FP_IPV6_GET_CONNECTION

Get connection parameters

This FP instruction reads the parameters from the Ethernet connection and writes the values into the DUT FP_IPV6_CONNECTION_DUT.

Parameters

Input

nPort (WORD, INT, UINT)

Ethernet port on CPU (FP7 E types):

SYS_ETHERNET_USER_CONNECTION_1–SYS_ETHERNET_USER_CONNECTION_216

Output

dutIPv6Connection (FP_IPV6_CONNECTION_DUT): Parameters of the Ethernet connection

Example

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
		bGetConnection: BOOL:=FALSE;
		dutIPv6Connection: FP_IPv6_CONNECTION_DUT;
		bGetMac: BOOL:=FALSE;
		dutIPv6MAC: FP_IPv6_MAC_DUT;
	END_VAR

POU body

When the variables bGetConnection and bGetMac are set to TRUE, the functions are carried out.
