8.7.3.3 Attribute 3, Configuration Control
The Configuration Control attribute is a bitmap used to control network configuration
options and determines how the device shall obtain its initial configuration at start up,
see also “Obtaining the IP parameter” on page 156.
Bit Function
Description
0-3
Startup
Configuration
0:
-
In switch position 0x00 the measuring system
obtains the IP parameters from the FLASH.
-
In switch position 0x01 up to 0xFE the measuring
system obtains the IP parameters from the actual
switch position.
-
In switch position 0xFF the measuring system
obtains the IP parameters from DHCP.

not supported
2:
In switch position 0xFF the measuring system
obtains the IP parameters from DHCP upon start-up.

8.7.3.4 Attribute 4, Physical Link Object
This attribute identifies the object associated with the underlying physical
communications interface. There are two components to the attribute:
● Path Size in UINTs
● Path
The Path contains a Logical Segment, type Class, and a Logical Segment, type
Instance that identifies the physical link object. The physical link object itself typically
maintains link-specific counters as well as any link specific configuration attributes.
Because the CIP port associated with the
TCP/IP Interface Object
has an
Ethernet physical layer, this attribute points to an instance of the
Ethernet Link
Object
, class code = 0xF6.
