The ABB 1SAP180100R0001 is the ordering number for the MC502 SD Memory Card, a removable storage accessory used with compatible ABB AC500 PLC configurations. In an automation system, the memory card provides storage for supported controller functions, including specific firmware-update and maintenance procedures.
For a maintenance engineer working on an existing AC500-eCo V2 controller, the MC502 can be relevant when preparing a memory card for an approved firmware-update procedure or other supported storage operation. The card is a separate component from the MC503 memory-card adapter, which provides the required interface for compatible PM55x-xP and PM56x-xP processors.
The MC502 is identified as a 2 GB SD memory card in the associated AC500 accessory documentation. Its use depends on the processor generation and the particular application. It should not be assumed that every AC500-eCo processor accepts the same card type or supports every storage function.
When replacing a card in an installed controller, engineers should check the CPU model, firmware requirements, and intended use before transferring files or inserting the card. A memory card prepared for one controller task may not automatically be suitable for another. During operation, the card should not be removed while the controller is accessing it, as doing so can corrupt stored files or interrupt normal PLC operation.

The MC502 stores digital files in solid-state flash memory. When installed in a compatible PLC memory-card interface, the controller can access the stored content for the functions supported by its hardware and firmware.
A typical arrangement for a compatible AC500-eCo V2 processor is:
MC502 SD Memory Card → MC503 Adapter, Where Required → Compatible PLC Processor
For example, a technician carrying out an approved firmware-update procedure may prepare the MC502 card with the required files, install it in the supported processor configuration, and follow the prescribed startup or update sequence. The processor then reads the card according to the update procedure.
The card itself does not execute PLC logic, control motor outputs, or provide communication interfaces. Those functions remain with the processor and the connected automation hardware. The MC502 supplies the storage medium used by supported controller operations.
Correct file preparation and compatibility are essential. An incorrectly prepared card, an unsupported storage format, or files intended for another processor may prevent the operation from completing. During normal operation, the memory card should only be removed when the controller’s instructions indicate that access has stopped and removal is permitted.
The MC502 serves as a removable storage component within supported ABB AC500 configurations. It complements the processor’s onboard memory rather than replacing the CPU or its application execution functions.

No. The MC502 is the memory card, while the MC503 is the memory-card adapter used with compatible processor configurations that require it. They perform different functions and have separate ordering numbers.
It can be used for supported firmware-update procedures when the target processor accepts the card and the required files are prepared according to the applicable instructions. The procedure varies by processor and firmware version.
No universal compatibility should be assumed. Check the exact processor generation and the documented memory-card requirements before selecting the MC502.
Do not remove the card while the controller is accessing it. Follow the processor’s status-indicator and removal instructions to avoid corrupting files or interrupting PLC operation.
