PACSystemsTM RSTi-EP Controllers
Programmable Automation Controller
The demand for improved asset performance and
productivity is increasing in manufacturing and
infrastructure markets. They require even smaller
applications with robust execution performance
and a range of connectivity options to real-time
application status information and diagnostics.
Emerson has designed a small form factor,
high performance controller that enables
equipment builders to improve performance and
flexibility of their machines while reducing size,
complexity, and cost.
Small Footprint. Big Impact.
Leverage the power and exibility of PACSystems in smaller
applications. RSTi-EP CPUs make it possible to incorporate
the entire PACSystems programming suite in stand-alone
applications or as auxiliary control in larger process applications
that use RX3i. This simplies training for operators and
maintenance workers and streamlines application development
and integration.
RSTi-EP CPUs support real-time application status, remote
diagnostics and:
n Dual LAN interfaces with four Ethernet ports
n Built-in RS-232 serial port
n A range of communications protocols, including PROFINET
n Available DNP3 Outstation capability for Remote Terminal
Unit (RTU) applications
n Up to 1.5 MB of non-volatile user memory all in just 1.5”
(38.1mm) of DIN rail space
Speaking the Same Language
With RSTi-EP CPUs you can use the same runtime as existing
RX3i controllers and leverage existing application libraries
and templates while scaling footprint and performance for
smaller application installations. Fast, easy-to-congure
PACSystems technology and an extensive range of I/O options
support scalable automation and highly distributed modular
machine designs.
PROFINET Advantage
PROFINET I/O solutions from Emerson can provide productivity
and performance advantages for virtually any type of control
application in a range of industries. PROFINET supports a
variety of I/O without compromising system performance
and can operate in high-noise environments. Connect to any
of Emerson’s purpose-built I/O families through a PROFINET
interface for advanced exibility and performance.
Advanced Security
Without proper cybersecurity in place, industrial controls
may be vulnerable to cyber threats. Emerson’s PAC, PLC
and industrial automation portfolio enlists defense-indepth
architecture to help secure assets from these threats.
RSTi-EP CPUs incorporate technologies such as Trusted
Platform Modules and secure and trusted boot. Centralized
conguration allows encrypted rmware updates to be
executed from a secure central location. And, a suite of
cybersecurity technology and tools help prevent unauthorized
updates.
