Functions

丰富的指令集:
运算种类众多，便于编程：
- 基本操作,如二进制逻辑运算、结果赋值、存储、计数、产生时间、装载、传输、比较、移位、循环移位、产生补码、调用子程序（带局部变量）
- 集成通信命令（例如，USS 协议、Modbus RTU、S7 通信“T-Send/T-Receive”（T 发送/T 接收）或自由端口模式 (Freeport)）
- 使用简便的功能，如脉冲宽度调制、脉冲序列功能、运算功能、浮点运算功能、PID 闭环控制、跳转功能、环路功能和代码转换
- 数学函数，例如 SIN、COS、TAN、LN、EXP
计数:
用户友好的计数功能配以集成的计数器和高速计数器指令给用户开辟了新的应用领域。
中断处理：
- 边沿触发中断（由过程信号的上升沿或下降沿触发）允许对过程中断作出极快的响应。
- 时间触发中断。
- 当达到设定值或计数器方向改变时，可触发计数器中断。
- 通信中断使得能迅速方便地与周围的设备如打印机或条码阅读器交换信息。
口令保护
测试和诊断功能：
易于使用的功能支持测试和诊断，例如，在线/离线诊断。
在测试和诊断过程中“强制”输入和输出：
可不在循环周期内独立设置输入和输出，例如可以检测用户程序。
按照 PLCopen 对简单运动进行的运动控制。
