We know that a communication bus can be divided into many levels. Taking the CANBUS bus as an example, it can be divided into:

1. Application layer

2. Presentation layer

3. Session layer

4. Transport layer

5. Network layer

6. Data link layer

7. Physical layer, etc.

Among them, the application layer is the highest layer, which requires a bus protocol to specify all aspects of communication. In the face of some high-level bus protocols, the common data converters are powerless. For example, CANBUS to Ethernet converters are very common, but there are not many converters that can realize CANopen to Ethernet. In order to meet the conversion between these bus data with high-level protocols, we have developed a variety of programmable gateways, integrated with a variety of bus communication interfaces, and can realize data editing with the help of PLC programming language.
