1. Choice of power module The choice of power module is relatively simple, only need to consider the rated output current of the power supply. The rated current of the power supply module must be greater than the total current consumption of the CPU module, I/O module, and other modules. The choice of power supply module is only for PLC with modular structure, and there is no power supply choice for integral PLC.

2. Selection of programmers For small control systems or PLC systems that do not require online programming, a simple and cheap programmer is generally used. For a complex system composed of medium and high-end PLCs or a PLC system that requires online programming, a smart programmer with strong functions and convenient programming can be selected, but the smart programmer is more expensive. If there is a ready-made personal computer, you can choose the PLC programming software package to realize the function of the programmer on the personal computer.

3. Selection of the writer In order to prevent users and programs in the RAM from being destroyed due to interference, such as changes in the lithium battery voltage, an EPROM writer can be selected, through which the user program is solidified in the EPROM. Now some PLC or its programmer itself has the function of EPROM writer.
