In general, systems such as SCADA, MES, POP, and Home Network include field control such as central control room, monitoring system, programmable machine interface (PLC), remote terminal unit (RTU), distribution control system (DCS), and graphic pannel (GP). In many cases, the same configuration as the system is included and the Internet and the intranet are built.

It can be seen that the field control system, that is, industrial automation system, is connected to various measuring instruments such as motors, pumps, blowers, distributors, temperature sensors, etc., and the connection method is via a communication means such as Ethernet or serial.

When interconnected measuring instruments or industrial automation systems are heterogeneous with each other, processing of data is processed and converted through the control of the field, which is transmitted to the network and transmitted to a server or a central control room.

1 is a block diagram schematically showing a field control system control structure according to the prior art.

As can be seen from Figure 1, the conventional field control system has often used a PC to process and convert the heterogeneous data, in this case the cost rise problem occurs because a separate computer must be installed at each remote location There is a problem that a large manpower is required in the installation operation.

Not only does it provide a specific means, but it is also unclear whether there is sufficient compatibility with various automation devices and automation systems. In addition, by simply managing the data input and output of the device, a PC that can perform the data processing process functions that can selectively screen the operation data or configure in the form of a conditional statement is eventually required.

In addition, when a large amount of data is input or output from the measuring device in real time, data bottlenecks may occur, and there is no mention of a specific method to solve this problem, which has an unstable structure that may cause system overload. do.
