I want to learn about *self-control skills; please give some advice

There are many discussions on such posts on the forum; you can search for them

In simple terms, interlocking means that when a measurement value exceeds a defined range, it triggers the operation of a certain device; frequency conversion is generally used to control motors

Also hope to learn*!!!:victory:

You can take a look at books on automated instruments, DCS, and process control

First, it’s necessary to understand the manufacturing process thoroughly – identify the various measurement points, determine how many automatic control loops are involved, figure out why these parameters need to be controlled, and understand what kind of interlocks exist and which processes and equipment they affect. Once the process is understood, it’s necessary to figure out how it is implemented; this requires a detailed analysis of each control loop, to determine exactly what is controlled in order to achieve the desired objectives. These should all fall under the category of craftsmanship. These functions and objectives are achieved through instruments; it is also possible to analyze each control loop to determine where the measurements come from, how the valves operate, and what effect the opening degree has on the measurement values. Variable frequency control essentially serves as a substitute for valve control; it can be considered something similar to a valve. Interlocks are also simple in logic once you understand the principles involved; for example, the interlock between a water pump and the liquid level in a tank: when the liquid level is high, the water pump is forced to shut down, or its output frequency is set to zero. This is a simple form of interlock. Once the principle is understood, if one wishes to learn more about the instrument, they can study the principles of measurement, how the actuator converts electrical signals into pneumatic signals, and the structure of the actuator. Regarding control systems, one can start by examining the configuration programs to see how input signals are transmitted from the field devices to the DCS display, what a simple control loop is composed of, and then understand how more complex control loops function and what functional blocks they consist of ； The same is true for interlocks; by understanding logical circuits, it becomes easy to comprehend configuration programs. Once one can understand these programs, they can become familiar with the functions of each functional block, and then try to create simple programs on their own, such as ones that add two numbers and display the result. Gradually, moving from simpler tasks to more complex ones, one can come to understand DCS program configuration, screen configuration, the composition of cabinets, how controllers work, as well as aspects related to power supply and network communication. Then you can use your own creativity.:lol
