ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
We will now use AdvancedHMI to communicate to our Omron CP1H controller. Advanced HMI is a powerful, adaptable HMI/SCADA (Supervisory Control and Data Acquisition) development package that takes advantage of Visual Studio. There is no coding required and you can simply drag and drop items onto the page. The best thing is that the software … 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 SOLO Temperature Controller is a single loop dual output process temperature controller that can control both heating and cooling simultaneously. It is available in 1/32, 1/16, 1/8, and 1/4 DIN panel sizes and is UL, CUL and CE approved. The name of the temperature controller is deceiving. This unit will also accept voltage and … 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
Previously we used VB6 (Visual Basic 6) to implement the Omron Host Link Protocol to communicate to our programmable logic controller. (PLC) In part 2 we used Visual Basic for Applications (VBA) to accomplish our host link serial communication. We will now look at using VB.Net to establish and retrieve information in and out of … Read more
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
PLC Beginner’s Guide to PLC Programming There are many different PLC manufacturers with other hardware and software. All of the programmable logic controllers have similar basic features. Here is how I would approach learning about basic PLCs. What is a PLC? (Programmable Logic Controller) – Video Top 7 problems with beginners using ladder logic – … Read more
