SNAP PAC R-Series Controllers

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

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

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.

Four models of the SNAP PAC R-series controller are available:

Features

SNAP-PAC-R1 and SNAP-PAC-R1-FM control a mix of SNAP

analog, digital (both standard and high-density), and serial

modules. Full digital functions include high-speed counting,

quadrature counting, pulse measurement, and period and fre-

quency measurement. The -FM model is Factory Mutual

approved.

SNAP-PAC-R2 and SNAP-PAC-R2-FM 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.

Rack-mounted industrial controller with I/O processor

included.

Two independent 10/100 Mbps Ethernet network

interfaces

One RS-232 port with handshaking, suitable for

modem communication using PPP

MicroSD card slot for removable data storage

Full-featured control and HMI software included

with purchase

Part Numbers

Built-in functions and comparisons of the SNAP-PAC-R1 and SNAP-

PAC-R2 are shown in the table on

Ethernet Communication

SNAP PAC R-series controllers communicate over standard 10/

100 Mbps Ethernet networks and can be attached to existing wired

or wireless Ethernet networks. 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

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

TCP, SMTP, SNMP, FTP, and OptoMMP.
