GE’s PACSystems RSTi Standards-Based Distributed I/O Delivers High Performance and System Flexibility

  • PROFINET connectivity provides high-speed I/O
    throughput with connectivity to hundreds of third-party devices
  • Leverages GE’s expertise in automation and ruggedized
  • Simplifies system design without sacrificing
    performance to meet the needs of the Industrial Internet

Platforms (NYSE: GE) today announced the availability of its PACSystems® RSTi, a new, innovative standards-based granular machine
I/O integrated with the company’s PACSystems controllers on PROFINET that meets
the needs of the Industrial Internet. The RSTi is
based on global standards and delivers on the PROFINET promise of a consistent
and standard high performance communication link between field I/O and
controller. The unit’s integration into
the control system also simplifies development and commissioning that results
in increased productivity.

RSTi family of PROFINET-based granular I/O is part of GE Intelligent Platforms’
High Performance Platform that leverages industry standards as well as the
company’s experience in embedded technology and automation to deliver long-life
higher performance solutions that are easy to configure, manage and upgrade.

“The RSTi, like all of our new control solutions, is based on open
standards, leveraging our expertise in automation and ruggedized computing to
meet the needs of the Industrial Internet,” said Bill Black, Controllers
Product Manager for GE Intelligent Platforms. “In designing our distributed
network architecture GE set a goal of making distributed I/O configuration and
operation as simple as traditional rack-based systems. With the introduction of
RSTi this capability is extended to an entire new range of applications that
benefit from the combination of a wide range of high-density, small form-factor
I/O types.”

The RSTi provides simplified installation by
placing the granular I/O closer to the field devices using standard Ethernet
cabling. The distributed nature of the unit
provides the flexibility to expand and reconfigure field devices without
impacting control-to- device wiring unlike centralized control systems that
require new wiring to be installed back to the central control cabinet, thereby
lowering the total cost of ownership by reducing the high cost of field
wiring. OEMs can build machines in
sections with local I/O drops which can easily be assembled at the customer
site, connected to the controller by a high performance network, one standard
Ethernet cable versus hundreds of wires.
And, the compact size will be attractive to equipment builders and end
users alike because it allows the modules to be closer to the control devices
and therefore reduces wiring and hardware cost.

builders are continuously looking for ways to improve the performance of their
equipment while augmenting usability and reducing size and complexity,”
continued Black. “These requirements extend to the control system. With PACSystems
