Description
The SNAP-LCE Ethernet-based, stand-alone industrial controller is
designed for use with Opto 22’s ioControl™ Basic software, part of
the ioProject™ Basic software suite.
Please note that SNAP-LCEs
and ioProject are not recommended for new development.
The last released version of ioProject Basic is version 7.1. This
software will remain available on our website for some time to
support customers who have existing SNAP-LCE controllers.
For
new development, we recommend SNAP-PAC controllers
(either standalone or on-the-rack) and PAC Project software.
See form #1688, the SNAP PAC System Migration Technical Note, for
guidelines on mixing older and newer hardware and software.
The SNAP-LCE provides real-time control and communication to
SNAP Ethernet-based input/output (I/O) systems and computer
networks. Independently running a control program you build with
the included ioControl development software, the SNAP-LCE
monitors and controls all kinds of devices and equipment. It also
communicates data about these devices and equipment directly to
Opto 22’s ioDisplay™ and third-party human-machine interfaces
(HMIs), to databases, and to other information technology (IT)
systems.
The controller communicates over standard TCP/IP Ethernet
networks at 10 or 100 Mbps. It can be attached to existing wired or
wireless Ethernet networks or be used in an independent control
network built with standard, off-the-shelf Ethernet hardware.
Communication with a SNAP-LCE controller can also be established
via a modem connection using Point-to-Point Protocol (PPP), with
firmware version 5.1c and newer. Wireless or wireline modem
connections are ideal for remote locations where an Ethernet
network is not practical.
The SNAP-LCE controller includes a 10/100 Mbps Fast Ethernet port
for networking through an Ethernet switch to SNAP Simple, SNAP
Ethernet, and SNAP Ultimate I/O units, which provide the
connections to digital and analog sensors and actuators as well as
serial devices. (Please note that SNAP Simple, Ethernet, and
Ultimate I/O units have been replaced by SNAP PAC I/O units.)
The controller also includes two serial ports for use with a modem
connection using PPP or for general-purpose communication with
serial devices (requires firmware version 5.1c or newer). Using this
option, you can send and receive data from one or two serial
devices connected directly to the controller, rather than requiring a
SNAP serial communication module on an attached I/O unit. Your
ioControl strategy controls communication with the devices and
uses the data as needed in control logic. Note that these two ports
are not isolated from each other.
The SNAP-LCE simultaneously runs up to 16 ioControl flowcharts,
plus the host task. The control strategy can contain a much larger
number of flowcharts, however; the total number is limited only by
the 8 MB of controller memory available for strategy storage.
Since the SNAP-LCE and the I/O units it controls have IP addresses
like other devices on an Ethernet network, the number of points the
controller can address is theoretically unlimited. The SNAP-LCE can
control many SNAP Ethernet-based I/O units. Because the controller
scans I/O only when your strategy logic requests it, the exact
number of I/O points it can scan—and the scanning
performance—depend on the architecture of your strategy.

Software
The SNAP-LCE controller is compatible with Opto 22’s ioProject
Basic software suite, which consists of three components:
•
ioControl Basic
—a graphical, flowchart-based programming
tool for machine control and process applications. Using ioCon-
trol, you create, download, and run control programs on the
SNAP-LCE controller. In addition to flowchart programming
(with subroutine capability), ioControl includes a powerful,
built-in scripting language based on C and other procedural
languages.
•
ioDisplay Basic
—an intuitive HMI package for building oper-
ator interfaces for your Microsoft® Windows®-based clients
communicating with a SNAP-LCE controller. ioDisplay offers a
full-featured HMI including alarming, trending, and a built-in
library of 3,000 industrial automation graphics.
•
ioManager
™—a utility application used to assign an IP
address to the SNAP-LCE, read or change basic controller con-
figuration, and more. In addition, you can use ioManager to
configure the I/O units that communicate with the controller
and to read from or write to I/O units.
ioProject Basic is included on the CD that comes with the SNAP-LCE
controller and is also available for download from our website at
www.opto22.com. For communication using OLE for Process
Control (OPC), you can purchase OptoOPCServer™, Opto 22’s OPC
2.0-compliant server, separately.

Products
Opto 22 develops and manufactures reliable, flexible, easy-to-use
hardware and software products for industrial automation, remote
monitoring, and data acquisition applications.
SNAP PAC System
Designed to simplify the typically complex process of
understanding, selecting, buying, and applying an automation
system, the SNAP PAC System
consists of four integrated
components:
•SNAP PAC controllers
•PAC Project™ Software Suite
•SNAP PAC brains
•SNAP I/O™
SNAP PAC Controllers
Programmable automation controllers
(PACs) are multifunctional, multidomain,
modular controllers based on open standards and
providing an integrated development environment.
Opto 22 has been manufacturing PACs for many years. The latest
models include the standalone SNAP PAC S-series and the rack-
mounted SNAP PAC R-series. Both handle a wide range of digital,
analog, and serial functions and are equally suited to data
collection, remote monitoring, process control, and discrete and
hybrid manufacturing.
SNAP PACs are based on open Ethernet and Internet Protocol (IP)
standards, so you can build or extend a system without the expense
and limitations of proprietary networks and protocols.
PAC Project Software Suite
Opto 22’s PAC Project Software Suite provides full-featured and
cost-effective control programming, HMI (human machine
interface) development and runtime, OPC server, and database
connectivity software to power your SNAP PAC System.
These fully integrated software applications share a single tagname
database, so the data points you configure in PAC Control™ are
immediately available for use in PAC Display™, OptoOPCServer™,
and OptoDataLink™. Commands are in plain English; variables and
I/O point names are fully descriptive.
PAC Project Basic offers control and HMI tools and is free for
download on our website, www.opto22.com. PAC Project
Professional, available for separate purchase, adds OptoOPCServer,
OptoDataLink, options for Ethernet link redundancy or segmented
networking, and support for legacy Opto 22 serial mistic™ I/O units.
SNAP PAC Brains
While SNAP PAC controllers provide central control and data
distribution, SNAP PAC brains provide distributed intelligence for
I/O processing and communications. Brains offer analog, digital,
and serial functions, including thermocouple linearization; PID loop
control; and optional high-speed digital counting (up to 20 kHz),
quadrature counting, TPO, and pulse generation and measurement.
SNAP I/O
I/O provides the local connection to sensors and equipment.
Opto 22 SNAP I/O offers 1 to 32 points of reliable I/O per module,
depending on the type of module and your needs. Analog,
digital, serial, and special-purpose modules are all mixed on
the same mounting rack and controlled by the same processor
(SNAP PAC brain or rack-mounted controller).
Quality
Founded in 1974 and with over 85 million devices sold,
Opto 22 has established a worldwide reputation for high-
quality products. All are made in the U.S.A. at our
manufacturing facility in Temecula, California. Because we
do no statistical testing and each part is tested twice before leaving
our factory, we can guarantee most solid-state relays and optically
isolated I/O modules for life.
Free Product Support
Opto 22’s Product Support Group offers free, comprehensive
technical support for Opto 22 products. Our staff of support
engineers represents decades of training and experience. Product
support is available in English and Spanish, by phone or email,
Monday through Friday, 7 a.m. to 5 p.m. PST.
Free Customer Training
Hands-on training classes for the SNAP PAC System are offered at
our headquarters in Temecula, California. Each student has his or
her own learning station; classes are limited to nine students.
Registration for the free training class is on a first-come, first-served
basis. See our website, www.opto22.com, for more information or
email training@opto22.com.
Purchasing Opto 22 Products
Opto 22 products are sold directly and through a worldwide
network of distributors, partners, and system integrators. For more
