No Comments on 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 method is an excellent way of understanding how the PLC ladder logic functions. We will discuss a timing diagram and how it is used for timers, counters, and ladder logic. This will help in understanding or troubleshooting your PLC programs. Let’s get started.

The EasyPLC machining center loading robots will demonstrate sequencing and robot control using a PLC. Two input lines feed blanks to the robot. The robot will alternate taking the blanks and putting them into the CNC (Computer Numerical Control) machine. The robot moves the piece to the finished conveyor when the part has been machined. A three-axis robot loader will pick up the part and place this in a storage box on the roller conveyor.
Using the five steps for PLC program development, we will discuss and show you how to program this EasyPLC machining center. This will involve all the ladder logic to load and unload using the robot simulator. This PLC simulator will show sequencing and drum instruction programming using timers and events. An Automation Direct BRX Do-More PLC is used for this application, but the general methods can be used for just about any PLC on the market. Let’s get started.

No Comments on 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 things you need to know when programming counters in the PLC. A sample program with a counter will be shown. This will have a 3D simulation with the PLC. Let’s get started.

A rock crusher (jaw crushers) is also known as “rock breakers” and is used to break up larger, more complex materials into more manageable pieces. The EasyPLC simulator rock crusher plant will show you how you can control this process through a programmable logic controller. We will be using Do-More technology to control this plant automation.
Using the five steps for PLC program development, we will discuss and show you how to program this rock crusher plant. An Automation Direct BRX Do-More PLC will be used for this application, but the general methods can be used for just about any PLC on the market. Let’s get started.

The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that are used to show different programming techniques. The robotic cell example is one of these machines. This will demonstrate a sequencer example. In this case, an engine is lifted and placed onto a rack. The logic will step through various steps to perform the task.
We will be using a BRX Do-More PLC and the Do-More Designer programming software to program this EasyPLC machine simulator engine loader of the robotic cell. This will be done using Modbus TCP (Ethernet) for communications. The program will allow you to start, stop and jog the sequencer. Modifications of the EasyPLC Robotic Cell will include controls for this operation. Using the five steps for program development, we will show how this sequencer is programmed. Let’s get started.

The Do-More Designer Programming Software (2.9) or higher includes a Modbus I/O Scanner with some profiles for Modbus Server (Slave) devices. This will greatly reduce the time it takes to implement and troubleshoot communications in your projects. Modbus communications are done independent of the PLC scan time and will have little or no ladder logic for the program.
Last time we communicated to a Solo process temperature controller via Modbus RTU RS485. (twisted pair) We manually set the Modbus IO scanner, reading the present value (PV) and set value (SV) of the Solo. The writing of the set value (SV) located within the BRX Do-More controller was also done. This was all be done without using any ladder logic code. We will now use the Modbus profile in the Modbus IO Scanner to connect a Click Plus PLC to our RS485 network. Using the Modbus scanner to write and read instructions we will also show how to use the ladder logic code with our scanner. Let’s get started.
