This connectivity with legacy serial-based I/O systems, combined with PAC Control Professional
software’s ability to import control programs (or
strategies
) written in OptoControl™ software,
provides a migration path to integrate older Opto 22 I/O systems into modern control hardware
running on Ethernet networks.
For detailed information on updating control strategies and integrating legacy control hardware into
modern systems, see the
FactoryFloor to PAC Project Migration Technical Note
(Opto 22 form 1692).
Software
SNAP PAC controllers use Opto 22’s
PAC Project
Microsoft
®
Windows
®
-compatible automation
software for programming, human-machine-interface (HMI) development, and OPC and database
connectivity. Two versions of PAC Project are available:
•
PAC Project Basic
includes PAC Control for developing control programs, PAC Display
™
for
creating operator interfaces, and PAC Manager
™
configuration software.
•
PAC Project Professional
adds expanded versions of PAC Control and PAC Display plus
OptoOPCServer
™
software for exchanging data with OPC 2.0-compliant client software
applications and OptoDataLink
™
for sharing SNAP PAC System data with ODBC-compliant
databases.
The PAC Project software suite includes the following applications:
•
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 capabilities to import OptoControl strategies, to support
mistic
I/O units, and to use a SNAP PAC controller’s independent Ethernet ports to segment
communication links.
•
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 Opto 22
FactoryFloor® software suite, and to use redundant communication links on SNAP PAC
controllers. PAC Display Professional can also connect to Ethernet-based FactoryFloor
controllers running OptoControl strategies or ioProject controllers running ioControl strategies.
•
OptoOPCServer
(PAC Project Professional only) is a fast, efficient OPC 2.0-compliant server for
communicating with many Opto 22 products, including SNAP PAC controllers running PAC
Control strategies, SNAP PAC brains, SNAP Ultimate controller/brains, SNAP Ethernet and SNAP
Simple brains, and Ethernet-based FactoryFloor controllers running OptoControl strategies.
Using OptoOPCServer, you can consolidate data from all these Opto 22 systems into the OPC
client software of your choice, such as third-party HMI and data acquisition packages, and
custom software applications you create with tools such as Visual C++
