ORION Ethernet
I/O Overview
ORION
supports a variety of popular Ethernet I/O products in motion control
applications. Fully integrated software includes elegant setup,
configuration and programming tools to greatly simplify using Ethernet
I/O.

Utilizing ORMEC’s Ethernet I/O
communications MBX, users can select from among:
to meet
specific application requirements.
With the Ethernet I/O MBX installed, the
Ethernet I/O modules are configurable from the development system using
MotionDesk. All I/O mapping and communications are
handled by the MBX, and the programmer can utilize standard MotionBASIC
statements (DIO@ and AIO@) to integrate analog and digital Ethernet I/O
into their application program.
Ethernet I/O Approaches
Since different I/O vendors have
designed their products to address differing customer needs, ORMEC is
supporting multiple Ethernet I/O products. The MBX is designed to support
a growing number of Ethernet I/O solutions in the future. Vendors
have taken two approaches to meeting the user’s Ethernet I/O needs:
"Modular I/O" combines a
rack and controller for each node. The user can mix and match module types
(AC In/Out, DC In/Out, sinking/sourcing, Analog current/voltage, etc.)
within the rack. Modular I/O provides maximum flexibility when there is a
need to mix I/O types and provides a solution for small numbers of
distributed I/O. WAGO Ethernet I/O and Opto22 Snap Ethernet I/O are
examples of modular I/O.
"Brick I/O" are enclosed
modules which contain both inputs and outputs, but the "type" is
fixed. For example, some options include 16 DC inputs (10-32V) plus 16 DC
outputs (10-32V) or 10 DC inputs (24V) and 8 relay outputs. Depending on
the mix of I/O required for your application, the "brick I/O"
approach may be an attractive and cost-effective solution. Modicon
TSX Momentum and Sixnet EtherTrak are examples of "brick I/O"
solutions.
Performance
The Ethernet I/O MBX has been optimized
for I/O handling --- running as a priority task under MotionBASIC to
maximize data throughput. The performance of Ethernet I/O is very
deterministic if it’s on an isolated network or separated from other
network traffic by a switching hub. MotionBASIC supports multiple Ethernet
adapters in the same controller to ease creating a separate I/O network.
Standard Ethernet Hardware
A key advantage of ORMEC’s approach
is it allows the system designer to utilize off-the-shelf Ethernet
adapters, cabling and network hubs and/or switches. The ORION
controller provides a PC-AT bus with up to seven expansion slots and a PC
card slot which can be used for Ethernet connectivity.
Advantages of Using
ORION Ethernet I/O
On the Software Side ...
- Tightly integrated with MotionDesk
development software and MotionBASIC to simplify application
programming.
- Flexibility to utilize either WAGO
Ethernet I/O, Opto22 Snap Ethernet I/O, Modicon TSX Momentum or Sixnet
EtherTrak hardware.
- Use Ethernet TCP/IP for both I/O and
development communications.
- WebTools software provides capability
to monitor I/O remotely using web browser.
On the Hardware Side ...
- Select the "best of breed"
Ethernet I/O hardware best suited to your application.
- Utilize cost effective Ethernet
adapters, either ISA or PC Card adapters to interface to the ORION
controller.
- Standard cabling is cost-effective
and provides distances up to 500 ft.
- Cost-effective hubs provide tools to
create effective machine control networks and limit network traffic.
