Practical Tips and Techniques
The productivity series of PLCs comes with 4 built-in communication ports for easy connectivity to your PC or various industrial networks. Ethernet protocols like Modbus TCP can be utilized with the RJ45 port on this PLC. Modbus TCP is an open (published) protocol that uses the Server (Master) / Client (Slave) architecture. It’s a very … Read more
Suppanel is an Android app that is used to create a human machine interface (HMI). This HMI panel can be created on your computer, tablet or phone using the appropriate operating system or software. You can use this software to create panels that you can control or modify values in your automated system. These panels … Read more
We will apply the five steps to PLC program development to a pick and place robot example. The example will use a BRX PLC communicating to Factory IO (3D Software Simulator). Developing the PLC program is a process that can be clearly defined. In our series on the five steps to PLC program development, we … Read more
We will look at a PLC programming example of delaying the start of 7 motors. Each motor will be on a switch that the operator can select at any time. The motor outputs should have a 5-second delay between the outputs coming on. This question originally came from PLCTalk.net. An original solution to the problem … Read more
PLC programs are typically written in a particular application on a personal computer, then downloaded to the PLC. This downloaded program is similar to compiled code to keep the program efficient. The program is stored in the PLC in battery-backed-up RAM or non-volatile flash memory. Five Different PLC Programming Languages Albert Einstein said, “The world … Read more
We will look at a PLC basic tutorial of a paint spraying station. Following the five steps to program development, this PLC programming example should fully explain the procedure for developing the PLC program logic. Ladder logic will be our PLC programming language. We will use the Do-more Designer software, which comes with a simulator. … Read more
