– Valid logical addresses are 1 through 255. Most Agilent
modules are statically configured modules, which means that
you have to physically set the address on the switch. To
dynamically configure a module which supports dynamic
configuration, its logical address must be set to 255. A
dynamically configured module’s address is set
programmatically by the resource manager. Note, however, if a
statically configured module is set to 255, the resource manager
will not dynamically configure any module.

– Each instrument must have one plug-in module assigned as an
Instrument Identifier. The Instrument Identifier is the module
with its logical address set to a multiple of 8, such as 8, 16, or 24.
– An instrument consisting of multiple modules is called a virtual
instrument. The modules of the virtual instrument must be
assigned successive logical addresses beginning with the address
of the Instrument Identifier. For example, to create a scanning
multimeter virtual instrument which consists of a multimeter and
two multiplexers, the logical addresses could be set to:
24 (multimeter)
25 (1st multiplexer)
26 (2nd multiplexer)
Note, however, you cannot combine multiple modules of the
same type (like multiple multimeters or multiple counters) into
virtual instruments.
– A plug-in module with a logical address that is not a multiple of
8, or that is not part of a virtual instrument, is an unassigned
module. Such modules must be programmed at the register level,
rather than with SCPI commands. (A secondary GPIB address
can be given to an unassigned module with the Command
Module’s User-Defined Commander/Servant Hierarchy table
(see the Agilent E1406 User’s Manual).)
