BRX Do-More PLC Using Modbus IO Scanner Profile


The Do-More Designer Programming Software (2.9) or higher includes a Modbus I/O Scanner with some profiles for Modbus Server (Slave) devices. This will greatly reduce the time it takes to implement and troubleshoot communications in your projects. Modbus communications are done independent of the PLC scan time and will have little or no ladder logic for the program.

Last time we communicated to a Solo process temperature controller via Modbus RTU RS485. (twisted pair) We manually set the Modbus IO scanner, reading the present value (PV) and set value (SV) of the Solo. The writing of the set value (SV) located within the BRX Do-More controller was also done. This was all be done without using any ladder logic code. We will now use the Modbus profile in the Modbus IO Scanner to connect a Click Plus PLC to our RS485 network. Using the Modbus scanner to write and read instructions we will also show how to use the ladder logic code with our scanner. Let’s get started. Continue Reading!

BRX Do-More Simple Modbus Serial Communication


The newest version of the Do-More Designer Programming Software (2.9) includes a Modbus I/O Scanner. This Modbus scanner will simplify Modbus RTU serial communications to any device. Communications are done independent of the PLC scan time and will have little or no ladder logic for the program.

We will be communicating to a Solo process temperature controller via Modbus RTU RS485. (twisted pair) Setting up the Modbus IO scanner and reading the present value (PV) and set value (SV) of the Solo. We will also write the set value (SV) located within the BRX Do-More controller. Communications will happen without using any ladder logic code. Let’s get started. Continue Reading!

BRX Do-More PLC High-Speed Input Timer


The High-Speed discrete inputs can be configured to measure the amount of time between pulses. When you want a scaled value representing a speed or rate, the high-speed input timer is a better option for pulse rates below 5 kHz. This is compared to using the high-speed input pulse counting selection.
BRX Do-More PLC High-Speed Input Timer
The BRX Do-More series of programmable logic controllers have built-in high-speed inputs. These inputs can function in Counter, Timer, or Pulse Catch modes. Every CPU will have either 6 or 10 high-speed inputs (HSI) available depending on the model. These inputs can be used for input frequencies from 0 to 250Khz. 250Khz represents 250000 input counts per second that can be coming from devices connected to your PLC like an encoder. Due to the speed of the inputs, they function on the BRX Do-More PLC asynchronous with the PLC scan time.
We will continue looking at the high-speed inputs on our BRX Do-More PLC, by looking at the pulse timer mode. Previously we looked at the high-speed count mode of the PLC. We scaled the count to display RPM (Revolutions per Minute). Scaling the edge trigger timer from our incremental encoder, we will scale and compare the RPM from last time. Let’s get started.

EasyPLC Paint Line Bit Shift – BRX Do-More PLC


The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that are used to show different programming techniques. The paint line is one of these machines. It will use a bit shift (shift register) to track bottles along a conveyor belt. All the bottles will be detected using photocells and tracked along the conveyor. Larger (taller) bottles will be painted and then pushed into a box at different sections of the conveyor belt. A control panel will be used to start and stop the paint line and display the bottle count. The paint line machine simulator is an excellent way to learn how to program shift registers (bit shift) in the PLC.
EasyPLC Paint Line Bit Shift - BRX Do-More PLC
The BRX Do-More PLC will be used to program this virtual paint line machine. Using the BRX Do-More PLC, we will connect to the paint line machine. This will be done using Modbus TCP (Ethernet) for communications. Using the five steps for program development we will show how this is programmed. Let’s get started. Keep on Reading!

Do-More Designer Element Browser


The element browser in the Do-More Designer software will display valid memory locations, add documentation, and show how to cast from one memory type to another.
Do-More Designer Element Browser
We will be discussing the element browser and how to take advantage of this in your Do-More program. Let’s get started. Continue Reading!

BRX Do-More PLC FTP Client Get Put


We will look at the BRX Do-More FTP (File Transfer Protocol) on our PLC. Using FTPGET and FTPPUT instructions we can transfer files to an FTP server. Our BRX Do-More PLC now has the ability to be an FTP Client. This will allow us to transfer our logged files to an FTP server that we programmed in the following post.
Data LoggingVideo
As an FTP Client, the Do-More PLC now has the ability to transfer and retrieve files from the network at an appropriate time in the PLC logic.
BRX Do-More PLC FTP Client Get Put Windows 10 FTP Server
We will be setting up a Windows 10 FTP server on our computer. Using the FTPPUT FTP Client command on our BRX Do-More PLC we will store a file on our FTP server. The FTPGET Client command instruction will be used to retrieve a recipe text file on our server. This recipe file will have three timers that we will be used in a sample program to turn on some outputs. Let’s get started. Continue Reading!
