Practical Tips and Techniques
The productivity series of PLCs has a built-in web server. This web server function can make a non-secure (HTTP) connection to the CPU. This is done with your browser. You can view read-only system tags and open, save, or delete files stored on the micro SD drive. Previously we stored data-logged files on the USB … Read more
In this tutorial, you will learn how to program a chain conveyor transfer using Do-More. The EasyPLC software suite includes a Machine Simulator (MS) with pre-programmed machines, including the chain conveyor. This machine can move boxes of various sizes along the production line, transferring them to different locations. We will use the Do-More Designer PLC … Read more
The productivity series of PLCs has a built-in data logger. This accessible data logger will log up to 64 tag values on a USB (Micro SD) storage device connected to the CPU. The logs will be stored in CSV (Comma Separated Values) file format. Logging can be triggered by the rising edge transition of a … Read more
The EasyPLC Software Suite is a comprehensive package with PLC, HMI, and Machine Simulator software. It features a Machine Simulator (MS) that allows virtual communication with many programmable logic controllers (PLCs) in a 3D world with real-time graphics and physical properties. Our PLC programming example will follow the five steps to PLC program development. We … Read more
The PLC productivity series includes a Drum and Sequencer instruction that can be very useful. The Drum instructions function similarly to an electromagnetically-operated drum sequencer. To better understand this concept, consider the mechanics of a music box. A small drum with pegs catches and flicks the chimes in a specific sequence to produce a tune. … Read more
The program control method and instructions will allow us to specify what parts of the logic get solved and when this happens. This will control how the PLC will scan and solve your logic in your program using a synchronous PLC Scan. Understanding the PLC program scan post will explain synchronous and asynchronous program scanning. … Read more
