The C-More Micro HMI panel is a series of human-machine interfaces (HMI) that provide a way for the operator to control and view your programmable logic controller. (PLC) The free C-more microprogramming software is user friendly and fully featured. C-more Micro panels can easily display text, graphics, and bitmaps to effectively communicate critical data to your operator.
We will connect the EA3-T4CL cmore micro HMI screen to the Omron CP1H PLC. The devices will communicate serially via an RS485 interface. We will demonstrate reading and writing bits and words from the HMI unit. Let’s get started. Continue Reading!
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 is free. We will look at using AdvancedHMI with the Omron CP1H PLC.
Our sample CP1H PLC program will use buttons and indicators to control a start/stop jog circuit. An analog input into the PLC will be scaled and displayed on a gauge on our AdvancedHMI screen. We will also write information to our 7 segment display on the CPU from our AdvancedHMI screen. This communication will be done using Omron serial host link protocol over an RS485 serial cable. The AdvancedHMI package will run on a windows PC and communicate out the port using a USB to RS485 adapter. Let’s get started. Continue Reading!
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 will be looking at some of these instructions in the Omron CP1H PLC. Examples of the instructions will be presented. Continue Reading!
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 First Out), use LIFO (Last In First Out), find the current stack size and read, overwrite, insert or delete from the stack.
Dimension record tables are used to define the length of each record and the number of records. We can then write and read these records. This is ideal for data acquisition projects.
Other instructions found in the table data processing instructions include searching, summing and finding minimum and maximum values.
We will be looking at these instructions in the Omron CP1H PLC. Examples of the instructions will be presented. Continue Reading!
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 will explain the synchronous and asynchronous program scanning.
Interlocks, Jumps, For Next Loops, Subroutines and Step instructions are some of the ways in which we can control our program in the PLC. We will be looking at some of these instructions in the Omron CP1H PLC. Examples of some of the instructions will be presented. Continue Reading!
