Program example
• The following program stores 10-word data, which are stored in the devices starting from D0, to the devices starting from
D1000 of the number 1 local station connected to the master module mounted on the I/O numbers from X/Y40 to X/Y5F
when X0 turns ON.
(When the refresh device of the link special register (SW) is set to SW0.)
[Structured ladder/FBD]
[ST]
IF((X0=TRUE)
&(Var_Flag_Exe=FALSE) (* Execution flag *)
&(SW80.0=FALSE))THEN (* Data link status of station number 1 *)
MOV(TRUE, 1, Var_ControlData[1]); (* Sets station number *)
MOV(TRUE, H0405, Var_ControlData[2]); (* Sets access code and attribute code *)
MOV(TRUE, 1000, Var_ControlData[3]); (* Sets device number *)
MOV(TRUE, 10, Var_ControlData[4]); (* Sets number of read points *)
G_RIWT(TRUE, H04, Var_ControlData, D0, Var_Result); (* Performs writing *)
SET(TRUE, Var_Flag_Exe); (* Turns execution flag ON *)
END_IF;
IF(Var_Result[0]=TRUE)THEN (* Execution finished *)
IF(Var_Result[1]=FALSE)THEN (* Normal completion *)
ELSE (* Error completion *)
END_IF;
RST(TRUE, Var_Flag_Exe); (* Turns execution flag OFF *)
END_IF;
