BRX Do-More PLC HTTP JSON Instructions

We will now look at the BRX Do-More HTTP JSON instructions in the PLC. One of the features of the BRX Series PLC is the ability to expand its capability to fit your application. Software and hardware changes are ongoing so the PLC can grow with your needs. Communication is something that the BRX PLC can do very well. As part of the internet of things (IoT), the BRX will share and exchange data. This will suit several industrial applications. The Do-more Updates Release 2.5.2 on April 22, 2019, has introduced new instructions. Here are the instructions that we will be using: HTTPCMD – HTTP Request / Response with Server (BRX only) JSONPARSE – Parse JSON Text (BRX only) We will be using these instructions to read the weather conditions from a website. Let's get started. More information can be obtained on our website. This includes all of the links mentioned in this video. https://accautomation.ca/brx-plc-http-json-instructions The entire BRX Series PLC can be found at the following location: https://accautomation.ca/series/brx-do-more-plc/ Here are the individual posts with video links: System Hardware https://accautomation.ca/brx-plc-system-hardware https://youtu.be/wSYgY09VYeA Unboxing Video https://youtu.be/-Tf8m3BqzPo Installing the Software https://accautomation.ca/brx-plc-installing-the-software https://youtu.be/iFI1ebP8Zkk Establishing Communication https://accautomation.ca/brx-plc-establishing-communication 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 https://youtu.be/-GiKnIDycKY First Program https://accautomation.ca/brx-plc-first-program https://youtu.be/ANSNhdlm_Ao Monitoring and Testing the Program https://accautomation.ca/brx-plc-monitoring-and-testing-the-program 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 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 Drum Instruction https://accautomation.ca/brx-plc-drum-instruction Drum Instruction Video https://youtu.be/ILokPN1Aadk Serial Communication – Modbus RTU to Solo Process Temperature Controller https://accautomation.ca/brx-plc-serial-communication-modbus-rtu-to-solo-process- temperature-controller Serial Communication Video https://youtu.be/PndrIfBImGQ Data Logging https://accautomation.ca/brx-plc-data-logging Data Logging Video https://youtu.be/OBv7XJ9mJeA Email – Text SMS Messaging Gmail https://accautomation.ca/brx-plc-email-text-sms-messaging-gmail Email Video https://youtu.be/0L74qOwwWAE Secure Email Communication https://youtu.be/hhVawCL3ztU AdvancedHMI Communication – Modbus TCP https://accautomation.ca/brx-plc-advancedhmi-communication-modbus-tcp AdvancedHMI Communication Video https://youtu.be/1TjsdLwTKM0 BRX PLC Analog IO – System Configuration https://accautomation.ca/brx-plc-analog-io-system-configuration Video https://youtu.be/WmdbalWwO6E 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 the 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
