HscInfo_GetCurrentSpeed

返回高速计数器通道的当前速度

此指令返回iChannel指定的高速计数器通道的当前速度（Hz）。

参数

输入

iChannel (INT)

高速计数器通道：

FPS: 0, 2

FP-X R: 0, 1

FP-X 16K C14T: 0, 1, 2

FP-X 32K C30T, C60T: 0, 1, 2, 3

FP0R: 0, 1, 2, 3

FP0: 0, 1

FP-e: 0, 1

输入/输出

dutMemory (DUT): HscInfo_GetCurrentSpeed_DUT

输出

VAR_OUT (DINT): 存储iChannel所指定通道的当前速度

示例

POU头

所有用于编程此函数的输入和输出变量已在POU头中声明。所有编程语言使用相同的POU头。
