Embodiment Construction

[0044] A general industrial controller according to the present invention includes a general industrial computer, a control bus and a controller, and the controller includes a field bus scanner 1, a target object manager 2, a control strategy scanner 3 and a redundant pair manager 4 . The field bus scanner 1 realizes the reception and transmission of real-time data on the control bus, and realizes the switching of the redundant field bus through the inspection of the control bus, and notifies the relevant detection information to the control strategy scanner 3, and then manages the data through the target object The controller 2 outputs the alarm or detection information to the relevant nodes of the control bus; the target object manager 2 is a standardized universal interface for data transmission on the control bus, which can transparently access all real-time data of each node on the control bus, and can Dynamically increase or decrease the number of nodes; the control stra...

Abstract

The invention discloses a general industrial controller, including a general industrial computer, a control bus and a controller. The controller includes site bus scanners, target manager, control strategy scanners and redundancy couple manager. The site bus scanner realizes the reception and sending of the real-time data on control bus. The target manager conducts a transparent visit to all the real-time data on all the nodes of control bus and can regulate the number of nodes. The control strategy scanner makes each node use different general industrial computer to operate according to different functions, and manages on-line and schedules each control function block. The redundancy couple manager realizes the mutual interaction between the two machines for hot standby, to judge their own state and other state to inform each other, and switch when necessary, and transmit the data for the inverse calculations of guard machine function block.

Description

1. Technical field [0001] The invention relates to a core component of an industrial automation control system, in particular to a general industrial controller. 2. Background technology [0002] With the development of industrial automation technology, distributed control system (DCS) began to enter various automation control fields on a large scale. The DCS controller with high reliability and availability is the core component of the entire distributed control system. Only with the support of the DCS controller with high reliability can a powerful and stable DCS control system be built. As the core of the distributed control system, its process controller (DPU) requires high reliability, and with the expansion of the project scale, the same system needs to be flexible in order to realize different scale applications. On the one hand, after a system is put into operation, the control system will need to be modified due to changes in the environment or requirements, such a...
