About Hardware Interface Files
Understanding Hardware Interface Files
The resources in your Station Builder application resource lists are defined by the
hardware interface file (or .hwi file) installed with your system software.
Resource examples include conditioners, valve drivers, digital inputs, and so
forth. The .hwi file defines what internal components are available to your
controller, which controller slots they are installed in, and which rear-panel
connectors they are accessed through.
Hardware interface file
syntax
Hardware interface files (.hwi) are text files. The text description of a resource in
an .hwi file includes proximity information, such as the location of the slot in the
chassis in which the resource is installed, and the rear-panel connectors through
which it can be accessed. The text in hardware interface files uses precise syntax
which must be followed when editing the text directly.
.hwi file and the
Station Builder
application
You use the Station Builder application (one of the applications included with
MTS 793.00 System Software) to define test stations by allocating some or all of
the resources listed in the .hwi file.
Initial .hwi file
The .hwi file associated with a given controller is typically created at MTS
according to the resources included with the controller. It may be necessary to
edit this file if system resources are added, removed, or repositioned in the
controller chassis.
