Industrial Automation

This image depicts the hierarchical structure of an industrial automation system.

At the lowest level, the Internal Works handle the internal control of individual devices.

At the Controller Works level, separate PLCs (Programmable Logic Controllers) are used for control because the computing power of the equipment itself is insufficient for complex program control.

The Group Works level integrates and manages groups of similar or identical equipment.

The Integration Works level integrates all the equipment through PLCs.

At the highest level, there is a database, HMI (Human-Machine Interface), monitoring/analytics systems, etc. This integrated analytics system does not directly control the equipment but rather manages the configuration information for control. AI technologies can also be applied at this level.

Through this hierarchical structure, the entire industrial automation system can be operated and managed efficiently and in an integrated manner.

Down data

I can interpret the contents of this image as follows:

  1. Sampling is a method to reduce the “Down Count”, i.e., the number of data points, by extracting only a subset of the entire data.
  2. Roll Up is a method to reduce the “Down Count” by aggregating data over time units. The aggregation functions (Count, Sum, Avg, Max, Min, etc.) are included as examples to help understand the concept of Roll Up.
  3. Quantization is a method to reduce the data size (“Down Size”) by converting floating-point numbers to nearby integers.
  4. “And More…” mentions additional data reduction techniques like Sparse Data Encoding, Feature Selection, and Dimensionality Reduction.

Overall, the image effectively explains how Sampling and Roll Up reduce the number of data points (“Down Count”), while Quantization reduces the data size (“Down Size”).

Register in a CPU

This image explains the registers within the CPU and their purposes. Registers are small, high-speed memory locations inside the CPU that serve various roles.

GPR (General Purpose Registers) are used for calculations, logical operations, etc. (like variables). SP (Stack Pointer Register) remembers the memory location of the stack for calling functions, passing parameters, and managing local variables. BP (Base Pointer Register) refers to the current/next data location within a data structure. PC (Program Counter Register) is the command currently executing, used by the CPU to decide which instruction to execute next. Status Register detects abnormalities resulting from operation performance and handles them.

It also mentions that there are more registers such as indexes, counters, timers, flags, and more.

Abstraction/Overlay with Software-defined

This image illustrates the concept of abstraction and overlay using software-defined systems. At the top, it shows hardware represented by servers, software as a user interface, and control as a cursor icon. Below, it demonstrates that complex hardware becomes more abstracted through software-defined systems.

The software layer acts as an overlay that simplifies and abstracts the underlying complex hardware infrastructure. This logical abstraction enables automated control and management of the hardware resources through software interfaces.

The image conveys how software-defined approaches decouple the control and management functions from the physical hardware, enabling more flexibility, scalability, and automation in managing IT infrastructure. The progression from hardware to software, and then to logical abstraction and automated control, highlights the benefits of software-defined systems in modern computing environments.

TCP Reliable 3

RTT is measured by sending a packet (SEQ=A) and receiving an acknowledgment (ACK), providing insights into network latency. Bandwidth is measured by sending a sequence of packets (SEQ A to Z) and observing the amount of data transferred based on the acknowledgment of the last packet.

This image explains how to measure round-trip time (RTT) and bandwidth utilization to control and optimize TCP (Transmission Control Protocol) communications. The measured metrics are leveraged by various mechanisms to improve the reliability and efficiency of TCP.

These measured metrics are utilized by several mechanisms to enhance TCP performance. TCP Timeout sets appropriate timeout values by considering RTT variation. TIMELY provides delay information to the transport layer based on RTT measurements.

Furthermore, TCP BBR (Bottleneck Bandwidth and Round-trip propagation time) models the bottleneck bandwidth and RTT propagation time to determine the optimal sending rate according to network conditions.

In summary, this image illustrates how measuring RTT and bandwidth serves as the foundation for various mechanisms that improve the reliability and efficiency of the TCP protocol by adapting to real-time network conditions.

Automation

This image visually illustrates the automation process and emphasizes its long-term potential and impact. While automation may appear to be a small improvement at the present moment, the image highlights that with an accurate and systematic configuration, continuous utilization of automation over an extended period can lead to significant growth and advancement.

Initially, the computed output exhibits a gradual upward curve labeled “Small Up at making time.” However, as indicated by “Must be accurate,” precision is a prerequisite for realizing the full potential of automation. If accuracy is ensured, the sharp upward trend depicted as “Finally Big UP after a long time (if accurate)” can be achieved over the long run.

Therefore, the image suggests that although automation may seem like a small step currently, with precise and sustained implementation, it has the potential to yield substantial gains and achievements over time.
