Bus Communication Overview
Communication between the controller and the Product takes place with
commands established by IEEE-488 standards and commands specifically
related to the Product. The commands in Table 6-6 are all the remote
commands, both common and device-dependent.
Definitions of the different types of messages used on the IEEE-488 bus:
•
Device-dependent commands are messages that transfer information directly
between the Product and the IEEE-488 controller. Some commands cause
an action to take place in the Product. Others, called queries in the IEEE
standards, ask for information, and always generate a response message
from the Product. While message format is governed by IEEE-488 standards,
messages themselves can be unique to the Product. For example, use
device-dependent commands to set the input binding post or calibration type.
•
Common commands defined by IEEE standards are used for functions
common to most bus devices. Examples include the command to reset a
device (*RST) and the query for device identification (*IDN?). Common
commands and queries can be identified easily because they all begin with
an asterisk (*).
