Non-volatile elements 
Description 
Non-volatile elements behave like signal conditioning. However, these output signals are 
retained after a power supply failure. 
If an input signal is pending, the non-volatile element issues an output signal according to 
the selected type:  
●  Non-inverting 
●  Inverting 
●  Edge rising with memory 
●  Edge falling with memory 
You can set the output response. 
The non-volatile element consists of 
●  two plugs (input and reset) 
●  one logic component 
●  one socket 
The following are available: 
●  two non-volatile elements (1 to 2) for the SIMOCODE pro C and SIMOCODE pro S basic 
units 
●  four non-volatile elements 1 to 4 for the SIMOCODE pro V basic units 
The following schematic shows the "Non-volatile element" logic modules:

always 0 if a reset is pending.
