Practical Tips and Techniques
We will now look at online editing and the powerful debug mode of our BRX Do-More controller. Our first program for the BRX Do-More PLC involved a start-stop jog circuit. We will now use the Do-More Designer Software to modify this program while the PLC is scanning the logic. This is referred to as online … Read more
The BRX PLC uses the Do-More Designer software which can be downloaded free of charge and includes a simulator. The latest Do-More Designer software version is 2.0.3. This is the same software that we used in the Learn PLC Programming Fee Video Series. The Do-More Designer software can be used to program the whole series … Read more
The BRX Do-More series of programmable logic controllers is a stackable micro brick. This is sometimes also referred to as a shoebox PLC because of the shape and way in which expansion modules are added. This new BRX Do-More series PLC is the latest in the Do-More series of controllers that have hit the market. … Read more
In part 1, we looked at writing PLC programs to control a traffic light using discrete bits and timed sequencing using indirect addressing. We will now look at how we can use indirect addressing for inputs and output to control the sequence in the program. Let’s look at an example of controlling pneumatic (air) cylinders. … Read more
Programmable Logic Controllers (PLC) will scan very quickly. This can be anywhere from 1 to 20 ms, translating into 1000 to 500 times each second. But what exactly is a scan? A scan is when the PLC will complete the following: Read Inputs: Look at all of the inputs to the programmable controller. Digital, Analog, … Read more
I have always been an old-school programmer. Hardware in front of you hooked up to all of the I/O. I have recently looked at the automation direct do-more designer software solution. The Do-More Designer Software will allow you to build your ladder logic, download it into a simulator (which comes with the software), and run … Read more
