Examples: LOD (Load), OUT (Output), and NOT
SET and RST (Reset)
The SET and RST (reset) instructions are used to set (on) or reset (off) outputs, internal relays, and shift register bits. The
same output can be set and reset many times within a program. SET and RST instructions operate in every scan while the
input is on.
