Panasonic AFP2720 FP2-MW Memory Cassette – High-Capacity Program Storage | FP2 Series PLC Platform
Engineering Background
The Panasonic FP2 Series represents one of the most robust mid-to-large scale PLC platforms in industrial automation, widely deployed across Asia-Pacific and global manufacturing facilities since the 1990s. Engineered under the NAIS/Panasonic Industrial Devices brand, the FP2 architecture is renowned for its modular expandability, high-speed scan cycles, and long-term parts availability — making it a preferred backbone for continuous-process and discrete manufacturing alike.
Product Positioning
The AFP2720 is a dedicated Memory Cassette (FP2-MW) designed to extend or replace the internal program memory of FP2 CPU units. It enables engineers to store larger ladder/instruction list programs, retain data across power cycles without battery dependency, and facilitate rapid program transfer during maintenance or line changeover. For procurement engineers managing aging FP2 installations or executing system upgrades, the AFP2720 is a critical spare and a direct OEM-compatible replacement.

- Rapid Program Transfer – Plug-and-play cassette swap enables sub-minute CPU program restoration during field maintenance
- OEM Direct Compatibility – Genuine Panasonic part; no firmware adaptation or compatibility risk with FP2 CPU units
- Long Service Life – Designed for industrial duty cycles; rated for thousands of write cycles with data integrity
- Compact Form Factor – Mounts directly inside CPU housing; no external wiring or mounting hardware required
- FPWIN Pro Integration – Fully supported by Panasonic’s current programming environment for seamless upload/download
System Architecture & Signal Flow
The AFP2720 integrates directly into the FP2 CPU’s internal memory cassette bay. Upon power-up, the FP2 CPU automatically detects and loads the program stored on the cassette into execution memory. The signal/data flow is as follows:
- Program Development → FPWIN Pro on engineering workstation
- Download → Via RS232C / USB programming port to FP2 CPU
- Storage → CPU writes program to AFP2720 cassette (non-volatile)
- Execution → On power cycle, CPU loads from cassette → executes scan cycle
- Backup / Transfer → Cassette removed → inserted into replacement CPU → instant program restore
This architecture is particularly valuable in multi-machine environments where standardized program versions must be maintained across identical production cells.

Technical FAQ
Q: Is the AFP2720 compatible with all FP2 CPU models?
A: The AFP2720 is designed for the FP2 Series platform. Compatibility depends on the specific CPU model and firmware version. Please confirm your CPU part number before ordering — our engineers will verify compatibility at no charge.
Q: Does the AFP2720 require any special tools for installation?
A: No. The cassette is a tool-free plug-in module. Power down the CPU, insert the cassette into the designated slot, and power up. The CPU auto-detects the cassette on boot.
Q: Can I use the AFP2720 to clone programs across multiple FP2 CPUs?
A: Yes. This is one of the primary use cases. Write the program to the cassette via FPWIN Pro, then physically transfer the cassette to each target CPU for rapid, identical program deployment.
Q: What is the write endurance of the memory cassette?
A: Flash/EEPROM memory in industrial cassettes is rated for a minimum of 100,000 write cycles under standard conditions, far exceeding typical PLC programming frequency.
Q: Do you provide a warranty?
A: Yes. We offer a 30-day DOA (Dead on Arrival) warranty. Extended warranty options are available for volume orders. Contact us for details.
Q: Can you supply multiple units or arrange blanket orders?
A: Yes. We support single-unit spot buys and multi-unit blanket purchase agreements. Volume pricing is available for orders of 5+ units.
