BRX Do-More PLC Control Logic - Ladder Logic Execution

BRX Do-More PLC Control Logic $Main is the primary code-block of ladder logic that executes every scan. There are optional system tasks like $tTopOfScan, $tBottomOfScan, $t1Second that can help isolate logic that needs to execute at specific places or times. Each of these code blocks will be displayed in its own Ladder View. You can create your own user code-blocks. Programs and Tasks are executed a little differently from each other. Subroutines can be called in-line from any Program, Task, or Subroutine. Interrupt Service Routines are helpful when the timing is crucial. See Do-more Designer's Help Topic DMD0231 Code Block Overview for more helpful information. Programming and examples of the BRX Do-More series can be found at this URL: https://accautomation.ca/series/brx-do-more-plc/ General information on the BRX Do-More series of controllers: https://www.automationdirect.com/do-more/brx There are also system configuration tools that will calculate the power budget, I/O count, and price. BRX Do-More PLC Configuration: https://www.automationdirect.com/do-more/brx/config There are several reasons why we are using the BRX Do-More 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)
