4 MByte static SRAM (32 Bit RAM) and 2 MB Flash PROM are available.
ETCHC: The firmware has a memory requirement of 1 ... 1.5 MB SRAM and
1 MB Flash PROM. This means that the user has 2.5 ... 3 MB SRAM and 1 MB
Flash PROM available. This is sufficient for e.g. typically 128 NC sentences
(preprocessing buffer), 512 kB PLC program, 128 kB PLC data and 1 MB SPV
memory (DIN program memory).
ETCHM: The firmware has a memory requirement of 1 MB SRAM and 1 MB
Flash PROM. This means that the user has 3 MB SRAM and 1 MB Flash PROM
available. Verfügung. This is sufficient for e.g. typically 2000 kB PLC program
and 1000 kB PLC data.
The memory allocation can be configured by the user.
