Big Features in a Compact Package

The small footprint VersaMax Micro PLC offers  the flexibility

of modular design and a variety of built-in features, including

up to 64 I/O points (expandable to 176 I/O points), fast cycle

times, a robust instruction set and extensive memory that

multiplies your programming options.

A Variety of Communications Options

All units have a RS-232 port that can be used for SNP slave,

Modbus RTU or serial I/O commands, and  select units have

an RS-485 port that adds SNP master and Modbus master

commands. The Micro 20. Micro 40 and Micro 64 also have a

second option port that supports either RS-232. RS-485 or USB

communications module. The VersaMax Micro  PLCs are easily

networked to Ethernet with the powerful VersaMax SE (Serial to Ethernet module).

Performance to Improve Productivity

The VersaMax Micro family is designed to provide the

power and performance of customized solutions with the

convenience and economy of off-the-shelf technology.

VersaMax Micro PLCs have two  channels of high-speed

control, two independent 65kHz pulse and direction outputs,

and user configurable inputs and outputs to effectively

increase machine performance. With VersaMax Micro PLCs

you  can reduce costs and save time on machine configurations

without compromising the ability to customize the features

that are right for your application.

Today’s manufacturing environment faces the

critical need for shorter production runs, quicker

changeovers, and just-in-time manufacturing.

Machines are no longer dedicated to a single

product and long production runs. VersaMax

Micro helps you address this challenge as a

scalable solution with precise and powerful

control in a compact design. With the flexibility

to enhance machine performance, availability,

and profitability, the modular VersaMax Micro

offers the features to match your application needs.

Application Flexibility and Scalability

VersaMax Micro PLCs  provide the scalability and flexibility

to cover a broad range of  applications. For applications that

require more I/O, up to four modules can be used to expand

the series of controllers. For smaller machines, units can be

used as a standalone controller with integrated I/O functions.

With I/O expansion modules and support of a portable

program FLASH memory module, the VersaMax Micro PLCs

provide the flexibility to configure a solution to your exact

requirements and budget.

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-configure

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 flexibility 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

configuration allows encrypted firmware updates to be

executed from a secure central location. And, a suite of

cybersecurity technology and tools help prevent unauthorized

updates.

Small Footprint. Big Impact.

Leverage the power and flexibility 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 simplifies training for operators and

maintenance workers and streamlines application development

and integration.

RSTi-EP CPUs support real-time application status, remote

diagnostics and:

nDual LAN interfaces with four Ethernet ports

nBuilt-in RS-232 serial port

nA range of communications protocols, including PROFINET

nAvailable DNP3 Outstation capability for Remote Terminal

Unit (RTU) applications

nUp to 1.5 MB of non-volatile user memory all in just 1.5”

(38.1mm) of DIN rail space

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.
