ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
We will now look at communication between the Productivity 2000 PLC (Modbus TCP Server) and Node-RED (Modbus TCP Client). Node-RED is a powerful, adaptable HMI/SCADA (Supervisory Control and Data Acquisition) development package that uses flow programming. Minimal coding is required; you can see the program flow visually. The best thing is that the software is … Read more
Using Modbus RTU (RS485), we will connect the XY-MD02 Temperature and Humidity Sensor to the Click PLC. The Click will be the Client (Master), and the Sensor will be the Server (Slave). This is an ideal sensor to place in a panel to ensure that the panel is within a working temperature and humidity range. … 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 Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines, like the palletizing machine, that show different programming techniques. The palletizing conveyor example is one of these machines, and we will use the Do-More Designer PLC programming software. This will demonstrate a sequencer example. In this case, a box … 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 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
