NOR Logic Diagram
FBD:
LADDER:
=
Not ( I01 or I02 or I03 )
Note: The input terminal is NOP which is equivalent to ‘‘Lo”;
The B output ON when all input terminals status are OFF;
XOR Logic Diagram
FBD:
LADDER:
=
I01 XOR I02
Note: The input terminal is NOP which is equivalent to ‘‘Lo”;
The B output ON when the input terminals status are different;
SR Logic Diagram
FBD:
→
LADDER:
=
Logic Table I01 I02 B001
0 0 holding
0 1 0
1 0 1
1 1 0
Note: The input terminal is NOP which is equivalent to ‘‘Lo”;
NOT Logic Diagram
FBD:
LADDER:
=
Not I01
Note: The input terminal is NOP which is equivalent to ‘‘Hi”;
