Practical Tips and Techniques
We will now look at data conversion instructions in the Omron Cp1H Controller. Programmable logic controller programming is all about manipulating the bits within the memory of the controller. Sometimes we need to convert from one form to another. This is where we will use data conversion instructions. BCD to Binary, Line to Column, Grey … Read more
Programmable logic controllers are not typically known for their math ability. Modern PLC controllers now come with several math instructions to expand the ability to perform math routines. Every controller has different methods to handle math with different numbering systems. Binary, BCD (Binary Coded Decimal), and floating-point single and double are examples of some numbering … Read more
We will now look at data shifting instructions in the Omron CP1H controller. PLC programming is all about how we can manipulate the information stored in the PLC. We have already looked at timers, counters, moves, and comparison instructions. Data shifting is a different concept that will move bits and words around in memory. This … Read more
We will now look at the compare instructions available on the Omron CP1H controller. Just about every program usually has some data comparison instruction. This is the ability to compare information from one area of the controller to another and act on results. The Omron CP1H series of programmable logic controllers provide several different ways … Read more
Every program usually has some kind of data movement. This is the ability to transfer information from one area of the controller to another. The Omron CP1H series of programmable logic controllers provide several different ways to manipulate this information. We will be looking at several different ways in which data movement can happen with … Read more
The Omron CP1H series of programmable logic controllers are capable of having 4096 basic counters. There are two basic counter instructions in the PLC. Each of the basic instructions can be either binary or BCD. The memory area for counters has separate areas for the Counter PVs (Present values) and the Counter Completion Flags. We … Read more
