Data type Description
1 Interface Speed Get UDINT Used interface speed in MBits/s (10, 100,
1000, …). 0 is used when the speed has not
been determined or is invalid because of
detected problems.
2 Interface Flags Get DWORD Interface Status Flags:
Bit 0: Link State (1: Link up),
Bit 1: 0: Half-Duplex, 1: FullDuplex1,
Bits 2 through 4: Autoneg Status (0: Autoneg
in Progress, 1: Autoneg unsuccessful,
2: unsuccessful but Speed detected,
3: Autoneg success, 4: No Autoneg),
Bit 5: manual configuration requires reset
(always 0 because not needed),
Bit 6: detected hardware error.
3Physical
Address
Get ARRAY of 6
USINTs
MAC address of physical interface.

6 Interface
Control
Get/Set Struct Control
Bits WORD
Forced Iface
Speed UINT
Control Bits:
Bit 0: Autoneg enable/disable (1: enable),
Bit 1: Duplex mode (1: full duplex, if Autoneg
is disabled).
Interface speed in MBits/s: 10, 100,…, if
Autoneg is disabled.
7 Interface Type Get USINT Value 0: Unknown interface type,
Value 1: The interface is internal,
Value 2: Twisted-pair,
Value 3: Optical fiber.
