We will now use the Do-More Designer software to establish communication with the BRX Do-More PLC. This is the same software that we used in the Learn PLC Programming Fee Video Series. Using the Do-More Designer software, we will communicate via USB, RS485, and Ethernet. These three methods will allow us to communicate to our BRX Do-More PLC in order to program or troubleshoot this controller. Once we have established communication we will then look at updating the firmware in our controller. Let’s get started.
