For Java applications there is a dedicated 20 MB main memory available with V4.1 SP1
HF6 and higher.

The specifications relate to CompactFlash Cards with a capacity of 512 MB and 1 GB. If
the "Upgrade SIMOTION devices" function is used, the downgrade option requires CF cards
with double the memory requirement for "each switch position". The 300 MB persistent
memories can, therefore, only be achieved with the 1 GB CompactFlash Card.

With CompactFlash cards, SIMOTION versions up to and including V4.1 SP1 inc. hotfixes
support a memory address of max. 512 MB. The limitation applies whether the card is being
used by SIMOTION runtime functions or for some other purpose such as storing documents.
Once there is more than 512 MB of data on the CompactFlash Card, then the card is full as
far as Simotion runtime is concerned, i.e.:
● SIMOTION runtime cannot write any further data
● SIMOTION runtime cannot read data beyond the 512 MB range.
