11 Obtain IP parameters via Flash or DHCP
The TCP/IP Interface Object is used to configure the TCP/IP network interface; it contains,
among other things, device IP address, network mask, and gateway address. The settings are made
via the Object 0xF5, Instance 1, and the Attributes 3 Configuration Control and 5
Interface Configuration. The attributes are generally controlled via a DHCP server program,
see 80.

11.1.1 Attribute 3, Configuration Control
The Configuration Control attribute is bit-coded and defines how the IP parameters are
assigned to the measuring system during the start-up phase, see also “Obtaining IP Parameters” on
Page78.
Bit Function Description
0-3
Startup
Configuration
Value = 0: A FLASH provides the IP parameters to the measuring system.
Value = 2: A DHCP provides the IP parameters to the measuring system.
Attribute 3 is not evaluated if the switch positions are different; hardware
switch specifications apply.
0 (FALSE): is not supported
