the rung at the point of the instruction.
In the following example when X1 is off, Y2 will energize. This is because the Not

NOTE: DirectSOFT Release 1.1i and later supports the use of the NOT instruction.
The above example rung is merely intended to show the visual representation of the
NOT instruction. The rung cannot be created or displayed in DirectSOFT versions
earlier than 1.1i.
The Positive Differential instruction is
typically known as a one shot. When the
input logic produces an off to on
transition, the output will energize for one
CPU scan.
