1: Overview
INTRODUCTION
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 and
exchange 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.
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.
Several 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 standard and high-density), and serial modules. Full digital functions include
high-speed counting; quadrature counting; and pulse, period, and frequency measurement. The -FM and
-B models are 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, standard
and high-density digital, and serial modules. High-speed digital functions are not included. The -FM
model is Factory Mutual approved.
The -W model adds wireless LAN capability (see
for more
information).
