on one mounting rack
Distributed intelligence for your SNAP PAC system

multidrop capability
Description
SNAP PAC brains are powerful and versatile I/O and network
communications processors for your SNAP PAC System
primarily to work in distributed systems controlled by a SNAP PAC
programmable automation controller, 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 are available for either Ethernet or serial network
communications.
• SNAP PAC EB brains communicate over a standard
10/100 Mbps Ethernet network.
• SNAP PAC SB brains communicate over an RS-485 serial net-
work, 2-wire or 4-wire, using a binary protocol.
EB Series Brains
Two SNAP PAC Ethernet Brains are available: the SNAP-PAC-EB1
and the SNAP-PAC-EB2. They 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 4.
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.

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
. Designed
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
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, serial, and
special-purpose input and output modules. SNAP PAC SB brains
support all SNAP analog and digital modules, plus the SNAP-AIPM
power-monitoring module.
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.
