Program Example
The following program writes the parameters, positioning data, and block start data stored in
buffer memory to the flash ROM when X3D turns ON.
[Structured ladder]
[ST]
PLS(X3D, Var_Flag_Inst);
IF((Var_Flag_Inst=TRUE)&(X0C=FALSE))THEN
SET(TRUE, Var_Flag_Mem);
END_IF;
IF((Var_Flag_Mem=TRUE)&(Y0=FALSE))THEN
OUT_T(TRUE, TC1, 2);
END_IF;
IF(TS1=TRUE)THEN
ZP_PFWRT(TRUE, "00", Var_ControlData, Var_Result);
IF((Var_Result[0]=TRUE)&(Var_Result[1]=FALSE))THEN
RST(TRUE, Var_Flag_Mem);
END_IF;
END_IF;
