3.1.3 OR
Parallel connection of a certain number of In SR, the symbol of OR
NC contacts is shown in the SR line is as shown in follows:
diagram as follows:
I1
I2
I3
I4
This function block is called as OR, because the status for at least one of the inputs I1,
I2, I3 or I4 is 1 (i.e. closed), then output Q is 1.
Logic frame of OR:

3.1.4 NOT
The phase inverter is indicated in The symbol of NOT is as shown
SR line diagram as follows: in follows:
This function block is called as NOT, because if the input status is 0, then output Q is
1, and vice versa. In other words, NOT is the phase inverter for the input point.
Logic frame of NOT:
I1 Q
