What does the T R indicator of a programmable controller mean when it flashes?

This indicator is flashing, indicating that the circuit is unstable.

It could be that there is a problem with the circuit, or that the motherboard is faulty.

What does the elaboration of a programmable controller mean? Is this some flickering in memory or some piece of software?

The tr of the programmable controller is just waiting for this to flash, it may be that he has some faults, and he always flashes to remind you about this.

What does the 2 t indicator of the programmable controller mean when it flashes? I don't know much about this, I don't have this knowledge anymore.

The programmable controller's nucleus indicator flashes.

The development of microprocessor technology and storage technology is very rapid, with more powerful functions and cheaper, and the microprocessors developed are more targeted. This provides a good environment for the development of programmable controllers. Most of the large-scale programmable controllers adopt multi-CPU structures, and continue to develop in the direction of high performance, high speed, and large capacity.

In terms of analog control, in addition to the PID instructions and intelligent PID modules specially used for analog closed-loop control, some programmable controllers also have fuzzy control, self-adaptation, and parameter auto-tuning functions, which reduce the debugging time and improve the control accuracy. 2.Development in the direction of popularization Due to the cheapness, small size, light weight and low energy consumption of the micro programmable controller, it is very suitable for stand-alone automation, and its external wiring is simple, easy to realize or form a control system, etc., and has been widely used in many control fields.

At present, learning computer science is still very good and good employment, computer is divided into many majors such as graphic design, UI design, Internet marketing, e-sports, animation, are very good employment majors, choose your favorite major.

You should learn the principles of operation before you learn the programming language. Once you understand the principle, the rules of the language will be easy to understand.

Basically, they all learn together.

Hardware descriptions need to be exaggerated. Software programming needs to be short and lean, but it is impossible for the two to be separated, and finally unite together to cheat the buyers!

If you go to a first-class computer technology college and study hard with a reliable teacher, why bother with how to study in it? It's very inefficient to figure it out on your own like yours, and it's only a few people who are self-taught.

C is the closest high-level language to hardware, and it is also the most important language in computers, so it is recommended that you learn it first.

Verilog HDL's program burning into the chip will affect the circuit structure in the chip C After compiling into machine code, it is generally run on a general-purpose computer This problem is very big, and I don't know where to start, but I tried my best.
