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.
