are SNAP-PAC-RCK4, SNAP-PAC-RCK8, SNAP-PAC-RCK12, and SNAP-PAC-RCK16. Factory Mutual-approved
versions of these racks, with part numbers ending in -FM, are also available.
Ethernet PAC for Legacy I/O Racks
The SNAP-PAC-R1-B is a PAC-R1 for use with older SNAP B-series racks (only B-series racks with a B in the part
number; not the SNAP-D64RS rack). This PAC provides an upgrade path from legacy brains and rack-mounted
controllers such as the SNAP-B3000-ENET or SNAP-UP1-ADS that use B-series racks. See the
data sheet (form 0784) for more information on racks.
The SNAP-PAC-R1-B uses the same firmware and has the same functionality as the SNAP-PAC-R1, except that
4-channel digital modules can be placed only in slots 0-7 due to limitations of the rack.
SNAP I/O
The SNAP PAC R-series controllers support all SNAP I/O modules available on our website. SNAP digital I/O
modules contain four input or output points, and SNAP high-density digital modules contain 16 or 32 input or
output points. SNAP analog modules contain 2 to 32 points, depending on the module.
PAC Project Software
PAC Project
SNAP PAC controllers use Opto 22’s
PAC Project™
, a Windows®-compatible automation software suite for
control system programming, human-machine-interface (HMI) development, and OPC connectivity.
Two versions are available: PAC Project Basic, a free to download from the
(
www.opto22.com
); and PAC Project Professional, available for purchase and download from our website.
•
PAC Project Basic
includes PAC Control™ for developing control programs, PAC Display™ for creating
operator interfaces, and PAC Manager™ configuration software. Documentation is also included.
•
PAC Project Professional
also includes PAC Manager, and adds expanded versions of PAC Control and
PAC Display, plus two more tools: OptoOPCServer
™
software for exchanging data with OPC 2.0-compliant
client software applications, and OptoDataLink
™
for exchanging SNAP PAC System data with databases
(including Microsoft SQL Server®, Microsoft Access®, and MySQL®), text files, and email systems).
Documentation is also included.
You can also purchase PAC Control Professional, PAC Display Professional, OptoOPCServer, and
OptoDataLink separately. For details, see the
(form 1699).
PAC Control Basic
is a graphical, flowchart-based programming tool for machine control and process
applications. Using PAC Control, you create, download, and run strategies on a SNAP PAC controller. In addition
to flowchart programming with subroutine capability, PAC Control includes a powerful, built-in scripting
language based on C and other procedural languages.
PAC Control Professional
adds the ability to import legacy OptoControl strategies, support for older
mistic™
serial I/O units, and support for the dual independent Ethernet ports on a SNAP PAC controller. A SNAP
R-series controller simultaneously runs up to 16 PAC Control flowcharts, although the PAC Control strategy can
actually contain a much larger number of flowcharts. The total number of flowcharts is limited only by the
memory available for strategy storage.
PAC Display Basic
is an intuitive HMI package for building operator interfaces, or
projects
, for communicating
with a SNAP PAC controller. PAC Display offers a full-featured HMI including alarming, trending, and a built-in
library of 3,000 industrial automation graphics.
PAC Display Professional
adds the ability to import projects created in OptoDisplay, part of the legacy
Opto 22 FactoryFloor
®
software suite, and using redundant Ethernet communication links on SNAP PAC
