GPIB MATLAB Structure Reference
You do not use all message fields in all messages. For example, a message to
send data would not use the message field
.RecData, but would use the field
.SendData. However, knowing the possible message fields will be helpful when
you are creating any of the message structures.
This section includes the following topics:
•
GPIB Initialization and Termination Message Structures — Description
of the message fields for the initialization and termination structures
associated with the GPIB Setup block.
•
GPIB Send/Receive Message Structure — Description of the message
fields for the send/receive structure associated the GPIB Send/Receive block.
•
Shortcuts and Features for Messages — Shortcuts to using the GPIB wrt
and
rd commands.
•
Supported Data Types for Message Fields — List of supported data types
and the format you use to indicate those types in message fields.
