TCP/IP Interface Object

Overview

The TCP/IP interface object presents the instances (per network), attributes and services described below.

Class ID

F5 (hex), 245 (decimal)

Instance IDs

The TCP/IP interface object presents 2 instance values:

Attributes

TCP/IP interface object attributes are associated with each instance, as follows:

Instance ID = 0 (class attributes):

Attribute ID	Description	GET	SET
01	Revision	X	—
02	Max Instance	X	—
X = supported — = not supported

Instance ID = 1 (instance attributes):

Attribute ID	Description	Type	GET	SET	Value
01	Status	DWORD	X	—	0x01
02	Configuration Capability	DWORD	X	—	0x01 = from BootP 0x11 = from flash 0x00 = other
03	Configuration Control	DWORD	X	X	0x01 = out-of-box default
04	Physical Link Object	STRUCT	X	—
	Path Size	UINT
	Path	Padded EPATH
05	Interface Configuration	STRUCT	X	X	0x00 = out-of-box default
	IP Address	UDINT
	Network Mask	UDINT
	Gateway Address	UDINT
	Name Server	UDINT
	Name Server 2	UDINT
	Domain Name	STRING
06	Host Name	STRING	X	—
X = supported — = not supported

Services

The TCP/IP interface object performs the following services upon the listed object types:

Service ID		Description	Class	Instance	Notes
hex	dec	Description	Class	Instance	Notes
01	01	Get_Attributes_All	X	X	Returns the value of all attributes.
0E	14	Get_Attribute_Single	X	X	Returns the value of the specified attribute.
10	16	Set_Attribute_Single1	—	X	Sets the value of the specified attribute.
X = supported — = not supported
1. The Set_Attribute_Single service can execute only when these preconditions are satisfied: Configure the Ethernet communication module to obtain its IP address from flash memory. Confirm that the PLC is in stop mode.
