The CPU has an integrated power supply. The power supply has to be provided with DC
24V. Via the power supply not only the internal electronic of the CPU is provided with
voltage, but also the electronic from the integrated IO modules and the sensor output.
The power supply is protected against polarity inversion and over current.
3.2.3 Memory management
The CPU has an integrated memory. Information about the capacity of the memory may
be found at the front of the CPU. The memory is divided into the following parts:
n
Load memory 128kbyte
n
Code memory (50% of the work memory)
n
Data memory (50% of the work memory)
n
Work memory 64kbyte
–
There is the possibility to extend the work memory to its maximum capacity
128kbyte by means of a VSC.
3.2.4 Slot for storage media

3.2.5 Buffering mechanisms
The SLIO CPU has a capacitor-based mechanism to buffer the internal clock in case of
power failure for max. 30 days. With PowerOFF the content of the RAM is automatically
stored in the Flash (NVRAM).
