M4RTU/M4 I/O User’s Guide
INTRODUCTION
BASIC ARCHITECTURE
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 80C 196 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 block diagram of the M4RTU/M4 I/O is shown in Figure 1-6.

The powerful two-processor architecture allows the main processor to off-load onto the I/O processor such
tasks as counting, frequency and pulse measurement, latching, totalizing, time proportional output control,
pulse generation, linearization, ramping, engineering unit conversion, averaging, peak and valley measurement,
PID control, and event/reactions, to name a few. I/O control can continue even if the main processor fails or
needs to be reset.
Sophisticated reset circuitry and watchdog timer capability permit a user to develop intelligent, robust error
recovery.
Finally, the M4BUS lays the foundation for intelligent coprocessor daughter cards. Armed with a processor,
these daughter cards have the capability to interface to various industry hardware and software protocols
without degrading overall real-time performance.
