By using this protocol, a controller can communicate with other devices through transmission lines (such as RS485). It is a general industrial standard. With this standard, control devices produced by different manufacturers can be connected to form an industrial network and be monitored in a centralized way.

The CRC domain checks all the content of the frame. The CRC domain consists of two bytes, including 16 binary bits. It is calculated by the sender and added to the frame. The receiver calculates the CRC of the received frame, and compares the result with the value in the received CRC domain.
