APT Modular Rack Controller
Consider the ActiveX Control supplied for the APT stepper controller module.
This Control provides a complete user graphical instrument panel to allow the motor
unit to be manually operated, as well as a complete set of software functions (often
called methods) to allow all parameters to be set and motor operations to be
automated by a client application. The instrument panel reflects the current operating
state of the controller unit to which it is associated (e.g. such as motor position).
Updates to the panel take place automatically when a user (client) application is
making software calls into the same Control. For example, if a client application
instructs the associated stepper motor Control to move a motor, the progress of that
move is reflected automatically by changing position readouts on the graphical
interface, without the need for further programming intervention.
The APT ActiveX Controls collection provides a rich set of graphical user panels and
programmable interfaces allowing users and client application developers to interact
seamlessly with the APT hardware. Each of the APT controller modules has an
associated ActiveX Control and these are described fully in system online help or the
handbooks associated with the controllers. In addition to the main ActiveX Server, a
number of other utilities are supplied with the APT system, most notably APTUser and
APTConfig. Note that these utilities themselves take advantage of and are built on top
of the powerful functionality provided by the APT ActiveX Server (as illustrated in the
system architecture diagram below).
