Practical Tips and Techniques
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. We will … 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
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
The productivity suite programming software has a debug mode. This will allow you to view and control the rung execution on your ladder logic code. These programming tools allow you to troubleshoot, find, and correct errors in the PLC programming logic. We will be adding a couple of rungs to our exiting start-stop circuit we … Read more
