All About Automation, Control System and Management

Relay Control - Only on/off control can be performed. - The frequency of failure or breakdown is high and maintenance is not easy. - Circuits are modified by changing wiring. - For large-scale systems, large space and long design period are required. - Identifying the cause of a failure or an error and replacing the failed device are not easy. Sequence Control - On/off control and complex control can be performed. - Reliability is high and maintenance is easy. - Circuits are flexibly modified by using programs. - Even for large-scale systems, large space and long design period are not required, offering flexibility and extendibility. - All failures and errors can be monitored. The failed device can be replaced easily. Reference : Mitsubishi's FA E-Learning

How did I first hear about this Pyramid? It was during my third year in Myanmar when my teachers, Aung Kyaw Nyein and Nyeinkyaw Lwin, introduced this topic. In fact, this concept is like a roadmap for Factory Automation, and that’s absolutely correct. For this summary, I’ll base it on the content written by Realpars. The Automation Pyramid consists of five layers: Field Level Control Level Supervisory Level Planning Level Management Level 1. Field Level This level includes devices such as actuators and sensors. In some texts, this layer is referred to as the Physical Layer. The main idea is that these components interact with the physical world and perform real-world tasks. 2. Control Level This level involves controllers like PLCs and PID controllers, which are essential for automation engineers. These systems control the devices at the Field Level. 3. Supervisory Level The third level includes SCADA and HMI systems, which provide graphical user interfaces. To...

The Eisenhower Matrix (also known as Priority Matrix) is a task management tool that helps you organize and prioritize tasks by urgency and importance. There are only 4 tasks! Urgent, Not Urgent, Important and Not Important. You can use this technique based on your experiences in different field. Reference : Asana

We can control the parameters with better resolution owing to the MSB and LSB. The most significant bit is denoted by MSB, and the least important bit by LSB. The left-most bit in binary is known as the MSB, because it has the biggest impact on the number. For instance, 0011 would be the Most Significant 4 bits in the binary integer 0011 0101. 0101 would be the four least significant bits. The most significant bit (MSB) and least significant bit (LSB) are mainly utilized in industrial automation for data interpretation, control logic implementation, and communication protocol setting (endianness).
