Practical Tips and Techniques
PLC ladder logic counters are used in just about every PLC program. They will indicate how many times something has happened within the controller logic. Counters then can be used to trigger other outputs or items in the PLC. You can find counter applications in a variety of things every day. We will discuss three … 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
