1900/65A-01-01-01-00-00 also known as Programmable Logic Controller, is a digital operation electronic system designed specifically for industrial applications. It adopts a programmable memory that stores instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations inside, and controls various types of mechanical equipment or production processes through digital or analog input and output.
Some people say this is a pseudo problem. Microcontrollers are components, while PLCs are systems composed of components and massive software, and there is no comparability between the two in this regard. This statement is not wrong. Most PLC control chips are actually microcontrollers, which means PLC can be seen as a secondary development of microcontrollers. In terms of industrial protection level, the stability and reliability of microcontrollers cannot compare to IP67 products like PLC (IP is marked with letters, the first marked number represents contact protection and foreign object protection level, and the second marked number represents waterproof protection level). Moreover, a redundant system has been developed for products like PLC that can cope with harsh industrial environments. If the comparison between stability and reliability is meaningless, then we will analyze it from other aspects.
The 1900/65A-01-01-01-00-00  points of a 167699-02 are really limited, but what about a PLC? For different on-site signals, there are corresponding I/O points that can be directly connected to industrial devices such as buttons, switches, sensing current transmitters, motor starters, or control valves, and connected to the CPU motherboard through a bus. Almost any production line in industry has hundreds or even thousands of I/O points, which cannot be compared with microcontrollers.
