Practical Tips and Techniques
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
An array is a storage area for common data type tags. They usually have some relationship with each other and must be manipulated as a group. We can use arrays for motion control, recipe management, sequencing (indirect addressing), math, etc. The Productivity 2000 Series PLC uses arrays programmed using the Productivity Suite Software. Previously we … 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
We will connect two Click PLUS PLCs and communicate in three different ways. Using the send and receive commands, we will set up one PLC to be the master (client) and communicate with the slave (server). WiFi, Ethernet, and Serial communication will share common memory areas between the Click PLCs. The send and receive commands … Read more
Most programmable logic controller (PLC) programs will include a counter instruction. The Productivity 2000 Series PLC has two different counter instructions for your program. These can be used in several different ways to adapt to your application. Basically, counters are used to count up or down to a specific limit. When the limit is reached, … Read more
