Properties of the safety PLC
The 32-bit RISC-CPU 667 MHz of the standard PLC is used jointly with the BMC-M-SAF-
02 for safety programming.
A 32-bit RISC-CPU with 400 MHz is also used.
m
Program memory of 1 MB for the executable program code of the safety application
which has been created with ProSafety.
m
With the dual-channel solution, the IEC program code is translated via the ProSafety
programming user interface with two different compilers; the output of compiler 1 is ex-
ecuted on channel 1, while the output of compiler 2 is executed on channel 2 (1 MB of
executable program code each).
m
IEC data memory (SDRAM) 256 KB
Programming interface via system components ethernet connection.
m
Safety PLC file system Flash 6 MB in total, of which:
n
1 MB of program memory per channel,
n
100 KB of configuration data,
n
750 KB of configuration data stacks,
n
2 MB reloadable stack area
