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, serial, and
special-purpose 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.
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. These brains support EtherNet/IP
SNMP for network management, FTP for the brain’s built-in file
system, SMTP (email client), and Opto 22’s open memory-mapped
LEDs and Network Interfaces—Ethernet Brains

Switched Ethernet network
interfaces
Brains can be networked in a daisy-chain
configuration or in a standard star
configuration using either Ethernet
interface. Both interfaces use the same IP
address.
NOTE: When using a daisy-chain
configuration, be aware that if power to a
brain is lost, all brains beyond it on the
network will also lose communication.

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 suite comes in two forms, Basic and Professional.

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
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.

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
