`WOSA/XMC MCAPI and MCSPI Design Specification
`
`1.0 Overview
`
`1.0 Overview
`The WOSAlXMC Motion Control Software is comprised of several pieces of software. At the
`highest level of the software model reside the Motion Control Software Component and the Driver
`Administrator Application. Using the Driver Administrator, users may select and configure
`motion control drivers for specific motion control hardware. Next, software applications use the
`Motion Control Software Component to solve motion control problems. At a lower level, the
`component queries the Driver Administrator for the selected motion control driver, which it uses
`to manipulate the actual hardware.
`
`For example, a user may have an application used to optimize the initialization of their motion
`control hardware. In order to run the optimizing application, the user must first run the Driver
`Administrator, select the appropriate software driver from a list of hardware supporting the
`WOSAIXMC software model, and setup the software driver selected. Since the initialization
`tuning application uses the Motion Control Software Component, they are ready to tune their
`hardware's initialization process. What would happened if the user selected another
`implementation of motion control hardware? Again, the user would use the Driver Administrator
`to select the appropriate driver for the hardware and then run the same initialization tuning
`application.
`
`Since the Motion Control Software Component is independent of any hardware implementation,
`all application using it will instantly enjoy the larger target audience of all motion control
`hardware supporting the WOSAlXMC software model, instead of just one hardware
`implementation.
`
`This document describes all technical aspects of the WOSAIXMC MCAPI and MCSPI supporting
`software model. The first section of the document, discusses the general idea and some of the
`broad issues of the model, such as the design goals, tenn definitions, and target platfonns. After
`describing the model from a broad view, the next section, 2.0 Overall Design, describes the
`software model from a very technical perspective. In this section, a diagram displays all main
`objects in the model and how they interact with each other. The diagram encompasses the overall
`software design. Following the overall software design, the next section, 3.0 Scenario-Maps,
`tests the design, with several scenarios. Each scenario, such as initialization of the model,
`perfonning an absolute move, or perfonning a multi-axis interpolated move, is both graphically
`displayed and each step within it is described. Following the scenarios, four sections, 4.0 C/C++
`Support and 5.0 Visual Basic Support, describe how the application developer may program to the
`software model. The two fmal sections, 6.0 Driver Administrator MCAPI OLE Interfaces, 7.0
`Motion Component MCAPI OLE Interfaces, and B.O Motion Driver MCSPl OLE Interfaces, are
`references to both the MCAPI and MCSPI interfaces. Each OLE 2.0 Interface is discussed and
`the methods of each are listed. Appendix A of the document, contains a list of unresolved issues,
`currently being researched and a communication channel available for all reviewer feedback.
`
`1.1 Design Goals
`The following are the design goals to be met by the WOSAIXMC software model:
`
`1.
`2.
`3.
`4.
`
`5.
`6.
`
`Hardware independent software solution for motion control.
`Easily integrated into high-level languages such as Visual Basic and Excel's App Basic.
`Provide three modes of operation: 1.) Real Time, 2.) Code Generation, 3.) Mixture.
`Binary compatibility on the Windows NT 3.1, Windows NT 3.5, Chicago, and Windows
`3.1 platfonns.
`Full OLE 2.0 support and enabling.
`Easily extensible for new hardware.

`1.0 Overview
`
`7. Easily extensible for new hardware features.
`8. Optimal performance on all platforms supported.
`9. Easily extensible for remote motion control applications.
`10. Easily extensible for PLC motion control applications.
`11. Easily extensible for Serial motion control applications.
`
`Of the above goals, the top two are critical to create a path toward standardizing the WOSAIXMC
`solution for motion control applications. A hardware independent solution will open up the
`motion control software market, and giving high-level languages easy access to the model will
`help it proliferate in the large market.
`
`1.2 Definitions
`WOSA - Windows Open Service Architecture - this is the Microsoft open service model
`supported by Microsoft Windows to allow third party vendors a method of consistently extending
`Microsoft Windows.
`
`WOSAlXMC - WOSA extension for Motion Control - this is the extension for Microsoft
`Windows used to manipulate and control Motion Control hardware.
`
`MCAPI - Motion Control Application Programming Interface - this is the specific set of functions
`called by applications using Motion Control. The Motion Component provides the majority of the
`MCAPI functions, which are all hardware independent. Several functions in the MCAPI, used to
`access the current driver environment, are provided by the Motion Control Driver Administrator.
`
`MCSPI - Motion Control Service Provider Interface - this is the specific set of functions called by
`the Motion Component supporting the MCAPI. Each MCSPI software driver is hardware
`dependent for it directly communicates with a specific hardware implementation using the
`hardware implementations motion control language and communication registers or ports.
`
`Driver Administrator - The Driver Administrator is an independent Windows application used to
`install, configure, and remove Motion Device Drivers. The user may also toggle API diagnostic
`logging, for debugging, through the administrator. In addition to providing driver management
`services to the user, the administrator is used by all applications, using the WOSAlXMC software,
`to access the current Motion Device Driver. When queried by the component, the administrator
`returns a pointer to the current driver's IUnknown interface. The administrator functions make
`up a small subset ofthe MCAPI mentioned above.
`
`Motion Control Component - All applications using the WOSAIXMC software model
`communicate directly with the Motion Control Component. The component is a hardware
`independent implementation of the motion control abstraction specified by the MCAPI. Both the
`functions supported by the component and those supported by the Driver Administrator together
`make up the MCAPI.
`
`Motion Control Driver - The Motion Control Driver is the actual hardware dependent software
`driver that uses the motion control command language to communicate with the motion control
`hardware that supports it. Every driver supports a set of functions called core functions. These
`are primitive functions required by all motion applications. The core functions are a subset of the
`MCSPI. The remaining set of MCSPI functions are called extended functions and are not required
`to be implemented.
`
`Motion Control Driver Stub - The Motion Control Driver Stub is a secondary Motion Driver
`supplied to support all MCSPI extended functions not supported by the Motion Driver. A

`
`1.3 Target Platforms
`Currently there are five main target platforms, two of which exist today. Windows 3.1, Windows
`NT 3.1 are target platforms currently out in the market. Chicago, a future release of windows will
`be a critical target platform for it will change the software model provided by supporting a deep
`integration of OLE 2.0. Finally, Daytona and Cairo, future versions of Windows NT 3.1 will be
`targeted. Daytona will be a small upgrade where Cairo, will bring NT up to date with the changes
`implemented in Chicago. See figure 4 for a description of the planned target order for each
`software entity in the WOSAlXMC model.

`NOTE: Currently the PC Bus is the assumed motion control hardware target. Since the WOSAlXMC model
`supports Windows NT, other hardware busses can be easily integrated into the overall model.
`
`1.4 Major Change List
`While reading this specification, you will notice several major changes to the overall design of the
`Motion Control Component. This section lists and describes each change that has occurred.
`
`•
`
`Separated Design From Analysis - This document contains all design issues describing the
`Motion Software Component. All analysis issues have been extracted to the Motion Control
`Component, Analysis Specification.
`• Removed Thunking Layer - All 32-bit to 16-bit thunking and all 16-bit to 32-bit thunking
`has been removed from the design. Instead of using thunking to provide support for 16-bit
`Windows 3.1, one set of source code will be built twice: once to create a 32-bit version of the
`software and once to create a 16-bit version. By creating two builds from one source, our
`development time will be reduced, for no development time will be devoted to creating
`complex thunks. In addition, the 16-bit software will be much faster for most of the actual
`computation is done by each Motion Driver, which must be compiled as 16-bit for 16-bit
`applications.
`• Reorganized All MCAPI OLE Interfaces - All MCAPI OLE Interfaces have been
`reorganized to follow a more object oriented style. Most interfaces describe a particular
`portion of the overall motion abstraction. For example, the IJoystick interface describes all
`functions used to manipulate a joystick.
`• Reorganized All MCSPI OLE Interfaces - Similar to the MCAPI OLE Interfaces, all
`MCSPI OLE Interfaces have been reorganized to follow a more object oriented style.

`1.0 Overview
`
`Currently, the MCSPI OLE Interfaces are a close mapping of the MCAPI OLE Interfaces.
`Implementation of all MCSPI OLE Interfaces is not required.
`• Revised all Interaction and Scenario Maps - All interaction and scenario maps have been
`revised to take into account the removal of the thunking layer, and the reorganization of both
`the MCAPI and MCSPI interfaces.
`• Added Several Scenario Maps - The following new scenario-maps have been added to the
`specification:
`1.
`Initialization Tuning (Code Generation MCSPI)
`2. Multi-Axis Linear Interpolated Move (Extended MCSPI)
`• New C/C++ Support Section - A new section briefly describes how to program the Motion
`Control Component using both the C and the C++ programming languages.
`• Revised Visual Basic Support Section - The section describing Visual Basic support has
`been revised to include more information about OLE Automation and a new section,
`describing OLE Custom Controls, has been added.
`• New Unresolved Issues Section - A new appendix section, describing unresolved issues, has
`been appended to the back of the document. This section discusses any issues that need more
`research.

`2.0 Overall Design
`
`2.0 Overall Design
`The overall design, discussed in this section, includes all main objects found within the software
`model and how they interact with each other. When an object communicates, in any way, with
`another object, the two objects are interacting. The composite of all interactions taking place
`within the software model make up what is called the main interaction-map, which is discussed in
`the following section.
`
