BRX Do-More PLC Drum Instruction Sequence

We will now look at the drum instruction in our BRX Do-More Controller. Drum instructions are great tools when you have a simple sequence of events that need to occur at a set time interval or as a result of an event. They mimic an electromagnetic drum sequencer. The BRX Do-More Series PLC has a drum in the instruction set. Have you ever seen the mechanisms of a music box? Ok, so it’s a little drum with pegs that catch and flick the chimes in a particular sequence to play whatever tune is on the drum. So in the PLC, you can have a drum driven by an event, (input from a limit switch or button), or by time. We will discuss the drum instruction and look at an example of controlling traffic lights with a crosswalk signal. More information can be obtained at our website. This includes all of the links mentioned in this video. https://accautomation.ca/brx-plc-drum-instruction Previously in this BRX Do-More Series PLC, we looked at the following: System Hardware https://accautomation.ca/brx-plc-system-hardware System Hardware Video https://youtu.be/wSYgY09VYeA Unboxing Video https://youtu.be/-Tf8m3BqzPo Installing the Software https://accautomation.ca/brx-plc-installing-the-software Installing the Software Video https://youtu.be/iFI1ebP8Zkk Establishing Communication https://accautomation.ca/brx-plc-establishing-communication Establishing Communication Video https://youtu.be/shU5g8MA8VM Updating Firmware Video https://youtu.be/gsfcGGK4-Sk Numbering Systems and Addressing https://accautomation.ca/brx-plc-numbering-systems-and-addressing Numbering Systems and Addressing Video https://youtu.be/-GiKnIDycKY First Program https://accautomation.ca/brx-plc-first-program First Program Video https://youtu.be/ANSNhdlm_Ao Monitoring and Testing the Program https://accautomation.ca/brx-plc-monitoring-and-testing-the-program Monitoring and Testing the Program Video https://youtu.be/gv3d0vozxac Online Editing and Debug Mode https://accautomation.ca/brx-plc-online-editing-and-debug-mode Online Editing and Debug Mode Video https://youtu.be/77pemu3zXrE Timers https://accautomation.ca/brx-plc-timers Timers Video https://youtu.be/0qU9kgunPi4 Counters https://accautomation.ca/brx-plc-counters Counters Video https://youtu.be/k84VQy8ifgg High-Speed IO https://accautomation.ca/brx-plc-high-speed-io High-Speed IO Video https://youtu.be/6B5hp_Ri0Ls BRX PLC Compare Instructions https://accautomation.ca/brx-plc-compare-instructions Compare Instructions Video https://youtu.be/CIDVcM0zszE BRX PLC Math Instructions https://accautomation.ca/brx-plc-math-instructions Math Instructions Video https://youtu.be/ZllosAv0DyY Program Control https://accautomation.ca/brx-plc-program-control Program Control Video https://youtu.be/1fewvxxUyW4 Shifting Instructions https://accautomation.ca/brx-plc-shifting-instructions Shifting Instructions Video https://youtu.be/FVTxIl8VKmg There are several reasons why we are using the BRX Series Controller. Here are just a few. - Standalone PLC with built-in I/O - Built-in Data Logging - Communication ability - Ethernet Port, RS232, RS485, USB - support for protocols such as Modbus RTU, Modbus TCP, ASCII, K-sequence (DirectLOGIC users), Custom Protocols (ASCII over serial, TCP or UDP over Ethernet) - Built-in Analog input and output - Integrated motion control - High-speed counters - Powerful instruction set (Video of Instructions in software) - Ability to expand the system with a variety of modules - Part of the Do-More series of PLCs which use the same free software. (Do-More Designer) - Integrated simulator in the software capable of external communications for testing The BRX series of programmable logic controllers consist of four different units. They differ depending on the Inputs and Outputs built into the unit and if it has an ethernet port. No I/O Micro PLC unit – (BX ME) 10 Point Micro PLC unit – (BX 10/10E) 18 Point Micro PLC unit - (BX 18/18E) 36 Point Micro PLC unit - (BX 36/36E) These CPUs (Central Processing Units) are also known as MPU (Multi-Processing Units) because of the communication capabilities. https://www.accautomation.ca
