Practical Tips and Techniques
There are four fundamental variable types in PLC programming: Boolean, Integer, Real, and String. This is a universal concept for all PLC programming but needs to be clarified due to the acronyms and various names used by manufacturers and PLC hardware. Your controller programming manual will help you understand the terms of the variables in … Read more
You’ve had this idea for years since you were a kid. You want to be an electrical engineer, and you’re finally going to follow through on it and learn PLC programming to start your career off right! What? That’s what you thought, anyway. But then you started googling around, trying to figure out how to … Read more
All programmable logic controllers (PLC) have the same numbering system at their core. This is the same with all computers as well. The status of any memory location can be either on or off. A one (1) will represent an on or “True” status and zero (0) will represent an off or “False” status. This … Read more
The data control instructions in the Omron CP1H programmable logic controller are used to manipulate the outputs based upon control conditions. Control is the main purpose of these instructions within the PLC. Instructions include PID (Proportional, Integral, and Derivative), PID with Autotuning, Dead Band Control, Limit, Dead Zone Control, Time Proportional Output, Scaling, etc. We … Read more
The Omron CP1H programmable logic controller has several different table data processing instructions. These instructions are used to handle table data, stacks and other ranges of data. We can define a stack of data. With this data we can then do the following: add new data by pushing onto the stack, use FIFO (First In … Read more
The Omron CP1H programmable logic controller has several different ways to control the program and the way in which your program executes. Sequence control, Subroutines, and Step instructions can be used. These are just a few ways in which the controller will execute your logic using a synchronous PLC scan. Understanding the PLC program scan … Read more
