ABOUT THE M4RTU/M4 I/O
Thank you for purchasing an Opto 22 Modular M4RTU or M4 I/O Controller. The M4RTU/M4 I/O delivers the
functionality and robustness of a remote telemetry unit with the power of a distributed automation system, all
in one controller. The M4RTU/M4 I/O consolidates two powerful processors on a single processor board.
Program control and host communications are handled by a powerful 32-bit microprocessor, while another
processor handles I/O interfacing and control. This dual-processor board is combined with a digital/analog
I/O board, a 3-slot vertical expansion bus board (M4BUS), and a modular power supply into a compact aluminum
extrusion package that can be mounted horizontally or vertically. A complete line of modular adapter cards are
available, providing a wide range of communication options.

INTRODUCTION
OVERVIEW – M4RTU/M4 I/O REMOTE TELEMETRY UNIT
The M4RTU/M4 I/O combines the features and functions of a Remote Telemetry Unit (RTU) with the power of
a distributed automation system all in a single controller. The M4RTU/M4 I/O is the heart of Opto 22’s distributed
control hardware platform. This advanced hardware/software solution is built to be deployed in any type of
network or remote control environment. The M4RTU/M4 I/O was designed specifically for industrial field
applications, such as wastewater treatment, well monitoring, tank farms, substation automation, and gas/
petrochemical applications.
The M4RTU/M4 I/O is fully supported with FactoryFloor, Opto 22’s suite of Windows™32-bit software that
delivers total control to industrial automation customers. FactoryFloor consists of four integrated components:
•OptoControl™, a graphical, flowchart-based development environment for control solutions.
•OptoDisplay™, a graphical, multimedia operator interface package.
•OptoServer™, a robust data server that connects the controller network with the PC-based FactoryFloor
network.
•Plus OptoConnect™, a drag-and-drop database utility that makes building SQL Server and Access
databases a snap.
The M4RTU/M4 I/O is part of Opto 22’s Modular line of controllers. These units feature a powerful, yet easy-to-
use modular design that incorporates Opto 22’s M4 bus technology (M4BUS). This technology lets customers
tailor their controller and interface hardware to the scale of the project at hand. The M4BUS allows users to
create custom interface configurations by simply plugging in one or more of the modular interface cards. These
open options allow customers to share real-time plant floor data with telemetry or network-based control and
information systems. All modular interface cards for serial communications or network connectivity are supported
as standard selections in the FactoryFloor software.
CHAPTER 1

M4RTU/M4 I/O User’s Guide
The M4RTU/M4 I/O consolidates two powerful processors on a single processor board. Program control and
host communications are handled by a powerful 32-bit 68020 microprocessor, while a 16-bit 80C196 processor
handles I/O interfacing and control. This dual-processor board is combined with a digital/analog I/O board,
a 3-slot vertical expansion bus board (M4BUS), and a modular power supply into a compact aluminum extrusion
package that can be mounted horizontally or vertically
.
The M4RTU/M4 I/O base unit has two serial ports: RS-232 and RS-485/422. The RS-485/422 port can be used
to support I/O expansion using standard Opto 22 digital or analog I/O units. These serial ports can communicate
at up to 115 K baud, and the RS-485/422 port logically supports up to 4,096 remote I/O channels as a remote
bus.
The M4RTU/M4 I/O comes standard with 1 MB of battery-backed RAM and 256 KB of flash memory. The RAM
can be used to store a user’s control strategy (program) and data. The flash memory stores a kernel (operating
system) and can be used to store a user’s control strategy permanently. The use of flash technology throughout
the M4RTU/M4 I/O allows the user to remotely download new kernels offered by Opto 22. This avoids the
need to visit an M4RTU/M4 I/O site to download a new kernel that offers features required for a given application.
The M4RTU/M4 I/O base unit accommodates a total of eight digital and four analog Generation 4®(G4) I/O
modules. The G4 digital I/O modules provide optical isolation, come in a variety of DC and AC voltages, feature
an integral status LED as well as fused outputs, and offer an optional integral automatic/manual diagnostic
switch. The G4 analog I/O modules provide both optical and transformer isolation, eliminating ground loops
and channel-to-channel interference. Analog modules come in a variety of field input and output types, including
current loop, voltage, thermocouple, RTD, ICTD, and TPOs. Analog current modules include the option to power
the current loop, eliminating costly power supplies and wiring.
For safety and convenience, the M4RTU/M4 I/O has system monitors for temperature, AC operation, and low
battery, and includes such features as a real-time clock and watchdog timers. Removable connector technology
is integrated throughout the unit for easy maintenance and wiring removal. Expansion options are available for
adding I/O channels as well as for communicating with SCADA systems, industrial PCs, other controllers or
intelligent equipment devices.
