When a Proven PLC Hits Its Memory Ceiling
A production line runs smoothly on a Modicon Premium processor. Then a recipe change, a new HMI screen, or a small logic update pushes the application past its built-in memory. Replacing the entire controller is expensive and slow. The TSXMFPP128K solves this exact problem. It is a Flash EPROM memory module from Schneider Electric that adds 128 kB of application memory to compatible processors through Slot 0.
What the TSXMFPP128K Actually Does
This module belongs to the TSX Micro PLCs product line and the Modicon Premium Automation platform. Engineers use it as a memory extension for processors. You install it in Slot 0, and the processor gains 128 kB of Flash EPROM application memory. The module measures 3.0 x 9.5 x 5.31 cm and weighs only 0.044 kg, so it adds almost nothing to the panel footprint.
Key Parameters That Matter on the Floor
Memory Capacity and Type
The 128 kB Flash EPROM capacity directly determines how much application logic and data the processor can hold. Flash EPROM keeps stored content stable without a constant power supply.
Processor Compatibility
The module works with Modicon Premium Automation platform processors, including TSX570 to TSX574, TSX57C, and TSXPCI572/3. Confirm your exact processor reference before ordering.
Environmental Durability
The operating temperature range spans -25°C to +70°C. Storage tolerates -40°C to +85°C. The module resists shocks of 15 gn for 11 ms and vibrations of 3.5 mm from 10 to 55 Hz. Relative humidity from 5% to 95% non-condensing is acceptable, and operation is rated up to 2000 meters altitude.
Compliance
The module is RoHS compliant and carries Green Premium sustainability status.
Where This Module Earns Its Place
Packaging Line Recipe Expansion
A plant adds new product sizes to an existing Modicon Premium controller. The original memory fills up. Adding the TSXMFPP128K in Slot 0 provides the extra 128 kB needed for new recipes without a full controller swap.
Water Treatment Retrofit
Aging TSX Micro PLC installations often need small logic additions for new monitoring points. This memory extension keeps the existing architecture intact and avoids a costly migration project.
OEM Machine Support
Machine builders supporting installed Modicon Premium systems keep this module on hand. It restores memory capacity quickly when an end user requests a functional upgrade.
Installation and Setup Notes
Install the module in Slot 0 of a compatible processor. Follow Schneider Electric’s installation documentation for your specific processor model. Handle the module carefully during insertion. Verify that the processor recognizes the added memory before downloading the application. Do not force the module into any slot other than Slot 0.
Maintenance and Long-Term Reliability
The module has no moving parts, so wear is minimal. Inspect the installation periodically for secure seating and contamination. Keep the cabinet within the stated operating temperature range of -25°C to +70°C. Avoid condensing humidity above 95%. In rugged environments, confirm that shock and vibration stay within the rated limits of 15 gn for 11 ms and 3.5 mm from 10 to 55 Hz.
Compatibility and Integration
This module integrates with the Modicon Premium Automation platform. Supported processors include TSX570 to TSX574, TSX57C, and TSXPCI572/3. It also serves the TSX Micro PLCs product line. Check your processor reference and firmware level before purchase.
What to Verify Before You Buy
- Confirm your processor model appears in the compatibility list.
- Confirm you need 128 kB of additional application memory.
- Confirm Slot 0 is free on your processor.
- Confirm your cabinet environment stays within the stated temperature, humidity, altitude, shock, and vibration limits.
