FP_IPV4_GET_MAC

POU header

All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.

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

POU body

This example sets the Ethernet connection parameters specified by s_Address. Please ensure the suitable parameters are also set in the project navigator under [System registers] > [Ethernet] > [User connections]. When bGetConnection is set to TRUE, the connection parameters are entered into the DUT FP_IPv4_CONNECTION_DUT. When bGetMac is set to TRUE, the parameters of the MAC address are entered into the DUT FP_IPv4_MAC_DUT.
