YOKOGAWA FA-M3 Series Basic Modules

I/O response and scanning: The sensor control function supports dual scanning (main scan+sub scan), with an I/O response of up to 200 μ s; The constant scanning time can be adjusted from 1ms to 190ms.

Diagnosis and maintenance: Self check memory/CPU/I/O errors, with 64 error log records; Support debugging functions such as forced set/reset and online editing; Circuit annotations and tag names can be stored to improve maintenance efficiency.

(2) Network enhanced exclusive features (F3SP71-4S/F3SP76-7S)

Network Protocol: Supports TCP/IP, UDP/IP socket, FTP client/server, Modbus/TCP slave, advanced link services, and remote programming.

Storage Expansion: Built in 4MB RAM disk, supports SD memory card (maximum 32GB, FAT16/32 format, compatible with PC reading); Support the "virtual directory" function, which can read and write device data or programs through FTP.

Security and Logging: User authentication and permission management to prevent accidental operations; Record all CPU operations in the operation log for easy traceability; Network filters restrict communication access.

Hardware interface: Front mounted MODE rotary switch (for non PC maintenance, such as program loading), SD card slot, MiniB USB port, and 10/100BASE-TX Ethernet port.

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)

1. Core functions and positioning

Provide program and data storage for F3SP22-0S CPU module (network enhanced CPU uses SD card, incompatible with ROM module), which can store program control information, configuration data, timer/counter preset values, and annotation information.

2. Key specifications

Model compatible CPU, storage capacity (F3SP22-0S), data register storage, size (mm)

RK33-0N F3SP22-0S, 56K steps (actual program limit is 30K steps), 1024 words, 43 × 19 × 17.5

RK73-0N F3SP22-0S, 120K steps (actual program limit is 30K steps), 1024 words, 43 × 19 × 17.5

3. Usage restrictions

Only compatible with F3SP22-0S, not suitable for network CPUs such as F3SP66-4S and F3SP71-4S;

Data needs to be written using the FA-M3 programming tool (WideField3), which supports program solidification to prevent tampering.

Key points for module adaptation and installation

1. Adaptation relationship

Base - Power supply: 4/6 slot base (F3BU04/06) with F3PU10/16 series; 5/9/13/16 slot base (F3BU05/09/13/16) with F3PU20/26/30/36 series.

Base CPU: All bases can be equipped with F3SP22-0S/F3SP71-4S/F3SP76-7S, which can be used as an "additional CPU" when installed in slots 2-4.

CPU - Storage: F3SP22-0S with RK33/73 ROM module; F3SP71/76 with SD card (32GB max).

2. Installation and environmental requirements

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.
