Practical Tips and Techniques
Ethernet communication protocol. This is part of the Modbus.
This tutorial is for beginners who are just starting to program PLCs. Using the EasyPLC simple conveyor, we will move a box back and forth on the conveyor. We will learn to write the PLC ladder logic program for this operation. Using the five steps to PLC programming development, we will determine what must be … Read more
We will connect two Click PLUS PLCs and communicate in three different ways. Using the send and receive commands, we will set up one PLC to be the master (client) and communicate with the slave (server). WiFi, Ethernet, and Serial communication will share common memory areas between the Click PLCs. The send and receive commands … Read more
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 solder robot example is one of these machines. This will demonstrate a sequencer robot example. In this case, four rivets are welded using a robot. The logic will step through … Read more
Building a PLC program series will take you through developing and programming PLC logic. This six-part series was released almost seven years ago but is still relevant today. Each part will add and build upon the previous step. This series will look at different ways to solve the same machine logic. Using discrete inputs and … Read more
Previously we looked at the easy PLC machine editor design simulation. We created a mixing tank simulation using the EasyPLC machine editor. The tank included a control panel and operation indication. We will now use the Do-More designer programming software to program the ladder logic for this EasyPLC mixing tank application. The built-in simulator of … Read more
The EasyPLC palletizing robot will demonstrate sequencing and robot control using a PLC. This palletization process will fill a box container with six cans. A servo-controlled gantry robot using x and y is used to do this operation. The complete box will then travel along to another conveyor to an unloading area. A robot will … Read more
