Practical Tips and Techniques
We will demonstrate pallet management logic on the Do-More PLC Simulator and EasyPLC. EasyPLC software suite includes a machine simulator named Machine Simulator (MS). It has a variety of machines that can be programmed and customized. One of these machines is the pallet management machine, which utilizes four conveyor belts, three photocells, and two stops. … Read more
The Productivity 2000 series of PLCs has five 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
The Productivity 2000 series of PLCs has five built-in communication ports for easy connectivity to your PC or various industrial networks. Serial protocols like Modbus RTU can be utilized with the RS232 or RS485 ports on this PLC. Modbus RTU (Serial) is an open (published) protocol that uses the Master / Slave architecture. It’s a … 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 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
