IEEE 1394 Interface System: Super High-Speed
Field Bus for Servos and I/O Based on IEEE 1394 FireWire
Overview
The IEEE 1394 interface system is based on IEEE
1394 FireWire communications for high-performance, digital
network IEEE 1394 servo drives. IEEE 1394 servo drives are proven,
high-performing networked drives with fully automatic drive
commissioning and all-digital configuration, setup and operation.
These drives offer a power range from 600 to 15,000 watts, and users
can mix and match servo technologies — DC brushless rotary,
linear, DC brush-type or voice-coil motors —in the
same system.
The IEEE 1394 platform features simple connections
and cabling, superior diagnostics, elimination of all manual drive
adjustments (no pots or jumpers to set), and control flexibility
— all system parameters are configurable in the software package.
Soft Servo's IEEE 1394 platform provides an all-digital, minimal-hardware
control architecture for next-generation motion control/CNC.
FireWire Communications Technology
 FireWire,
defined by the IEEE 1394 standard, is a high-speed, high-bandwidth
digital-to-digital serial data bus protocol, supporting
both asynchronous & isochronous data transfer. FireWire was
designed for the multimedia needs of computer and consumer electronics
(including audio, imaging, video and other streaming data), which
mirror the requirements of servo drive applications: speed, networking
and self-configuration (Plug ’N’ Play).
IEEE 1394 Network Features
- Scalable — up to 16 axes of servo control, with users connecting
exactly the number of drives needed, and no more
- Data transfer rate of 200 Mbps
- 1 ms position feedback rate
- All-digital network eliminates digital to analog conversions
between the PC and drive systems.
- Daisy-chainable servo drives offer distributed control and multiple
nodes, with a total network length of up to 72 meters, allowing
distance between the PC, machine and peripherals
- Cost-effective, thin-wire, industry-standard FireWire cabling
requires no maintenance
- Simple wiring (a single cable) and only one interface card —
no additional proprietary hardware components are required
- Plug ’N’ Play IEEE 1394 networking allows for quick
changes to the system
- Supports absolute and incremental encoders
- Third-party devices, such as vision systems, can communicate
on the same network as the servo drives
- ServoWire Pro, an application suite of configuration, diagnostic
and maintenance utilities that runs on the host PC, assists in
the development and on-going support of IEEE 1394 interface systems
I/O
Ormec's IEEE 1394 drives provide software configurable drive I/O
that can be used to support a variety of functions required by machines.
 A
modular, fieldbus independent I/O system from Wago can be added
to the IEEE 1394 interface system. Each node is comprised of an
IEEE 1394 fieldbus coupler, up to 64 connected fieldbus modules
for any type of signal, and an end module.
An optional and affordable fiber-optic VersioBus
I/O network can also be included as part of the IEEE 1394 interface
system.
Hardware Connections in the
IEEE 1394 Interface System
Hardware in the IEEE 1394 Interface System
 Standard
IEEE 1394 Adapter Board
PCI adapter board for insertion in the host PC. Each
board provides an IEEE connector for a IEEE 1394 network.
The IEEE 1394 adapter card must be OHCI (Open Host Controller Interface) compliant.
 ISA,
PCI or PC104 VersioBus Adapter Boards
ISA, PCI or PC104 adapter boards for insertion in
the host PC. Each board provides a fiber-optic transceiver for the
I/O network, 32 points of on-board general I/O, and an encoder and
digital I/O connector for a handwheel.
The FP-80 is for an ISA slot, the FP-95 is for a PCI
slot, and the FP-104 has a PC104 stacking connector.

IM-300 Optional I/O Modules
The IM-300 is an optional 64-point general I/O module
with built-in wire-entry screw terminals and LEDs. It
requires a VersioBus adapter board to connect to a VersioBus I/O
network. Up to four IM-300s can be daisy-chained together
for distributed control and multiple nodes with VersioBus fiber
optics, to provide as many as 256 additional I/O points.

of the optional VersioBus I/O network.
