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.
