Insertion of the SD memory card
AC500 CPUs are supplied without an SD Memory Card. It therefore must be ordered separately. 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. AC500 CPUs can be operated with and without SD Memory Cards.
The CPU uses a standard file system, which allows the MC502 SD Memory card to be read with a
standard memory card reader.
ATTENTION
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.
ATTENTION
In operation, the plugged-in SD Memory Card withstands vibrations up to 1 g.
Without using an SD Memory Card, the CPU itself withstands vibrations up to
4 g.
