The following sample program, written in structured text, demonstrates
how to configure the module in CCW.

(* Ch1 Config LSB *)
ConfigArray[4] := 0;
(* Ch1 Config MSB *)
ConfigArray[5] := 0;
(* Ch2 Config LSB *)
ConfigArray[6] := 0;
(* Ch2 Config MSB *)
ConfigArray[7] := 0;
(* Ch3 Config LSB *)
ConfigArray[8] := 0;
(* Ch3 Config MSB *)
WriteConfig(true,u800Slot,32,8,ConfigArray);
(* Write the config. data to the module*)
ReadModStatus(true,u800Slot,16,1,IF4U_S1_ModStatus);
(* Read general module status *)
ReadOCStatus(true,u800Slot,80,1,IF4U_S1_OCStatus);
(* Read open-circuit status *)

(* Read the input data from the module. *)
x := 9;
CHData := 0;
(* Preset the for loop exit value and channel data. *)
for i := 1 to x by 2 do
(* For Loop. *)
