方法一
定义每个轴的基本功能，包括上电、下电、走相对、走绝对、读位置、读状态、复位、停止等。

运行时，先输入iAxisNum，再执行命令即可。
方法二
定义轴基本功能，同上。区别在于Main主函数：
在Main中添加Action
ACT_PowerOn方法代码，其余类似。
1 FOR i:=1 TO 13 DO
2 Axis[i].M_PowerOn(bExcute:=cmdPowerOn[i],bStatus=>PoweronStatus.bStatus,bBusy=>PoweronStatus.bBusy,bActive=>PoweronStatus.bActive,bError=>PoweronStatus.bErr,dErrorID=>PoweronStatus.dErrID);
3 END_FOR
Main函数代码：
1 //定义接口及继承关系
2 Axis : ARRAY[1..10] OF Axis_Base_PTP;
3 Axis11 : Axis11_PTP;
4 Axis12 : Axis12_PTP;
5 Axis13 : Axis13_PTP;
6
7 cmdPowerOn AT%I* : ARRAY[1..13] OF BOOL;
8 cmdPowerOff AT%I* : ARRAY[1..13] OF BOOL;
9 cmdMoveRela AT%I* : ARRAY[1..13] OF BOOL;
10 cmdMoveAbs AT%I* : ARRAY[1..13] OF BOOL;
11 cmdReset AT%I* : ARRAY[1..13] OF BOOL;
12 cmdStop AT%I* : ARRAY[1..13] OF BOOL;
13 cmdReadPos AT%I* : ARRAY[1..13] OF BOOL;
14 cmdReadStatus AT%I* : ARRAY[1..13] OF BOOL;
15 cmdHome AT%I* : BOOL;
16 cmdGlassForward AT%I* : BOOL;
17 cmdGlassBack AT%I* : BOOL;
18 cmdTurnIn AT%I* : BOOL;
19 cmdTurnOut AT%I* : BOOL;
主函数调用Action方法进行轮询：
1 ACT_PowerOn();
2 ACT_PowerOff();
3 ACT_MoveAbs();
4 ACT_MoveRela();
5 ACT_Reset();
6 ACT_Stop();
7 ACT_ReadPos();
8 ACT_ReadStatus();
运行时，需针对每个轴的每个指令进行下发。
方法三
利用面向对象中的接口和继承方法。借鉴示例。
首先定义接口及属性方法，定义一个基类实现接口中的属性和方法，若需要再定义类继承基类。
Main函数；
1 PROGRAM MAIN
2 VAR
3 fbGenerator1 : FB_Generator;
4 fbGenerator2 : FB_GeneratorEX;
5 iGenerator : I_Generator;
6 tCycletime: TIME :=T#3S;
7 sVendor: STRING;
8 change: BOOL :=TRUE;
9 output: BOOL;
10 END_VAR
1 IF change THEN
2 iGenerator:=fbGenerator1;
3 ELSE
4 iGenerator:=fbGenerator2;
5 END_IF
6
7 output:=iGenerator.Flash();
8 iGenerator.Cycletime:=tcycletime;
9 sVendor:=iGenerator.Vendor;
运行时，通过接口切换调用不同轴模块。
优缺点比较
方法一：上位机调用变量较少，主程序复杂；
方法二：上位机调用变量较多，主程序简单；
方法三：上位机调用变量较少，主程序轴联动复杂；
