EMERSON A6210 Thrust Differential Expansion Module

The EMERSON A6210 on-site control layer, as the underlying part of the entire enterprise information system, inevitably needs to be integrated with the process management layer and business decision-making layer. This also poses the problem of how monitoring computers communicate and transmit information with other computers. Due to the fact that control systems are often specialized systems developed by different manufacturers, with poor compatibility and a lack of effective communication interfaces with high-level commercial management software, communication specification issues have become a bottleneck that restricts control systems from breaking through “information silos”.

A set of communication interface specifications that meet industrial control requirements has been established, enabling control software to efficiently and stably access data from hardware devices. Application software can also flexibly exchange information, greatly improving the interoperability and adaptability of control systems
From a software perspective, EMERSON A6210 can be seen as a standard for a “software bus”. Firstly, it provides a channel standard for real-time data transmission between different applications (even between applications on different workstations connected through a network); Secondly, it also defines the format for transmission and exchange in channels for process control needs. The architecture of the OPC standard is the client/server model, which divides software into OPC servers and OPC clients. The OPC server provides necessary OPC data access standard interfaces; OPC customers access OPC data through this standard interface.
