YOKOGAWA FA-M3 Series Basic Modules

Series Overview

The FA-M3 series is Yokogawa's "Range free Multi controllers". The basic modules covered in the document are the core hardware used to build the system, including the base module (carrying various functional modules), power module (power supply core), sequence CPU module (control core), and ROM storage module (program/data storage). The modules need to be matched according to specifications to jointly support high-speed sequence control, data processing, and network communication requirements in industrial scenarios.

4. Indicator lights and fault diagnosis

All CPU modules distinguish fault levels through front LED:

RDY (green): Off indicates hardware failure (such as CPU/memory error, unable to run);

RUN (green): Constant light indicates that the program is running, flashing indicates that it is stopping;

ALM (yellow): Always on indicates minor errors (such as communication abnormalities, the program can continue to run);

ERR (red): Always on indicates a serious error (such as program error, I/O module failure, program cannot run).

The network enhanced version also has SD (storage card status), EXE (intelligent access status), and US1/US2 (user-defined) indicator lights.

ROM storage modules (ROM packs)

Uniform size: All modules have a height of 100mm, with width differentiated by model (such as CPU/small power module 28.9mm, large power module 58mm), and a depth of approximately 83.2mm (excluding protrusions).

Environmental consistency: All modules work at a temperature of 0-55 ℃, store at a temperature of -20-75 ℃, and have a humidity of 10-90% RH (non condensing). They should be kept away from corrosive gases and dust.

Programming tool compatibility: Both require the use of FA-M3 programming tool WideField3 (SF630-MCW R2.01 and above versions) for configuration and debugging.
