User Scenario: Viewing Property Help

The purpose of using a Help element in an IMDF file is to create help text for device-

specific properties. A user of your adaptor can display the help text at the command line

using the imaqhelp command.

The following example shows how a user displays the help text for a device-specific

property using the imaqhelp command. To see how to create this help in an IMDF file,

see “Creating AdaptorHelp Nodes” on page 7-8.
