1) As of firmware 2.5.x
2) Temporary use of MC5102 is possible under normal environmental conditions, but MC5141 should be preferred.
The use of other memory cards is prohibited. ABB is not responsible nor liable for consequences resulting from use of unapproved memory cards.
Purpose
Processor modules can be operated with and without (micro) memory card.
Processor modules are supplied without (micro) memory card. It must be ordered separately.
The memory card is used to store or backup application data and/or application programs or project source codes as well as to update the internal CPU firmware.
The memory card is intended for long-term use in standard and XC application.
The memory card can be read/written on a PC with a SDHC compatible memory card reader.
Dimensions
The dimensions are in mm and in brackets in inch.
Insert the memory card
-
Unpack the memory card.
-
Insert the memory card into the memory card slot of the processor module until locked.

It is not possible to use 100 % of a device's memory space. About 10 % of the total available space must remain unused at any time to maintain normal device operation.
The specified values represent the frequency with which memory blocks can be written or erased. However, they do not reflect the user's ability to write or erase these blocks. It should be noted that the internal controller may perform certain operations, such as internal management or error correction actions, which may also affect the total number of write/erase cycles.
Temperature is also a critical factor in memory card life. Therefore, it is imperative that the specified limits are not exceeded. In the case of the PLC, the sequential and non-random way of writing data helps to extend the life of the memory cells. And if the memory card is not used to capacity all the time, this can extend the overall life.
