3.1.5 NOR
I1 I2 I3
Only when all the input of NOR function blocks are at a low potential (status 0),
the output will be closed (status 1). If any input is at high potential (status 1),
the output will be open (status 0).
Logical frame of “NOR”:

The electrical line diagram for parallel
connection of a certain number of NC
contacts is shown as follows:
The symbol of NOR in FAB2 is
shown as follows:
As shown in the line diagram, In FAB2,
the two commutator contacts for XOR
are connected in serial as follows:
In FAB2, the symbol of XOR is
shown as follows:
