BRX Do-More PLC Analog Dusk to Dawn Program

We will now look at a BRX Do-More PLC Analog example program. A dusk to dawn sensor usually is discrete on/off of the lighting control. If we want to vary the lights to mimic more of the sunset and rise, we would use an analog output to control the lights. I was recently asked about such a program. Every day they wanted the lights to go off at 10 pm and come back on at 6 am. At 9:30 pm the lights would be on at 70% or 7volts of a 0-10V signal. In the next half hour, the program will bring the lights from 70% down to 0%. In the morning the lights will come back on within the half-hour from 0% to 70%. Poultry Farms are one place that would utilize this program. We will be developing a program that will do this with our BRX PLC (Do-More). Let’s get started!

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 Instructons 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
