III. Core Hardware Specifications

1. List of Compatible Devices
2. PLC Controllers

Full range of S7-1200 CPUs (1211C/1212C/1214C/1215C/1217C)

Full range of standard S7-1500 CPUs (1511/1513/1515/1516/1517/1518)

ET200SP Open Controllers

2. SINAMICS Drives

G120, G120C, V90, S110, S120 servos and inverters, used for storing drive parameters, firmware and fault logs

1. Six Core Functions
2. Permanent Program Storage Medium

S7-1200/1500 CPUs have no built-in storage. An SMC card must be inserted to permanently save user programs, hardware configurations, DB blocks, recipes and technology packages; programs will not be lost after power failure.

2. Medium for CPU Firmware Upgrade

Store firmware files on the card and insert it into the CPU. The firmware update will run automatically upon power-on without online PC connection.

3. Device Cloning & Rapid Spare Part Replacement

The card fully replicates programs and hardware configurations. When a PLC malfunctions, simply replace the CPU and insert the card for immediate operation, eliminating repeated program downloading.

4. Process Data Logging

The CPU can write production data, alarms and fault records to the memory card for traceability and production line data analysis.

5. Drive Parameter Backup & Actualizare firmware

Dedicated backup card for SINAMICS drives, supporting batch copying of inverter parameters and unified drive firmware upgrades.

6. PLC Secure Reset & Formatting

TIA Portal supports card formatting, program clearing and protection password setting to securely erase data before equipment delivery.

1. Scenarii de aplicare
2. Mic & Medium-Sized Standalone Automation

Standard S7-1200 applications for assembly lines, mașini de ambalare, masini-unelte, injection molding machines and conveyor lines with simple logic programs, where 4MB capacity is fully sufficient.

2. Standalone Servo & Inverter Control

Parameter backup and batch commissioning for single S120/V90 servo drives and G120 inverters.

3. After-Sales Spare Part Maintenance for Equipment

Spare program cards for production lines to enable fast replacement during equipment breakdowns and reduce downtime.

4. Simplified Production Line Data Traceability

Small-scale data recording without external SD expansion boards; fault and output data can be stored locally directly.

5. Mass Standardized Equipment Delivery

Pre-programmed memory cards for identical equipment models, ready for use once inserted and powered on at factory shipment.

VII. Capacity Selection Comparison (954 Series Memory Cards)

VIII. Precauții de funcționare (Mandatory Restrictions)

1. Mixing with ordinary SD cards is strictly prohibited: Ordinary SD cards lack Siemens encrypted partitions and cannot be recognized by PLCs, and may even damage the CPU card slot.
2. Risk of hot swapping: Removing the card while the PLC is running will cause immediate shutdown and program loss; power off the device before plugging or unplugging the card.
3. Formatting only via TIA Portal: Direct formatting on Windows PCs will destroy industrial partitions and render the card permanently unusable.
4. Erase-write cycle limitation: 4MB cards are not recommended for scenarios with frequent cyclic log writing; upgrade to higher-capacity cards to reduce wear.
5. Version compatibility: The old 02 version is compatible with all S7-1200/1500 devices, but the improved 03 versiune (6ES7954-8LC03-0AA0) is recommended for CPUs with new firmware.
6. Depanarea defecțiunilor comune

Full Compatibility Specification for 6ES7954-8LC02-0AA0 (4MB SMC Memory Card)

1. Controlere compatibile (PLC-uri)
2. Full S7-1200 Series (100% Complet compatibil)

Modele: 1211C, 1212C, 1214C, 1215C, 1217C. Compatible with all firmware versions with no version threshold restrictions.

Aplicații: Program loading, recipe storage, alarm logging, CPU firmware upgrade, device cloning

Prescripţie: The 4MB capacity is relatively small and cannot store large-size CPU firmware packages (12MB or larger cards are recommended for CPU firmware upgrades)

2. Full Standard & Safety S7-1500 CPUs (Complet compatibil)

Modele: 1511/1513/1515/1516/1517/1518, 1500F safety CPUs, 1500T motion CPUs. Recognizable with any firmware version V1.0 ~ V4.x.

> Nota: The new-generation G2 series memory cards (8LC04/8LF04) cannot be used with S7-1200, while this legacy 8LC02 card supports mutual interchange between S7-1200 and S7-1500.

3. ET200SP Open Controllers

ET200SP CPU OC series, supporting program storage, firmware update and parameter backup.

Incompatible PLC Series

S7-200SMART, S7-300/400, S7-1500 G2 CPUs dedicated to new-generation cards, ET200S/ET200pro controllers (no SMC card slot equipped)

1. Compatible SINAMICS Drives (Inverters & Servos)

This card can serve as a parameter backup and firmware upgrade medium for all models below:

1. Seria G: G120, G120C, G120P, G130, G150, G180
2. Seria S: S110, S120, DCM DC Converters
3. V Series: V90 PN Servos
4. S200 Servos: Usable for old firmware versions; 03/04 version cards are preferred for new S200 firmware

> Prescripţie: Complete drive firmware packages are generally larger than 4MB. This card is only suitable for parameter backup, not recommended for drive firmware upgrades.

III. Software (TIA Portal) Compatibilitate

Minimum supported version: TIA Portal V13 Basic/Professional

Maximum supported version: TIA Portal V18 (8LC03/04 replacement cards are recommended for TIA Portal V19 and above)

Key Reminder: Formatting and read-write operations must be performed via TIA Portal only; direct formatting via Windows card readers will damage the card irreparably.

1. Cross-Version Interchange Compatibility of the Same Series Memory Cards
2. 8LC02 (This Model) ↔ 8LC03 (New Replacement Model)

Fully hardware-compatible with identical pin definitions for direct interchange, and programs are universally applicable. 8LC02 has been officially discontinued, with 8LC03 as the standard replacement spare part.

2. 8LC02 ↔ High-Capacity Cards (8LE/8LF/8LL)

Physically interchangeable; projects stored on the cards can be copied mutually with only capacity differences. Projects written on small-capacity cards can be downloaded to large-capacity cards, while large projects cannot be written to 4MB cards (storage shortage error will occur).

3. 8LC02 Cannot Replace G2 Series (8xx04) Cards: G2 cards adopt upgraded hardware architecture, and legacy cards cannot be recognized by G2-exclusive CPUs and drives.
4. Physical Hardware Compatibility
5. Card Slot: Standard industrial Micro SD slot shared by S7-1200/1500, ET200SP and all SINAMICS products, plug-and-play without adapters.
6. Alimentare electrică: 3.3V industrial Flash with unified power supply standard for all compatible controllers.
7. Compatibilitate cu mediu: Operating temperature range of -25℃~+70℃ matches all supporting equipment.
8. Capacitate & Functional Compatibility Restrictions (Key for Model Selection)
9. ✅ Supported Functions: Small logic programs, simple recipes, limited alarm logs, equipment parameter backup, CPU password clearing, device cloning
10. ❌ Unsupported Functions:

Large-size CPU firmware upgrades (firmware files are generally over 4MB)

Continuous high-frequency trend data logging, multiple technology packages, WinCC Runtime Advanced

Complete drive firmware upgrades (drive firmware far exceeds 4MB)

For the above scenarios, replace with models of 12MB or larger (6ES7954-8LE03-0AA0).

VII. Boundary Conditions for Common Compatibility Faults

1. S7-1500 with high firmware V4.x: The CPU can recognize 8LC02, but storage shortage alerts will pop up when downloading large projects.
2. Opening projects stored on 8LC02 cards via new TIA Portal V19: Read-write operations are available, yet official recommendations favor the new 03/04 version cards.
3. Ordinary consumer-grade SD cards: Fully incompatible, unrecognizable by PLCs and may damage card slots.
4. Hot swapping: Not a compatibility issue, but may cause program loss and CPU alarms.

VIII. Concise Summary (Quick Reference for Bidding & Selectarea modelului)

1. Compatibilitate PLC: Full S7-1200, S7-1500 and ET200SP Open Controller series; incompatible with S7-200SMART/S7-300/S7-400.
2. Compatibilitate cu unitatea: Full SINAMICS G/S/V90/S120 series (only for parameter backup, not suitable for firmware upgrades).
3. Software: Compatible with TIA Portal V13 ~ V18; 8LC03 new cards are preferred for V19.
4. Interschimbabilitatea: Direct replacement with 8LC03; cannot be interchanged with G2 04 series cards.
5. Capacity Shortcoming: 4MB only fits small-scale projects; capacity upgrade is required for multi-axis control, mass data logging or firmware upgrades.
