Practical Tips and Techniques
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
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. It is important to look at the capabilities of your programmable logic controller. This will lead you to different … 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 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
