Practical Tips and Techniques
The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that are used to show different programming techniques. The robotic cell example is one of these machines. This will demonstrate a sequencer example. In this case, an engine is lifted and placed onto a rack. The logic will step … Read more
The High-Speed Input Pulse Catch will set an output that can be seen by the PLC ladder logic scan in response to an input pulse. Inputs that are too fast to reliably be seen by the ladder logic scan time will be seen. The BRX Do-More series of programmable logic controllers have built-in high-speed inputs. … Read more
The High-Speed discrete inputs can be configured to measure the amount of time between pulses. When you want a scaled value representing a speed or rate, the high-speed input timer is a better option for pulse rates below 5 kHz. This is compared to using the high-speed input pulse counting selection. The BRX Do-More series … Read more
The BRX Do-More series of programmable logic controllers have built-in high-speed inputs. These inputs can function in Counter, Timer, or Pulse Catch modes. Every CPU will have either 6 or 10 high-speed inputs (HSI) available, depending on the model. These inputs can be used for input frequencies from 0 to 250Khz. 250Khz represents 250000 input … Read more
The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that are used to show different programming techniques. The paint line is one of these machines. It will use a bit shift (shift register) to track bottles along a conveyor belt. All the bottles will be detected using photocells … Read more
We will now send email and text messages using our BRX Do-More controller. Sending email messages from the PLC sounds like an easy task. However, very few applications do this on the production floor. This is probably due to the networks involved and user authentication can be complicated. In our example, we will use a … Read more
Data logging does not have to be complicated anymore. The BRX Do-More Series PLC can log your specific data up to 32 Gigabits on a Micro SD Card. It will store your data for future data analysis in a CSV (Comma Separated Value) Txt file based on time and/or event. This is all accomplished with … Read more
We will now look at using serial Modbus RTU to communicate with a Solo process temperature controller using our BRX Do-More Controller. Serial communication instructions will allow you to send and receive serial data to an external device. The communication method that you set up can be ASCII or numeric (binary). ASCII (American Standard Code … Read more
We will now look at the drum instruction in our BRX Do-More Controller. Drum instructions are great tools when you have a simple sequence of events that need to occur at a set time interval or as a result of an event. They mimic an electromagnetic drum sequencer. The BRX Series PLC has a drum … Read more
We will now look at shifting instructions in the BRX Do-More controller. PLC shifting instructions will move bits in memory areas a fixed amount when instructed. Bits are on/off, 1 or 0, and are usually associated together to form a memory location. The memory location can be used for numbers or positions. PLC BITS NUMBERS … Read more
