Purpose

The SD memory card is used to back-up user data and store user programs or project source codes as well as to update the internal CPU firmware. The Processor Modules can be operated with and without SD memory card.

AC500/AC500-eCo Processor Modules are supplied without SD memory card. It therefore must be ordered separately.

The MC memory card can be read on a PC with a standard memory card reader. AC500 Processor Modules are equipped with an MC memory card reader.

For AC500-eCo Processor Modules the device must be equipped with a MC503 SD memory card adaptor MC503 - SD Memory Card Adaptor.

Note

The SD memory card has a write protect switch. In the position “LOCK”, the card can only be read.

Note

The use of memory cards other than the MC502 SD memory card is prohibited. ABB is not responsible nor liable for consequences resulting from use of unapproved memory cards.
