Memory Architecture and Non-Volatile Storage

The Schneider TSXMFPP224K uses Flash EPROM technology for permanent data retention. Specifically, NOR Flash architecture allows byte-level read access for fast program execution. In addition, this memory card requires no battery backup for data preservation. Moreover, the card retains stored programs for up to 10 years without power. Consequently, you can store critical application code safely without periodic battery changes.

Program and Data Storage Features

This memory extension card provides 224 kilobytes of total storage capacity. For instance, 128 kilobytes hold the user’s ladder logic and function blocks. In addition, 96 kilobytes store configuration constants, recipe data, and parameters. Furthermore, the 150 ns access time ensures fast program loading to the CPU. Thus, this card serves as reliable backup for production-critical PLC applications.

Write Protection and Installation

A mechanical slide switch on the card body enables write protection. Specifically, moving the switch to the lock position prevents accidental overwrites. In addition, the card fits into any standard PCMCIA Type I slot. Moreover, you do not need to open the PLC cabinet for installation. Therefore, the Schneider TSXMFPP224K suits field technicians and maintenance engineers perfectly.

Compatibility and Usage Guidelines

This memory card works with TSX Premium P57 series processors exclusively. For example, compatible models include P571, P572, P573, and P574 CPUs. In addition, you can transfer programs from a PC using a PCMCIA adapter. However, do not remove the card while the PLC writes data to it. Thus, always power down or disable writes before card extraction.
