FP_IPV4_GET_MAC

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
		bSetIpv4Address: BOOL:=FALSE;
		bGetConnection: BOOL:=FALSE;
		bGetMac: BOOL:=FALSE;
		dutIPv4Connection: FP_IPv4_CONNECTION_DUT;
		dutIPv4MAC: FP_IPv4_MAC_DUT;
	END_VAR

POU本体

此示例设置由s_Address指定的以太网连接参数。 请确保也在[系统寄存器(Y)] > [以太网] > [用户连接]下的项目导航中设置合适的参数。 当bGetConnection设置为TRUE时，连接参数将输入到DUT FP_IPv4_CONNECTION_DUT。 当bGetMac设置为TRUE时，MAC地址的参数将输入到DUT FP_IPv4_MAC_DUT。
