PLC programs scan cyclically. This means that it is repeated many times and in the same order. The primary sequence of a PLC scan is reading the inputs, executing the program, diagnostics, and communication, and updating the outputs. We will look at these scan items with particular attention to how the ladder logic program is … 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
