Data Maataget.
3-62.
The major
portion
of communications
transmit-
ted
over
the
Bus
is
accomplished by
data messages.
Data
messages
are used
by
the controller to
program
the
Model 34SSA and
are
used
by
the
34SSA
to transmit
measurement
data.
These
functions are explained
in
the
following paragraphs.
3-83.
Programming.
The 345SA
is
programmed
by means
of data messages
sent
over
the
Bus from
the
controller.
These
messages
are
composed
of
two
parts
—
the ad-
dress
command
and
the
program
information.
The
ad-
dress
command
contains the
"talk"
and
"listen" ad-
dresses
of
the devices involved;
in this
case,
the
talk
ad-
dress
of
the controller
and
the
listen
address
of
the
34S5A.
The program
information contains
the
codes of
the
345SA
controls
to
be
programmed.
Syntax of
the ad-
dress
command
portion
of
the
data
message
is
depen-
dent
upon
the controller
being
used.
For
the
proper
syn-
tax refer to the controller
manual. Syntax
for the pro-
gram
information portion
consists
of
the
program
codes
listed in
Table
3-4.
