BX Controller Overview
Berkeley's
Fifth Generation Controller Family
 The BX controller
is an integrated motion-and-machine controller with internally powered
servo drives. It features an expandable 100 Mbit Ethernet I/O system,
scalable serial ports, and an object based development environment.
The controller provides full system-centric machine control including
control of servomotors, actuators, multi-axis robots, slides and
process elements. By unifying the control of an entire machine or
module, the controller maximizes throughput and reliability while
dramatically reducing total system cost and integration effort.
The controller is available in configurations of up to 8 axis of
control and 6 internally powered brushed or brushless servo drives.
The
BX controller is your one stop solution to machine control, providing
enterprise and operator interface, scheduling, I/O, motion and process
control in one tightly integrated, yet flexible development/runtime
environment. In short, the BX controller provides complete hardware/software
machine control in a single, flexible, reliable, and easy to use architecture.
No longer is it necessary to integrate disparate control technologies
to automate your machine or process.

Hardware Features
Internal
Drives
As many as eight axes of control per controller, with up to six internally
powered servo drives drastically reduces the integration effort required.
Drives support DC brushed Servo, AC Brushless Servo and AC Linear
Motors. Drives are capable of up to 1200 W output per axis.
E-stop Circuitry
Internal force guided contactors disconnect drive power from the internally
powered drives, reducing wiring, saving panel space and increasing
safety and reliability. E-Stop circuitry can be daisy chained to provide
system wide E-Stop functionality when employing multiple controllers.
Light
Curtain Circuitry
Light curtain circuitry is pre-integrated for convenient connection
of light curtains or other safety devices. Pre-integration ensures
that safety circuit interrupts are automatically handled by the BX
controller error handler.
Single Cable Connections
The BX controller directly connects to servomotors with single pre-tested
cables that are connectorized at both ends. This eliminates the need
to use separate power and feedback cables for motor connection.
High Speed Internal I/O
The optically isolated 46 I/O points are fully integrated and configurable.
All machine states including I/O are known in real time to the BX
controller.
Ethernet
Primary communication to the BX controller is via a 100MB Ethernet
port in this truly Ethernet controller. All machine states and variables
are shared with other controllers and Windows NT by simply connecting
through this low cost and high-speed bus. Serial connection is also
available.
64-bit RISC Processor
A single high performance 64-bit RISC processor manages all sequencing,
motion and I/O logic control. All variables and calculations are done
with double precision floating-point math.
Expandable and Configurable
The BX controller is a fully modular system that allows for optional
expansion of serial ports, analog and digital I/O and operator interfaces.
The controllers themselves are configurable to allow for a varying
number of axes and drive configurations. In addition, auxiliary components
such as Ethernet distributed I/O allow for further expansion of the
system.
Flexible Mounting Scheme and Small Footprint
The BX controller is designed with space constraints in mind. The
controller is exceptionally small given the integration of servo amplifiers
and safety circuitry. In additional to this, the controller allows
for traditional back-mounting, while also allowing for flat-mounting,
providing the user with further flexibility in mounting the controls.
Software Features
64
bit Processing
The BX controller utilizes 64-bit processing with floating point computation.
Integrated Software
On-line development and runtime software environment is included.
Optional off-line development tools and project tools are also available.
Layered Software
Berkeley's software environment is layered to provide the right level
of software for all types of users—from the Quickstart machine
database which provides convenient system configuration tools, to
the lowest levels of code for those who want the utmost in flexibility.
Integrated Error Handling
The BX controller incorporates a host of firmware resident error
handling to provide increased safety and state information, without
requiring extensive programming. The controller comes with integrated
error handling for such things as E-Stop interrupts, axis limit
interrupts, axis over-torque, etc.
Scheduling and State Machines
All the scheduling and state machines needed to handle complex machine
or production coordination is enabled through the BX controller
software environment. Unlike other controllers, a host PC is not
required to perform scheduling and state transition information.
All the tools necessary are included in the software environment,
allowing users to simplify the interactions between disparate control
technologies.
Programmable Application Layer
The Berkeley software has been developed to allow user defined commands.
This feature enables users to customize the functionality of the
software without requiring factory changes to firmware.
Protocol Emulation
Where integration into existing or legacy systems may be required,
the BX controller software environment allows for the emulation
of host protocols. This allows for drop-in-replacement of legacy
equipment without the need for code-rewrite. Simply pull out your
existing controller and drop in the BX controller. The BX controller
will then interpret the host protocol to allow for programming free
changeover.
Electronic Line Shafting (ELS)
ELS electronically links the motion of one axis (slave) to another
axis (master), providing a flexible and programmable relationship
between the slave and master axes.
Cam Profiling (CP)
Tightly coordinated non-linear motion profiles can be commanded
by user defined position-based tables to specify a relationship
between any master axis and its slave axis.
Programmable Limit Switch (PLS)
In applications where processes are synchronized by a lineshaft,
PLS can electronically actuate control functions at specific points
in the machine cycle, and in full coordination with the rest of
the machine operation.
Flying Position Measurement (FPM)
High-speed capture of position is enabled to satisfy the most demanding
of registration, flying shear and similar applications.
Autotuning
Integrated autotuning features are included to provide simplified
servo tuning and reduced commissioning and maintenance efforts.
Integrated General Loop Controllers (GLC)
The BX controller software environment includes integrated servo
loops (PID's) for position velocity and torque control. In addition,
the environment includes general purpose controllers (GLC's), analog
and digital I/O logic to handle the most demanding process control
applications. All servo, GLC, and i/o logic are tightly coordinated
via a common state information database to provide integrated development
and runtime environments.
Predictive Maintenance
Minimizes unscheduled downtime. Controller monitors machine mechanism
calibration values and process loop performance, indicating in advance
when machine maintenance should be scheduled.
Remote Diagnostics
Enables remote monitoring, trouble shooting and data logging of
an entire machine via a corporate intranet, or the Internet. Allows
for easy integration of information into enterprise software.
Object-Based Development
The BX controller features a sophisticated development environment
that can reduce new software development by 95%. Typical semiconductor
objects including robots, notch aligners, wafer cassettes, and pod
door openers are modeled in the BX development environment, reducing
the software effort to mainly application configuration and scheduling.
Detailed Specifications
The BX controller
packs motion control, I/O logic, process control, servo drives,
communications and more, into a form factor that could fit in your
desk drawer. Combine integrated drive power and E-Stop circuitry,
I/O, and control in this form factor and the result is a dramatic
savings in panel space, not too mention the integrated servo drives.
The BX controller delivers complete machine control in a box.
