T_HNLINK
A variable of this type represents a network connection handle. The structural elements should not be written to or modified directly. Variables of this type are used for internal data exchange.
One instance is required for each network connection (TwinCAT system<->Ethernet LAN adapter<->external controller). The same instance is then transferred to other communication blocks as VAR_IN_OUT parameter.
