28922-5 is a type of standard for industrial automation systems which is part of the IEC 61158 family. It is an application layer protocol that provides communication between different devices such as Programmable Logic Controllers (PLCs) and Human Machine Interfaces (HMIs). 28922-5 uses a master-slave approach to communication, where one device acts as the master while the other acts as the slave. The master initiates the communication and controls the data flow, while the slave responds to the requests of the master. It was designed for a low-level communication between devices and thus does not require any complex data structures.

One of the main advantages of this standard is that it allows different devices to communicate with each other irrespective of their manufacturer or the protocol they use. It provides a common language that the different devices can understand and use to transfer information. This makes it easier for systems to be integrated and configured quickly.

The main working principle of 28922-5 is based on a request-response mechanism. When the master initiates a communication, it sends out a message that contains a request. The slave receives this request and then sends back a response. The response provides information about the status of the data that was requested. The response can then be used by the master to further control the device or request more data. This communication process continues until the master is satisfied or the communication is terminated.

28922-5 is a widely used standard in the industrial automation field as it is robust and reliable. It has been adopted by many companies in the automation industry due to its ease of integration and flexibility. It is also relatively easy to implement, which makes it an attractive option for the automation system designer.

In summary, 28922-5 is an application layer protocol that provides communication between different devices. It is widely used in the industry due to its robustness, reliability, and ease of implementation. It works on a request-response message structure which allows the devices to communicate and transfer data. This makes it an ideal choice for the automation system designer.
