Do-More Designer software features a fully functional simulator that can be used for teaching PLC programming. This software is free of charge.

EasyPLC Simulator Robotic Cell 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 robotic cell example is one of these machines. This will demonstrate a sequencer example. In this case, an engine is lifted and placed onto a rack. The logic will step through various steps to perform the task.
EasyPLC Simulator Robotic Cell BRX Do-More PLC
We will be using a BRX Do-More PLC and the Do-More Designer programming software to program this EasyPLC machine simulator engine loader of the robotic cell. This will be done using Modbus TCP (Ethernet) for communications. The program will allow you to start, stop and jog the sequencer. Modifications of the EasyPLC Robotic Cell will include controls for this operation. Using the five steps for program development, we will show how this sequencer is programmed. Let’s get started.

BRX Do-More PLC High-Speed Input Pulse Catch


The High-Speed Input Pulse Catch will set an output that can be seen by the PLC ladder logic scan in response to an input pulse. Inputs that are too fast to reliably be seen by the ladder logic scan time will be seen.
BRX Do-More PLC High-Speed Input Pulse Catch
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 catch mode. The pulse catch mode will be set up using the Z phase of our incremental encoder. Pulses will be counted using the input directly in the ladder logic and using the pulse catch bit. Comparisons will be made between the two counts and an output will be turned on when different. 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.

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.

BRX Do-More PLC High-Speed Input Counter

BRX Do-More High Speed Input Counter
We will be looking at the wiring of an incremental encoder to our BRX Do-More PLC. The A, B, and Z phases will be connected. Using the high-speed input menus in the Do-More Designer programming software we will specify the counter mode of operation. We will also scale the input so we can determine the revolutions per minute (RPM) rate. This will be monitored on our data view window. Let’s get started with the BRX Do-More PLC High-Speed Input Counter. Continue Reading!

ACC Automation

In this Covid-19 world, we are continuing to adapt. Social distancing, mask-wearing, hygiene, etc are the way we currently live. Video conferencing with Zoom, Teams, and Google Meet are the norm in business today. Information is knowledge, and everyone more than ever wants to be able to see, control and summarize production data on a regular basis. Open intuitive technologies are available to communicate like never before. Industrial plant data is rapidly changing. Factory 4.0 benefits are being seen and everyone wants to take advantage. We are looking forward to the New Year and new possibilities for implementing your control solution.

Each year we like to take a few minutes and reflect on the past, current, and future of ACC Automation. You have helped us to build the site that you see today through questions, comments, and suggestions. Thank you. Keep on Reading!

Do-More PLC – EasyPLC Box Selection Program


The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that can be programmed. The box selection (camera management and distribution) is one of these machines. It will read barcodes from the boxes and send them to different exit ramps. The Do-More Designer PLC Simulator will be used to program this virtual machine.
