How Ladder Logic Program Scan Works

How Ladder Logic Program Scan Works

PLC programs scan cyclically. This means that it is repeated many times and in the same order. The primary sequence of a PLC scan is reading the inputs, executing the program, diagnostics, and communication, and updating the outputs. We will look at these scan items with particular attention to how the ladder logic program is … Read more

Timing Diagram NOT Just Used for a Timer

Logic circuits in a PLC ladder logic program are either on or off. The inputs change, which will affect the outputs. This can be expressed in a timing diagram. The timing diagram or chart will show you how the ladder logic program will respond to the changing states of the inputs and outputs. This visual … Read more

PLC Counter Programming – 3 Things to Know

PLC Counter Programming - 3 Things to Know

PLC ladder logic counters are used in just about every PLC program. They will indicate how many times something has happened within the controller logic. Counters then can be used to trigger other outputs or items in the PLC. You can find counter applications in a variety of things every day. We will discuss three … Read more
