Practical Tips and Techniques
Automation Direct Productivity 1000 Series PLC. This is part of the productivity series featuring the 1000, 2000 and 3000.
Programming an input to debounce on and off can be done using logic control systems like Programmable Logic Controllers (PLCs). This process helps to ensure the accuracy of signals sent to and from PLCs and eliminates noise interference. Using the Productivity Suite PLC Programming software, we will demonstrate the ladder logic using the simulator. We … Read more
Programming a simple parking lot control is quickly done with the Productivity PLC Simulator. This comprehensive software suite is developed to simulate and control the PLC’s creation, management, and operation without the hardware. It accurately represents the complete PLC hardware from inputs, outputs, and logic control. The intuitive software enables you to understand, develop, debug, … Read more
Data handling instructions are used to perform movement and manipulations of the memory in the programmable logic controller. The Productivity 2000 Series PLC has fifteen different data handling instructions that can be used in various applications. This includes all of the data handling instructions. Understanding the full capability of the PLC that you are programming … Read more
There are four fundamental variable types in PLC programming: Boolean, Integer, Real, and String. This is a universal concept for all PLC programming but needs to be clarified due to the acronyms and various names used by manufacturers and PLC hardware. Your controller programming manual will help you understand the terms of the variables in … Read more
You’ve had this idea for years since you were a kid. You want to be an electrical engineer, and you’re finally going to follow through on it and learn PLC programming to start your career off right! What? That’s what you thought, anyway. But then you started googling around, trying to figure out how to … Read more
Timers are one of the first things you learn about programmable logic controllers. (PLC) Just about every PLC program will include timer instructions. The Productivity 2000 Series PLC has several different timer instructions for your program. We discussed the timed coil (TMC) and flasher coil (FLS) last time as part of the ladder logic output … Read more
The Productivity Suite Software comprises more than 82 instructions divided into 14 categories. These instructions include Out, Set, Reset, OR Out, Flasher, Debounce, Timed, Toggle, Program End, and No Operation. Coils (Outputs) are one of these categories of ladder logic instructions to program your productivity PLC controller. Ladder logic outputs or coils are in every … Read more
The Productivity Suite Software comprises more than 82 instructions divided into 14 categories. These instructions include NO / NC, NO Edge / NC Edge, and Compare. Contacts are one of these instructions to program your productivity PLC controller. Ladder logic contacts are in every PLC program. We will be looking at these instructions in the … Read more
The Productivity Suite Software allows us to use tags in the PLC. Tags are a method for assigning and referencing memory locations (numbering systems) within the programmable logic controller. They allow a more structured programming approach and are stored within a tag database. The tag database is stored in the memory of the Productivity Series … Read more
We will use an MQTT broker in Node-RED to communicate to the productivity PLC clients. MQTT stands for Message Queuing Telemetry Transport. This simple ‘publish and subscribe’ communication protocol does not take too many resources. Constrained devices with low bandwidth are ideal for MQTT. This protocol provides machine-to-machine (M2M) connectivity, perfect for the Internet of … Read more
