Description
LYA010A Discrete Control Module
The significance of LYA010A is that it proposes and realizes the concept of centralized control. LYA010A produced many important achievements in the field of control systems at that time, such as redundant controllers, redundant control networks (DH – Data Hiway), human-machine interfaces and so on, which are very common nowadays.
The LYA010A’s concept of centralized control is a fundamental principle of computerized process control. This concept is not only not obsolete today, but also in the future for a long period of time will be a dominant line of computerized process industrial control. The main realization of the computer control to replace the traditional instrumentation control, but not yet able to achieve advanced or optimized control, and the control scale is still small, only suitable for a set of production unit control.
According to the principle of decentralization, the entire LYA010A basic function distribution is characterized by: control network using a single layer of redundant structure; operator station is responsible for the operation and data storage; different controllers to achieve different process control and so on. This basic function distribution is still used by some control manufacturers of DCS, LYA010A produced a lot of important results in the field of control systems, such as redundant controllers, redundant control network (DH – Data Hiway), human-computer interface and so on, which are very common nowadays.
