FOXBORO FBM215 controller

The FOXBORO FBM215 is a controller from Foxboro. The system programs in the FBM215 controller are important data that need to be stored for a long time, so the memory is ROM(read-only memory) or EPROM(electrically erasable read-only memory). ROM is characterized by can only read content, can not write content, and has non-volatile, that is, after the power is disconnected can still save the stored content. EPROM, on the other hand, must use ultraviolet light on the lens window on the chip to erase what has been written.

In addition, the FBM215 controller has a user program memory for storing user-loaded PLC applications. The initial user program is called the user debugger because it needs to be modified and debugged, and these programs are stored in the random access memory RAM that can be randomly read and written to facilitate the user to modify and debug.

The reason why PLC has a strong vitality is that it is more suitable for the requirements of industrial sites and markets, with high reliability, strong resistance to various interference, programming installation and easy to use and long life. Compared with the single chip microcomputer, the input and output end of the PLC is closer to the field equipment, and it does not need to add too many intermediate parts or need more interfaces, thus saving the user's time and cost.
