9.2.1.4.1. Instance attributes
Instance attribute “Status”
This attribute presents the status of the TCP/IP network interface.
Table 95. Status bit descriptions
Bit(s) Called Definition
0-3 Interface configuration status
Indicates the status
of the interface
configuration attribute
Value Definition
0
The Interface Configuration
Attribute has not been configured
1
The Interface Configuration
Attribute contains valid configuration obtained from BOOTP, DHCP or non-
volatile storage.
2
The IP address member of the Interface Configuration Attribute contains valid
configuration, obtained from hardware settings
3-15 Reserved for future use
4 Mcast pending Indicates a pending configuration change in the TTL Value and/ or Mcast Config attributes.
5 Interface configuration pending Indicates a pending configuration change in the Interface Configuration attribute.
6 Acdstatus Set(1) Address Conflict Detected, Clear(0) No Address Conflict Detected
7-31 Reserved Always zero
Instance attribute “Configuration Capability”
This attribute presents the capability flags (that is, the
support for the optional network configuration capability) of
the TCP/IP network interface.
Table 96. Configuration capability bit descriptions
Bit(s) Called Definition
0 BOOTP Client Supports BOOTP (FALSE)
1 DNS Client
Supports capable of resolving DNS
names (FALSE)
2 DHCP Client Supports DHCP (TRUE)
3 DHCP-DNS Update Always zero
4 Configuration Settable TRUE, if configuration settable
5 Hardware Configurable
Configuration can be obtained from
hardware settings (FALSE)
6
Interface Configuration Change
Requires Reset
Configuration change results in
reset (FALSE)
7 AcdCapable Supports ACD (TRUE)
8-31 Reserved Reserved, always zero
Instance attribute “Configuration Control”
This attribute allows control of the TCP/IP network
interface configuration.
When using the Configuration Control attribute, the device
can be configured to use statically assigned IP values or
DHCP. If the value is changed from DHCP to statically
assigned, the device will continue using the current IP
address. When changing from statically assigned to DHCP,
the drive will try to get an IP address from the DHCP
server. If this fails, the communication with the drive
cannot be re-opened and you must set the IP address
manually from the panel or enable the DHCP server in
the network.
Changing the Configuration Control is not allowed if the I/O
connection is open.
Table 97. Configuration control bit descriptions
Bit(s) Called Definition
Value Definition
0-3 Configuration Method
Determines how the device obtains its IP
related configuration
0 The device uses statically-assigned IP configuration values.
1 The device obtains its interface configuration values via BOOTP
2 The device obtains its interface configuration values via DHCP
3-15 Reserved for future use.
4 DNS Enable If TRUE, the device resolves host names by querying a DNS server
5-31 Reserved Reserved, always zero
