Memory Architecture: The FX3GA-40MR-CM / FX3GA-40MT-CM utilizes a high-capacity memory map with 8,000 data registers and 4,096 state relays, enabling complex sequential and data-intensive applications. The extensive EEPROM latching (e.g., 1,152 auxiliary relays, 972 data registers) ensures critical process data is retained without a backup battery.
High-Speed Processing: With 21 high-speed counters, including 5 two-phase counters capable of 30 kHz, this module excels in applications like encoder feedback, speed measurement, and precise positioning. The interrupt inputs (6 points) provide immediate response to critical events.
Timer and Counter Flexibility: The 320 timers span three time bases (100 ms, 10 ms, 1 ms), allowing fine-tuned control for everything from simple delays to high-speed pulse timing. The 235 counters include 16-bit and 32-bit options for both simple and high-resolution counting tasks.
Real-Time Clock: The integrated RTC tracks year, month, day, hour, minute, second, and day of the week, enabling time-stamped data logging, scheduled maintenance, and event-driven control without an external clock module.
Expandable I/O and Memory: While the base unit offers 40 I/O points, the FX3GA series supports extension modules for I/O expansion, and the 24,000 extension registers (R0–R23999) and file registers (ER0–R23999) provide ample space for recipe storage, lookup tables, and data logging.
