FP_MEWNET_W_GET_ERROR_OCCURRENCY

按错误类型获取MEWNET-W单元上出现的错误数

此FP指令读取由s_Slot指定的插槽编号中MEWNET-W单元上出现的错误数。

输入

s_Slot (ANY16): 扩展单元的插槽编号

输出

d_dutMewnetWErrorOccurrency: 按错误类型将出现的错误数存储在FP_MEWNET_W_ERROR_OCCURRENCY_DUT中。

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。

	VAR
		bEnable: BOOL:=FALSE;
		iSlot: INT:=0;
		dutMewnetWErrorOccurrency: FP_MEWNET_W_ERROR_OCCURRENCY_DUT;
	END_VAR

LD本体

当变量bEnable设置为TRUE时，执行此函数。
