Programmable Controller

Programmable Controller banner

The programmable controller has a programmable digital arithmetic logic circuit and can communicate with external devices through the I/O interface. Programmable controllers can be customized according to professional needs to meet the needs of various industrial environments and control various types of mechanical equipment.

FPGA


FPGA imageIntroduction:
The FPGA (Field Programmable Gate Array) is a collection of several digital circuits, with a large number of digital I/O pins, which can realize complex logic operations. FPGA has the characteristics of fast processing speed, parallel processing, and not easy to collapse, but its I/O interface can only accept digital logic signals, and its driving ability is poor. FPGA has strong customization and versatility, but it is hard to design its executive program.

Working principle:
1. Design the executable program according to the needs.
2. The executable file is generated by the development tool and downloaded to the FPGA through the simulator.
3. After power on, FPGA will automatically load the executable program.

The role of solid state relays:
1. Control the working status of actuators.

MCU


MCU imageIntroduction:
The MCU (Microcontroller Unit, or Single Chip Microcomputer) is a kind of integrated circuit chip, which integrates CPU, RAM, ROM, I/O interface, Timer, etc., and can be regarded as a fully functional microcomputer system. There are lots of MCU in the market, like STM32 MCU, 51 MCU, ATMEGE 328P MUC and so on. The MCU cannot be used alone, and it need peripheral circuits to execute the program.

Working principle:
1. Write the executable program directly through the computer.
2. Burn the executable file to the MCU through the burning program.
3. After power on, the MCU will automatically load the executable program.

The role of solid state relays:
1. Control the working status of actuators.

PLC


PLC imageIntroduction:
The PLC (Programmable Logic Controller) is mainly used to control various types of industrial equipment, and is composed of industrial-grade MCU and general-purpose peripheral circuits. Compared with the MCU, PLC has very strong stability and reliability: Its internal codes are strictly executed in order, and its peripheral circuits and packaging have strong anti-interference ability and high industrial protection level (IP67). The drive capability of PLC is very strong, and its I/O interface can be directly connected to industrial devices.

Working principle:
1. Write the executable program directly through the computer.
2. Load the executable file into the firmware of the PLC through the specific driver.
3. The executable file will be executed after the internal analysis of the PLC firmware.

The role of solid state relays:
1. Control the working status of actuators.
