西门子S7-1200PLC高速计数器实例及应用详解ABC去学电气技术西门子S7-1200 CPU 提供了最多 6 个(1214C )高速计数器,其独立于 CPU 的扫描周期进行计数。
可测量的单相脉冲频率最高为100KHz ,双相或A/B 相最高为30KHz ,除用来计数外还可用来进行频率测量,高速计数器可用于连接增量型旋转编码器,用户通过对硬件组态和调用相关指令块来使用此功能。
01高速计数器工作模式高速计数器定义为 5 种工作模式1、计数器,外部方向控制。
2、单相计数器,内部方向控制。
3、双相增 /减计数器,双脉冲输入。
4、5A/B 相正交脉冲输入。
5、监控 PTO 输出。
每种高速计数器有两种工作状态。
1、外部复位,无启动输入。
2、内部复位,无启动输入。
所有的计数器无需启动条件设置,在硬件向导中设置完成后下载到 CPU 中即可启动高速计数器,在 A/B 相正交模式下可选择 1X(1 倍) 和 4X(4 倍)模式,高速计数功能所能支持的输入电压为 24V DC, 目前不支持 5V DC 的脉冲输入,表 8-1 列出了高速计数器的硬件输入定义和工作模式。
并非所有的 CPU 都可以使用 6 个高速计数器,如 1211C 只有 6 个集成输入点,所以最多只能支持4 个(使用信号板的情况下)高速计数器。
由于不同计数器在不同的模式下,同一个物理点会有不同的定义,在使用多个计数器时需要注意不是所有计数器可以同时定义为任意工作模式。
高速计数器的输入使用与普通数字量输入相同的地址,当某个输入点已定义为高速计数器的输入点时,就不能再应用于其它功能,但在某个模式下,没有用到的输入点还可以用于其它功能的输入监控PTO 的模式只有 HSC1 和 HSC2 支持,使用此模式时,不需要外部接线,CPU 在内部已做了硬件连接,可直接检测通过PTO 功能所发脉冲。
02高速计数器寻址CPU 将每个高速计数器的测量值,存储在输入过程映像区内,数据类型为 32 位双整型有符号数,用户可以在设备组态中修改这些存储地址,在程序中可直接访问这些地址,但由于过程映像区受扫描周期影响,在一个扫描周期内,此数值不会发生变化,但高速计数器中的实际值有可能会在一个周期内变化,用户可通过读取外设地址的方式,读取到当前时刻的实际值。
