all on one mounting rack
Distributed intelligence for your SNAP PAC system
Choose Ethernet or serial network connections, both
with multidrop capability, or choose a wireless LAN
Factory Mutual-approved Ethernet versions available
Description
SNAP PAC brains are powerful and versatile I/O and network
communications processors for your SNAP PAC System. They
are designed primarily to work in distributed systems
controlled by a SNAP PAC programmable automation
controller, but SNAP PAC Ethernet brains can also be used as
intelligent remote I/O in an Allen-Bradley® RSLogix®-based PLC
system or as PC-based I/O.
All SNAP PAC brains provide local intelligence that frees the
controller for supervisory tasks. For example, each brain
independently handles functions such as latching, counting,
thermocouple linearization, watchdog timers, and PID loop
control. These functions continue to work on the brain even if
communication with the controller is lost.
SNAP PAC brains can also be used independently for
standalone I/O processing and communication.
SNAP PAC brains use either Ethernet or serial networks.
SNAP PAC EB brains communicate over a standard
10/100 Mbps Ethernet network. EB-W brains also
communicate over a wireless LAN.
SNAP PAC SB brains communicate over an RS-485 serial
network, 2-wire or 4-wire, using a binary protocol.
EB Series Brains
SNAP PAC Ethernet Brains include the SNAP-PAC-EB1 and the
SNAP-PAC-EB2, both with Factory Mutual versions available
(indicated by -FM at the end of the part number). These brains
are identical in their functions and features except that the
SNAP-PAC-EB1 provides high-speed digital functions for use
with 4-channel digital I/O. The SNAP-PAC-EB2 does not offer
high-speed digital functions. For a complete list of brain
features, see page 6.
Each SNAP PAC EB brain is equipped with two switched
Ethernet network interfaces. Because these interfaces share a
single IP address and act just like an Ethernet switch, SNAP
PAC brains can be installed not only in a standard star
configuration, but optionally in a multi-drop configuration,
extending the control network without the expense of
additional Ethernet network hardware.
Wired+Wireless EB Brains
The SNAP-PAC-EB1-W and SNAP-PAC-EB2-W brains add a
wireless LAN interface as well. These brains can be used on a
wired network, on a wireless LAN, or both at the same time.
For flexibility in designing your wireless network, 802.11a, b,
and g standards are supported.

Wired+Wireless EB brains can be used with
Wired+Wireless SNAP PAC S-series and R-series
controllers and 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
brain itself, no additional parts are
required for wireless I/O processing or
communication. 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. All
features work the same on both networks. See the feature
chart on page 6.
SB Series Brains
The two SNAP PAC Serial Brains are the SNAP-PAC-SB1 and
the SNAP-PAC-SB2. Like the EB brains, the two SB brains are
identical except that the SNAP-PAC-SB1 provides high-speed
digital functions for use with 4-channel digital I/O. The SNAP-
PAC-SB2 does not offer high-speed digital functions. See
page 6 for a comparison of brain features.
I/O Processing
Each SNAP PAC brain mounts on a SNAP PAC rack with up to 4,
8, 12, or 16 SNAP I/O modules.
SNAP PAC EB brains support all SNAP analog, digital, and serial
input and output modules. SNAP PAC SB brains support all
SNAP analog and digital modules.
These modules can all be mixed on the same mounting rack
and placed in any position on the rack, to accommodate the
required mix of signals at any location. Each SNAP I/O module
provides from 1 to 32 I/O points, depending on the module.
The same racks and modules are used with Wired+Wireless EB
brains as with regular EB brains. No additional hardware is
needed for wireless communication.
For more information on mounting racks, see Opto 22 form
#1684, the SNAP PAC Racks Data Sheet. For more information
on SNAP I/O modules, visit our website at www.opto22.com.
Multiple Protocol Support on Ethernet
In addition to I/O processing, SNAP PAC Ethernet brains
support communication using multiple protocols running
simultaneously over Ethernet, including EtherNet/IP,
Modbus®/TCP, SNMP for network management, FTP for the
brains built-in file system, SMTP (email client), and Opto 22’s
open memory-mapped OptoMMP protocol. Communication
with OPC 2.0-compliant clients is available through
OptoOPCServer (see “Software, below).
Wired+Wireless EB brains support the same protocols over a
wireless LAN and on a wired Ethernet network.
Software
SNAP PAC brains are primarily designed for use with a SNAP
PAC programmable automation controller. The controller
runs a control program built with PAC Project software. The
PAC Project software suite comes in two forms, Basic and
Professional.
•PAC Project Basic, which is included in the purchase of
a SNAP PAC controller, consists of control programming,
human-machine interface (HMI) creation, and
configuration software.
PAC Project Professional is available for purchase and
adds OptoOPCServer for OPC connectivity,
OptoDataLink for database communications, and
additional features.
In addition to using a SNAP PAC controller with PAC Project
software, you can communicate with SNAP PAC brains using
the open and documented OptoMMP protocol. A free
OptoMMP Communication Toolkit is available on our website,
www.opto22.com. This toolkit includes ActiveX components
and C++ classes, so you can use programming tools such as
Visual Basic or Visual C++ to communicate with the brains.
See form #1465, the OptoMMP Protocol Guide, for more
information.
Ethernet brains can also communicate with Allen-Bradley
RSLogix® systems using EtherNet/IP (see Opto 22 form
#1770, the EtherNet/IP for SNAP PAC Protocol Guide, on our
website).
In addition, Ethernet brains communicate using Modbus/
TCP; see Opto 22 form #1678, the Modbus/TCP Protocol Guide,
for more information.

System Architecture
SNAP PAC brains are ideally suited for use as local I/O, logic,
and communication processors in distributed systems.
The system shown below is controlled by a SNAP PAC S-series
standalone controller running a PAC Control strategy. Some of
the distributed I/O units are on an Ethernet network using EB
brains, and some are on a serial network using SB brains. The
controller handles all I/O on both networks.
SNAP PAC Ethernet brains can also be used as intelligent
remote I/O with Allen-Bradley Logix PLC systems.
While the controller provides overall direction to the control
system, each SNAP PAC brain locally handles counting,
latching, thermocouple linearization, PID loop control, and
other functions for the I/O modules on the racks. These local
functions continue even if the controller loses
communication with the brains.

All functions remain the same no matter which network is
used, and if you change from wired to wireless or back again,
no changes are needed to I/O modules or field wiring.
The following diagram shows Wired+Wireless EB brains used

System Architecture (continued)
SNAP PAC Ethernet Brains offer two options for wired
networking. As shown in the diagram on page 8, they can be
networked in a standard star configuration using off-the-shelf
Ethernet network switches or routers.
As shown below, SNAP PAC Ethernet brains can also be
networked in a daisy-chain configuration, using the two
switched Ethernet interfaces on each brain.
In this diagram, a rack-mounted SNAP PAC R-series controller
runs the PAC Control strategy and controls the system. The
distributed brains are daisy-chained together, eliminating the
expense of additional routers or switches.
NOTE: A Wired+Wireless EB brain does not provide access to
dasiy-chained brains through its wireless LAN interface,
because that interface has a different IP address. Data can go
only through the wired interfaces, which use the same IP
address.

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.
