Description
The affordable and compact SNAP PAC R-series
programmable automation controllers provide powerful, real-
time control and communication to meet your industrial
control, monitoring, and data acquisition needs. Part of the
Opto 22 SNAP PAC System™, the R-series PAC is a rack-
mounted, industrially hardened unit that can handle multiple
tasks involving digital and analog control, serial string
handling, communication, and enterprise connectivity.
Used with the included PAC Project Basic software suite (or
PAC Project Professional, purchased separately), the Ethernet-
based SNAP PAC R-series controller runs control programs
written in Opto 22’s PAC Control™ software. It can monitor and
control a wide range of devices and equipment wired to the
I/O on its own rack and to I/O on distributed racks equipped
with SNAP PAC EB-series brains. Alternatively, the R-series
controller can be used as a slave to a larger, SNAP PAC S-series
standalone industrial controller or a SoftPAC™ software-based
controller for PC-based control.
SNAP PAC R-series controllers are well suited to original
equipment manufacturers (OEMs), system integrators, and
end-users in process control, discrete manufacturing, or hybrid
industries and applications.
Seven models are available:
•
SNAP-PAC-R1
,
SNAP-PAC-R1-FM
,
SNAP-PAC-R1-W, and
SNAP-PAC-R1-B
each control a mix of SNAP analog,
digital (both 4-channel and high-density), and serial
modules. Full digital functions include high-speed
counting; quadrature counting; and pulse, period, and
frequency measurement. The -FM model is Factory
Mutual approved. The -W model adds wireless LAN
capability (see “Wired+Wireless Communication” on
page 2 for more information). The -B model is designed
to mount on SNAP B-series racks so that older I/O units
can be easily upgraded to a newer controller.
•
SNAP-PAC-R2
,
SNAP-PAC-R2-FM
, and
SNAP-PAC-R2-W
also control a mix of SNAP analog, 4-channel and high-
density digital, and serial modules. High-speed digital
functions are not included. The -FM model is Factory

capability (see page 2 for more information).
Built-in functions and comparisons of the SNAP-PAC-R1 and
SNAP-PAC-R2 are shown in the table on page 10.
Ethernet Communication
All SNAP PAC R-series controllers communicate over standard
10/100 Mbps Ethernet networks and can be attached to an
existing network. The controllers can also be used in an
independent control network built with standard, off-the-
shelf Ethernet hardware.
SNAP PAC R-series controllers include two 10/100 Mbps
Ethernet interfaces for networking to Ethernet hosts and to
other I/O units. These independent Ethernet ports have
separate IP addresses that can be used with PAC Project™
Professional software to set up redundant network links to
safeguard the availability and reliability of an I/O system, or to
segment a control system’s network from the enterprise LAN.
Supported protocols over Ethernet include EtherNet™/
IP, Modbus®/TCP, SMTP, SNMP, FTP, and OptoMMP.
Wired+Wireless Communication
SNAP-PAC-R1-W and SNAP-PAC-R2-W controllers
add wireless capability to communications. In addition
to the two wired network interfaces, these models have
a wireless network interface as well, so each PAC has a
total of three separate IP addresses—two wired and
one wireless. Wired+Wireless PACs can be used
wirelessly or on a wired network, or both at once.
For flexibility in designing your wireless network,
wireless communication includes support for
802.11a, b, and g standards.
Wired+Wireless PACs can be used with
a variety of wireless switches and other
infrastructure hardware. For the best
security, the 802.11i WPA2/AES standard
is supported, while older WPA and WEP
security standards are included for
backwards compatibility.
Because wireless functionality is in the
PAC itself, no additional parts are required
within the control system for wireless
use. All SNAP PAC racks and SNAP I/O
modules can be used either wired or
wirelessly. You can switch from one network to
the other without reconfiguring I/O or changing
field wiring.
Just like a laptop computer with a wireless connection, all
functionality remains the same whether the Wired+Wireless
PAC is used wirelessly or as part of a wired network. Supported
protocols remain the same. And control programs run the
same on both networks without reprogramming.
Serial Communication
SNAP PAC R-series controllers provide an RS-232 serial link to
support Point-to-Point Protocol (PPP) modem connections—
for creating TCP/IP networks over serial or PSTN (Public
Switched Telephone Network) lines—as well as remote serial
device communication.
The RS-232 serial interface supports either a modem
connection using PPP or general-purpose communication
with serial devices, allowing you to send and receive data from
a serial device connected directly to the controller. For
additional serial interfaces, you can add one or more SNAP
serial communication modules on the rack.
NOTE: The R-series controller does not include an RS-485 port and
cannot be used to control Opto 22 serial I/O processors, such
as the SNAP PAC SB-series brains. Use an S-series controller for
serial brains.
I/O Mounting Racks
SNAP PAC R-series controllers must be connected to the
appropriate rack to avoid damage to the controller. Both
the SNAP-PAC-R1 and R2 are designed to work with SNAP
PAC mounting racks, which are available with 4, 8, 12, or
16 positions for Opto 22 SNAP I/O modules. Part
numbers are SNAP-PAC-RCK4, SNAP-PAC-RCK8,
SNAP-PAC-RCK12, and SNAP-PAC-RCK16.
Factory Mutual-approved versions of these
racks, with part numbers ending in -FM,
are also available.
Ethernet PAC for Legacy I/O Racks
The SNAP-PAC-R1-B is a PAC-R1 for use
with older SNAP B-series racks. This PAC
provides an upgrade path from legacy
brains and rack-mounted controllers such
as the B3000, SNAP-B3000-ENET, or SNAP-
UP1-ADS that use B-series racks. See the
SNAP B-series Racks data sheet (form 0784)
for more information.
The SNAP-PAC-R1-B uses the same firmware and
has the same functionality as the SNAP-PAC-R1,
except that 4-channel digital modules can be
placed only in slots 0-7 due to limitations on the rack.

SNAP I/O
The SNAP PAC R-series controllers support all SNAP I/O
modules available on our website. SNAP digital I/O modules
contain four input or output points, and SNAP high-density
digital modules contain 16 or 32 input or output points. SNAP
analog modules contain 2 to 32 points, depending on the
module.
Software
SNAP PAC controllers use Opto 22’s PAC Project Microsoft®
Windows®-compatible automation software for programming,
human-machine-interface (HMI) development, and OPC
connectivity.
Two versions of PAC Project are available:
•PAC Project Basic includes PAC Control™ for developing
control programs, PAC Display™ for creating operator
interfaces, and PAC Manager™ configuration software.
• PAC Project Professional adds expanded versions of
PAC Control and PAC Display plus a SoftPAC software-
based controller for PC-based control, OptoOPCServer™
software for exchanging data with OPC 2.0-compliant
client software applications, and OptoDataLink™ for
exchanging SNAP PAC System data with databases
(including Microsoft SQL Server, Microsoft Access, and
MySQL), text files, and email systems).
PAC Control Basic is a graphical, flowchart-based
programming tool for machine control and process
applications. Using PAC Control, you create, download, and
run strategies on a SNAP PAC controller. In addition to
flowchart programming with subroutine capability,
PAC Control includes a powerful, built-in scripting language
based on C and other procedural languages.
PAC Control Professional adds the ability to import legacy
OptoControl strategies, support for older mistic™ serial I/O
units, and support for the dual independent Ethernet ports on
a SNAP PAC controller.
A SNAP R-series controller simultaneously runs up to 16
PAC Control flowcharts, although the PAC Control strategy can
actually contain a much larger number of flowcharts. The total
number of flowcharts is limited only by the memory available
for strategy storage.
PAC Display Basic is an intuitive HMI package for building
operator interfaces, or projects, for communicating with a
SNAP PAC controller. PAC Display offers a full-featured HMI
including alarming, trending, and a built-in library of 3,000
industrial automation graphics.
PAC Display Professional adds the ability to import projects
created in OptoDisplay, part of the legacy Opto 22
FactoryFloor® software suite, and using redundant Ethernet
communication links on SNAP PAC controllers. PAC Display
Professional can also connect to Ethernet-based FactoryFloor
controllers running OptoControl strategies.
SoftPAC is a software-based programmable automation
controller (PAC)designed for PC-based control. Programmed
just like an Opto 22 hardware PAC, SoftPAC runs your PAC
Control strategy independently on an embedded or
standalone PC. SoftPAC takes advantage of a PC’s speed and
file capabilities for applications requiring extended file storage,
frequent access to files, math-intensive processes, or a large
number of control flowcharts running at the same time.
OptoOPCServer is a fast, efficient OPC 2.0-compliant server
for communicating with many Opto 22 products, including
SNAP PAC controllers and I/O units, plus legacy Opto 22
Ethernet-based controllers and I/O. Using OptoOPCServer, you
can consolidate data from all these Opto 22 systems into the
OPC client software of your choice, such as third-party HMI

databases, including Microsoft SQL Server, Microsoft Access,
and MySQL, as well as text files. The I/O points and strategy
variables already created in your PAC Control strategy are
automatically available for OptoDataLink to use for data
exchange.
PAC Manager is a utility application for assigning IP addresses
to SNAP PAC controllers and brains, reading or changing basic
controller configuration, and configuring and testing I/O.

PAC R-series controller running a PAC Control strategy.
The controller is also connected to a larger, separate
enterprise Ethernet network to provide data to PCs running
Opto 22’s PAC Display HMI software, OptoOPCServer, and
OptoDataLink. Sitting between the two networks, the SNAP
PAC R-series controller segments enterprise traffic from the
control network.
If you use a Wired+Wireless PAC (SNAP-PAC-R1-W or
SNAP-PAC-R2-W), one of these networks can be a wireless
LAN. See the following page for an example.
SNAP PAC R-series controller communicates with host computers through one network

This diagram shows two SNAP PAC R-Series controllers
functioning as I/O unit brains connected to two separate
Ethernet networks. This configuration addresses the concern
that an Ethernet network may fail or need maintenance,
leaving the PC running OptoOPCServer and OptoDataLink,
the PC running PAC Display, the controller, and the I/O units
unable to communicate.
In this configuration, if one network goes down, devices can
still communicate because the SNAP PAC R-series controllers
and the SNAP PAC S-series controllers both have two network
interfaces, and each PC in this system has two network
interface cards.
Using a Wired+Wireless PAC (SNAP-PAC-R1-W or

SNAP PAC System
Designed to simplify the typically complex
process of selecting 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, modular controllers based on open
standards.
Opto 22 has been manufacturing PACs for over two decades. The
standalone SNAP PAC S-series, the rack-mounted SNAP PAC R-
series, and the software-based SoftPAC™ all handle a wide range
of digital, analog, and serial functions for 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 easily, without the
expense and limitations of proprietary networks and protocols.
Wired+Wireless™ models are also available.
PAC Project Software Suite
Opto 22’s PAC Project Software Suite provides full-featured, cost-
effective control programming, HMI (human machine interface)
development and runtime, OPC server, and database connectivity
software for your SNAP PAC System.
Control programming includes both easy-to-learn flowcharts and
optional scripting. 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 one SoftPAC,
OptoOPCServer, OptoDataLink, options for controller 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, and serial 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, 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
test each product twice before it leaves our
factory, rather than only testing a sample
of each batch, we can guarantee most
solid-state relays and optically isolated I/O
modules for life.
Free Product Support
Opto 22’s California-based Product Support Group offers free,
comprehensive technical support for Opto 22 products. Our staff
of support engineers represents decades of training and
experience. Support is available in English and Spanish by phone
or email, Monday–Friday, 7 a.m. to 5 p.m. PST.
Additional support is always available on our website: how-to
videos, OptoKnowledgeBase, self-training guide, troubleshooting
and user’s guides, and OptoForums.
In addition, hands-on training is available for free at our Temecula,
California headquarters, and you can
register online
.
