On the strength of PLC-----Siemens, Mitsubishi and GCAN

In today's age, programming has become a well-known term. Many industrial controls are inseparable from PLC. Many companies are struggling to find high-quality PLCs. For the strength of PLC, we have systematically compared them.

1. The strength of PLC on Programming concept
    As a Japanese brand, Mitsubishi is intuitive and easy to understand, but there are many instructions.
Siemens PLC is a German brand, the instructions are more abstract, the learning is difficult, but the instructions are few.
GCAN PLC is less difficult than Siemens' instructions, and the command is less than Mitsubishi.
2. The strength of PLC on chip
  The Siemens CPU226 has a program capacity of 20K and a data capacity of 14K. The Mitsubishi FX2N has a total of 8K. Later, the 3U is improved. Siemens CPU226 and CPU224XP are equipped with two 485 ports, PPI port, and the maximum communication speed is 187.5K. All the series before Mitsubishi FX3U are a 422 port, and the speed is 9.6K.
 GCAN-PLCCore-M7 is a PLC core block, programmable, but needs to provide peripheral circuits, providing up to 4 UART, 2 CAN, 1 100M Ethernet, 8 AD, 2 DA, 40 digital inputs Output (3.3V level), 2 high-speed counter inputs and 2 PWM outputs (3.3 V amplitude). Suitable for customers to develop their own.
3. The strength of PLC on Control strength
Siemens' strengths are process control and communication control. Siemens' analog modules are cheap and simple.
Mitsubishi's advantages are discrete control and motion control. Mitsubishi's instructions are rich, with dedicated positioning commands, control servos and stepping are easy to implement, and it is also Mitsubishi's strength to achieve some complex motion control.
It has the characteristics of compact shape and high cost performance. It can be used to connect CAN bus system, Modbus system and distributed bus terminal modules, and these terminal modules can be expanded by modular means. The CAN-PLC-400 is a head with a communication interface (including Ethernet interface, RS232 interface, CAN interface, etc.), power module, central processing unit (CPU) integrated.
Knowing the strengths of all PLCs, it is right to choose the right product according to your needs.
