ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
All programmable logic controllers (PLC) have the same numbering system at their core. This is the same with all computers as well. The status of any memory location can be either on or off. A one (1) will represent an on or “True” status and zero (0) will represent an off or “False” status. This … Read more
EasyPLC Software Suite is a complete PLC, HMI, and Machine Simulator Software package. This PLC learning package includes the following: Easy PLC – PLC Simulation that will allow programming in Ladder, Grafcet, Logic Blocks, or Script. HMI System – Easily create a visual human-machine interface (HMI) Machine Simulator – A virtual 3D world with real-time … Read more
PLC memory is very similar to personal computer memory. There is the operating system and firmware of the processor and connected modules. PLC programs and data that are used by the program are also stored in the memory. We will now look at the basic understanding of memory in the PLC. Looking at two examples … Read more
PLC outputs are the next component of our PLC block diagram. The PLC program will control the outputs of the PLC. Controlling outputs is one way to get the inputs to change. We will be looking at digital and analog outputs that can be wired to the programmable logic controller. PLC troubleshooting outputs will also … Read more
PLC inputs are one component of our PLC block diagram. The output actions of the PLC will be controlled based on the inputs. We will be looking at digital and analog inputs that can be wired to the programmable logic controller. We will be looking at wiring of a normally open (NO) push button, normally … Read more
Invented in 1968 by Dick Morley, the programmable logic controller (PLC) is a simple rugged industrial computer. This free plc training series is designed for everyone to learn about these controllers. PLCs are constantly evolving and continue to be the best option for a variety of industrial automation applications. Even though the PLC is changing, … Read more
Modbus TCP will be used to connect AdvancedHMI to our BRX Do-More controller using Ethernet. Advanced HMI is a powerful, adaptable HMI/SCADA (Supervisory Control and Data Acquisition) development package that takes advantage of Visual Studio. There is no coding required and you can simply drag and drop items onto the page. The best thing is … 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 must occur at set intervals or after another event. They mimic an electromagnetic drum sequencer. The BRX Series PLC has a drum in the instruction set. Have you … Read more
