1: Overview
Introduction
The SNAP PAC S-series programmable
automation controllers provide powerful,
real-time control and communication to meet
your industrial control, monitoring, and data
acquisition needs. As part of the Opto 22 SNAP
PAC System, one of these compact, industrially
hardened controllers can handle multiple
control, automation, and data acquisition tasks
involving digital and analog control, serial string
handling, PID, and enterprise connectivity.
Connecting to Opto 22 serial- and
Ethernet-based I/O systems, a SNAP PAC
S-series controller runs control programs written
in Opto 22’s PAC Control
™
software to monitor
and control a wide range of devices and
equipment. SNAP PAC S-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.
A SNAP PAC S-series controller simultaneously runs up to 32 PAC Control flowcharts, although a
PAC Control strategy can actually contain a much larger number of flowcharts. The total number of
flowcharts is limited only by the controller memory available for strategy storage.
Ethernet Communication
All SNAP PAC S-series programmable 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 S-series
controllers include two 10/100 Mbps Ethernet interfaces for networking through
an Ethernet switch to Ethernet hosts, as well as SNAP PAC brains and I/O, which provide local
intelligence and the connections to digital and analog sensors and actuators as well as serial devices.
