Practical Tips and Techniques
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
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. It is important to look at the capabilities of your programmable logic controller. This will lead you to different … Read more
Math instructions perform mathematical calculations. The Productivity 2000 Series PLC has math instructions that you can use in various applications. We will look at the Data Statistics (DATA) and the Math Editor (MATH). We will demonstrate both of these instructions using the examples in the help file. An average wind speed will be calculated using … 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
The Productivity Suite Software allows us to modify our existing program and execute the new code without stopping the scanning of the PLC. This is referred to as online programming or editing. We change the ladder logic code and when we save it to the PLC, the current scan of the PLC is held until … Read more
The Productivity Series 2000 and 3000 CPUs and remote controllers have OLED/LCD displays. The data can be system errors and information or user-defined messages programmed through ladder logic. Operators, maintenance, or programmer can use this information for running conditions, troubleshooting, or other items for the PLC system. We will be looking at the CPU OLED/LCD … Read more
