The TCP/IP Object (class code 0xF5) is part of the auxiliary/communications
processor EIP protocol stack. It holds the configuration relating to a device
TCP/IP network interface.

Description of
Attribute
Bits 0 -3 (value)
• 0: Not configured
• 1: Configuration based on BOOTP, DHCP, or NV stored
configuration
• 2: IP address based on the address switches (module
base)
Bits 4 and 5 relate to pending configuration changes in
configuration attributes (see standard for details)
Bit 6 - ACD Status is set when an address conflict is
detected
Bit 7 - ACD Fault is set when the current interface
configuration cannot be used due to an ACD
Bit 0 set: BOOTP client capable
BIT 2 set: DHCP client capable
Bit 4 set: Interface Configuration attribute is settable
Bit 5 set: Hardware configurable (address switches)
Bit 6 Not set: A change in the Interface Configuration
attribute takes place immediately
Bit 7 set: The module is ACD capable
Configuration method, Bits 0 - 3 (value)
0: Static
1: BOOTP
2: DHCP
Note: Writing 0 to the Configuration Control makes
BOOTP/DHCP addresses non-volatile.
When the TCP/IP addressing is based on the hardware
switches, the default gateway address setting is
192.168.1.1 unless the switch defined module address is
itself 192.168.1.1, in which case the default gateway
address reverts to the legacy setting of 0.0.0.0. The
default gateway address forms part of Attribute 5,
Interface configuration.
