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 pro-
cessor 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
