Auxiliary Relays in PLC - Internal Relay or Memory Bits

In this video, we will learn about auxiliary relays in PLC programming. These are also called internal relays or memory bits. The internal memory bits are very useful during the designing of complex ladder logic programs. We can use these internal relays/memory bits in the output instructions and again use these statuses on the input side.
