Industrial control equipment PCBA clone and its PLC secondary development case

Date: 2016-12-16

Xinxin Technology Co., Ltd. is a high-tech enterprise integrating R & D, design, manufacturing, technology and service. Xinxin Technology has many successful PCBA clone cases in industrial control equipment such as industrial computer, PLC, servo system, inverter, sensor, industrial Ethernet, and human-machine interface. Using the world's most advanced scanning process and software technology, it can copy and stack up to 32 layers. It also has in-depth research on the difficult pcb board structure and routing rules containing laser holes, blind holes, and buried holes. A complete set of prototypes (or prototypes) provided by the customer is 100% cloned successfully in one time.



[Product introduction]

This programmable controller (PLC) is another example of Xinxin Technology's successful clone through PCB copying. The PLC processor has exceptional storage and computing capabilities, stronger communication capabilities, and more stable and reliable performance. At present, the PLC has been widely used in textile machinery, packaging, rubber and plastics, construction machinery, printing and other OEM industries and small and medium-sized projects.

[Secondary development]
Hardware secondary development
Understand the performance of the PLC products provided by customers. After the PCB is copied, a complete set of information is provided to combine with the actual needs of the customer. At the same time, the secondary design of the external circuit is developed in consideration of the software programming, and the principle wiring diagram of the electrical control system is drawn.
Software secondary development
(1) The main task of software design is to convert sequential function diagrams to ladder diagrams according to the requirements of the control system. It is best to list the software components (such as internal relays, timers, counters, etc.) used in the program design and indicate the purpose In order to facilitate the program design, debugging and system operation maintenance and inspection.
(2) Simulation debugging. Download the designed program to the PLC main unit. Add test signals from external signal sources, debug and modify and adjust the program in time until the design requirements are met.
