Often times remote applications are the area where we find it difficult to penetrate and get the proper information. OPC UA scalability helps to provide the solution by being in the server for smaller devices.
We talk a lot about application related to real time system, the study describes the Operating system and real time in depth.
A lot of different types of communication protocol is needed for communication between the devices but is it different from OPC UA.
Without any communication protocol, Industry 4.0 is also just a term. So, the usage of OPC UA platform in Industry 4.0 has been explained.
RFID systems has been explained in terms of its origin.
Industry 4.0 is a new era in the industrial domain where the target is towards digitalization but focuses also need to be detailed out.
