag_Inst); (* Parameter initialization instruction pulse *)
IF((Var_Flag_Inst=TRUE)&(X0C=FALSE))THEN
SET(TRUE, Var_Flag_Mem); (* Turns parameter initialization instruction memory ON *)
END_IF;
IF((Var_Flag_Mem=TRUE)&(Y0=FALSE))THEN
OUT_T(TRUE, TC0, 2); (* Waits output of programmable controller ready for the positioning module *)
END_IF;
IF(TS0=TRUE)THEN (* Parameter initialization instruction memory ON *)
ZP_PINIT(TRUE, "00", Var_ControlData, Var_Result); (* Performs initialization of parameters *)
IF((Var_Result[0]=TRUE)&(Var_Result[1]=FALSE))THEN
RST(TRUE, Var_Flag_Mem); (* Turns parameter initialization instruction memory OFF *)
END_IF;
END_IF;
