Practical Tips and Techniques
We will now look at monitoring and testing our BRX Do-More program in our controller. Our first program for the BRX Do-More PLC involved a start-stop jog circuit. We will now use the Do-More Designer Software to monitor, test, and modify this program. As a system integrator, this ability can prove very useful to you … Read more
We will now look at writing our first program for the BRX Do-More PLC. The Do-More Series allows us to write programs online or offline with the PLC controller. The series will also allow us to do online editing. We can change program information and download the new program between scans of our controller. As … Read more
We will now use Modbus RTU to connect a Click Master to a BRX Do-More Slave controller. Recently I was asked to demonstrate communication between a Click PLC and BRX Do-More PLC using Modbus RTU. Both PLCs are available from automation direct com. Modbus serial communication (Modbus RTU) is a standard protocol used in many … Read more
We will look at numbering systems in our BRX Do-More controller. This will include physical IO, casting, and indirect addressing. The BRX Do-More PLC like all of the PLCs in the Do-More Series use strong data typing. This means that there are fixed memory structures to work within your program. Errors will be displayed if … 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
