Memory Technology

The Schneider ASP371002 uses EEPROM technology for non-volatile program storage. It retains all data for up to 10 years without any external battery. Unlike RAM modules, this unit does not lose programs when power fails. Consequently, you do not need backup batteries or frequent program reloads.

Capacity and Program Storage

This module holds 32 KB of user ladder logic and configuration data. A typical TSX 37 program occupies between 8 and 24 KB of memory. Therefore, this module accommodates most mid-size control applications comfortably. You can also store comments and symbol names along with the ladder code.

Installation and Removal

Insert this module into the programming port on the front of a TSX 37 CPU. The 14-pin male header mates with a dedicated female connector on the processor. You do not need any tools for installation or removal of the module. For best results, power down the PLC before inserting or removing the pack.

Program Transfer and Operation

The PLC loads the program from this module automatically at power-up. You can also initiate a transfer using the programming software manually. The module writes data to the CPU at approximately 4 KB per second. Therefore, a full 32 KB program transfers in about 8 seconds.

Duplication and Backup

You can copy programs from one memory pack to another using a programmer. This feature allows you to create duplicate modules for multiple machines. You can also keep a spare memory pack for emergency replacements. Consequently, downtime reduces significantly when a CPU requires replacement.

Write Protection and Security

A physical write-protect switch prevents accidental overwriting of stored programs. You can also set software protection levels using the PLC configuration. The label area allows you to write program names and revision numbers clearly. Therefore, technicians can identify the correct program pack at a glance.

Why Choose This Memory Module

This original Schneider module guarantees compatibility with TSX 37 CPUs. Generic memory packs may cause program corruption or boot failures. Therefore, choose this genuine part for reliable program storage and transfer.
