Program example
• The following program reads out the offset/gain value of the A/D converter module mounted on the I/O numbers from X/Y00
to X/Y0F when the flag turns ON.
[Structured ladder/FBD]
[ST]
IF(Var_Flag_Inst=TRUE)THEN (* Instruction flag ON *)
MOV(TRUE,0,Var_ControlData[2]); (* Specifies voltage *)
SET(TRUE, Var_Flag_Exe); (* Turns execution flag ON *)
END_IF;
IF(Var_Flag_Exe=TRUE)THEN (* Execution flag ON *)
G_OGLOAD(TRUE, H00, Var_ControlData, Var_Result); (* Performs readout *)
IF(Var_Result[0]=TRUE)THEN (* Execution finished *)
IF(Var_Result[1]=FALSE)THEN (* Normal completion *)
RST(TRUE, Var_Flag_Exe); (* Turns execution flag OFF *)
ELSE (* Error completion *)
(* Process on error completion *)
END_IF;
END_IF;
END_IF;
