Even if PLC breaks down, maintenance is very convenient. This is because the PLC has many error indication signals, such as insufficient battery voltage in the PLC supporting memory to maintain data, and corresponding low voltage signal indication. In addition, PLC can also detect the fault status. Therefore, it is easy to diagnose PLC errors. At the same time, troubleshooting after troubleshooting is very simple. It can be classified according to modules, and spare parts of modules can be purchased in the market and can only be replaced.
