In this second part, we will finally know which is the adequate contact for a stop button and why. If you have not read the part one, click here. Merging Software and Hardware Every boolean instruction in a PLC program has a specific address, which is of a single bit and it will be given …
Which contact should I use for a stop button? (Part II) Leer más »
Contacts and stop button In this post about contacts and a stop button, we are going to determine which contact is better to use for this type of button. In this part I, we will see the hardware logic and software logic. Hardware Logic First of all, we are going to talk about digital inputs …

Basic example of Counter contact with IECuino Here, we will see another example, but this time it is going to be about Counters. It means that this is Counters Example I. As the previous post, we are going to explain what Counter means, in case you forgot its function. As the name suggests, this contact count …
Basic example of Timer Contact with IECuino In this post, we are going to see a super basic example of Timers, which is the Timers Example I of this blog, but before we start to explain it…can you differentiate Counters and Timers? We are going to explain to you what Timer means so easily.As the …
It is a bit complicated to understand the PLC Wiring, Ladder Diagram symbol combinations and their logic states when one starts with PLCs and Ladder Logic. Therefore, we will be explaining in detail how to go about it. For ease of understanding, here you have an illustration: Referring to the image above, there are 3 …
Ladder Logic Basic Example In this post, you are going to see a Ladder Logic Interlocking example, specifically the PLC Diagram for Motor Interlocking. In this way, you can get to know the applications of this programming language. This example will consist of making an interlocking (self-retention) of a single-phase motor. To make it easier, …
In other posts, we have already briefly explained the Components of Ladder Logic, but in this post, we are going to go into detail about these Ladder Logic Components in IECuino. Specially, we will look at five components, which are the principal ones: Inputs Rung Comments Outputs Rails Tag Names Rungs 1. Inputs The Ladder …
In the top 5 most popular PLC programming languages, we found Ladder Logic. Before developing PLCs, manufacturing plants used relay-based circuitry to activate various loads depending on the Relay’s interconnection. The problem was that relays were expensive, needed continuous maintenance, and were difficult to modify. It was necessary to maintain the previous system’s similarities; hence, …
How Ladder Logic instructions work with the PLC scan cycle In this second part of the post “PLC scan cycle with LL”, we are going to talk about the Output Latch and the Normally Closed Contact. We recommend that you have read the first part of this post. Output Latch As we have explained previously, …
In this post, you will learn the Ladder Logic Basics, but… what does the Ladder Logic do? Ladder Logic automates monotonous machine sequences and tasks. For making logic expressions for a PLC, it is a practical and quick method. Some examples of the Ladder Logic Basics are: Hopper and Tank Level Control. Logistics Package Conveying …
