一些的使用技巧包括程序的组织和功能的实现两部分，程序组织方面，要试着理解FFDB这些块的功能，了解系统OB的含义和用法，尝试着把程序按照块来组织，通过调用减少重复工作，提高复用性，使程序更清晰可读，这是提高编程水平，组织大型程序的基础。功能实现方面，学习和了解一些常用的编程模式很有必要，比如顺序转换的编程结构，PID调节、步进电机控制等一些功能的原理、实现方法以及系统内置的工艺模块的用法，有可能的话尝试自己不用系统块写一个PID调节或者运动控制的功能，这些都是从熟手到高手的分水岭。

BCD码的低3位各位只能是0~9，如果是16#A~16#F则会出错。计数器的预设值PV是0~999的BCD码，可以用格式为C#的常数（C#1~C#999）作为计数器的预设值。下图用MW42提供计数器的预设值PV，如果用MOVE指令将十进制数348（对应的十六进制数为16#15C）传送给MW42，进入RUN模式时，操作系统将它转换为BCD码时出错（16#15C不是BCD码），不能切换到RUN模式。输入预设值348时，应改为将C#348传送给MW42，它会自动地变为W#16#348，当然也可以直接输入16#348。
