Load-memory role

The removable card supplies the stored user program to a supported CPU.

Safe program changes

A full program download replaces the previous card contents.

Substitutio Controlata

In IM151 CPU service, protect active writes and use the card ejector before removal.

Product Overview

6ES7953-8LF00-0AA0 is the 64 KB, 3.3 V NFLASH Micro Memory Card listed for supported S7-300, C7 and ET 200S IM151 CPU applications.

The card acts as nonvolatile load memory and a portable storage medium, so correct project content, available capacity and controlled replacement are central to maintaining the installed CPU application.

Focus ordinandi: Preserve the exact LF00 article and the correct machine project, and distinguish a CPU memory reset from a card-formatting operation before service.

Key Functions

Supply program content to work memory

In the IM151-7 CPU, a normal memory reset reloads the sequence-related program content from the card into CPU work memory.

Replace the complete stored application

Downloading an entire user program through the supported CPU workflow deletes the previous card contents before loading the new program.

Support controlled machine service

The IM151 CPU card receptacle uses an ejector, and the beveled card edge provides an orientation reference for insertion.

Quaestiones Frequenter Rogatae

Num normalis IM151-7 CPU memoriae reinitiatio applicationem in 6ES7953-8LF00-0AA0 delere potest?

Normalis memoriae reinitiatio programmatum sequentiam-relatam a schedula in memoriam operativam recarrit, dum integrae schedulae contenta retinentur.

Quid fit ad vetus projectum cum integrum novum programmam ad 6ES7953-8LF00-0AA0 transfero?

Integra usoris-programmatis translatio praecedentia schedulae contenta ante novam applicationem immittendam delet.

Quae inspectiones sunt necessariae antequam 6ES7953-8LF00-0AA0 e IM151-7 CPU removetur?

CPU in statum STOP pone et certifica ne quaevis PG scripturae functio activa sit; si hoc non garantiri potest, connexionem communicationis interrumpere.

Quomodo 6ES7953-8LF00-0AA0 in IM151-7 CPU receptaculum inserendum est?

Oram obliquam versus expulsorem dirigere et schedulam leniter in receptaculum premere donec haereat.

Cur 6ES7953-8LF00-0AA0 mutatio post alimentationis initium automaticam memoriae reinitiationem inducere potest?

IM151-7 CPU detegit cardem substitutam aut contentum cardis mutatum et post activationem automaticam memoriam reinitiat.

Num possum integrum projectum STEP 7 in 6ES7953-8LF00-0AA0 servare ad ulteriorem recuperationem?

Functio salutis projecti supportata datam projecti compressam in cardem immittit, dum spatium sufficiens ad programmatum utentis et archivum manet.

Cur oportet me projectum machinae inspicere antequam 6ES7953-8LF00-0AA0 in alium CPU inseram?

Cardo insertus debet continere rectum programmatum utentis pro machina destinata, quia CPU suum programmam ex hoc medio onerat.

Compatibility & Ordering Notes

Antequam 6ES7953-8LF00-0AA0 ordinatur: Identifica cardem LF00 requiritam et conserva copiam verificatam projecti machinae intenti, cum spatio libero sufficiente pro programma onerando et quibusvis datis technicis archivandis.

Index Compatibilitatis pro 6ES7953-8LF00-0AA0

• Index accessoriorum C7-635 identificat cardem LF00 64 KB pro usu S7-300, C7 et IM151 ET 200S supportato.
• Assure that the target CPU’s load-memory requirement and additional archive size fit within 64 KB.
• In IM151-7 CPU service, use STOP and prevent PG writes before removal; do not interrupt an active write operation.
• Insert the card using the beveled-edge orientation and the receptacle ejector arrangement.
• Keep normal CPU memory reset separate from formatting, which is used only when the card content or format requires recovery.
