To stay competitive, today’s OEM machine builders must provide equipment that is ready to support analytics and give end users competitive advantage through increased efficiency, speed, and quality. However, as builders develop innovative solutions for material handling, life sciences and more, they can struggle to program and deliver machine control systems on time and within budget with the performance, security and flexible connectivity customers require.  


A new family of compact programmable automation controllers (PACs) helps original equipment manufacturers (OEM) successfully meet customer requirements by minimizing the need for specialized software engineering talent. Emerson’s release of its PACSystems RSTi-EP CPE200 controllers will deliver large programmable logic controller (PLC) capability in a small, cost-effective, IIoT-ready form factor so machine manufacturers do not need to sacrifice performance for price.

The CPE200 series solves these problems with security-by-design, open programming, and open communications built in to simplify connectivity to external analytics software platforms while reducing cost and complexity for OEMs and end users.


“Gaining competitive edge in today’s marketplace means having the flexibility to connect to the wide array of equipment end users employ as part of their proprietary processes, and supporting secure, open connectivity to allow easy access to on-premises and cloud-hosted analytics platforms,” says Jeff Householder, president of Emerson’s machine automation solutions business. 

The RSTi-EP system is designed for industrial internet applications with modular, plug-and-play connectivity and high channel density. The RSTi-EP station is meant to be installed horizontally on a DIN rail; vertical positioning is also possible but that reduces heat dissipation, which changes the derating values.

It is an I/O solution for stand-alone and networked PLC control systems for a variety of applications, including: equipment skid control, pumps management, material handling, basic machine safety, and conveyance systems.


The controllers offer open communications through native, pre-licensed support for OPC UA Secure and other common industrial protocols for flexible connectivity over high-speed Gigabit Ethernet. IEC 61131 programming languages and C, the world’s most popular and easiest-to-use programming language, help engineers write and run the high-performance algorithms that enable proprietary production strategies and advanced automation technologies. 

“The CPE200 series controllers take advantage of Emerson’s cybersecure-by-design architecture, common programming capabilities, and IIoT readiness to provide options currently missing in legacy compact PLCs,” adds Householder.
