Intelligent modular unit

Abstract

The invention discloses a KM intelligent module which comprises a first data communication interface, a second data communication interface, a signal acquisition testing interface and a main CPU processor for the module. A redundant data transmission channel is formed by the first data communication interface and the second data communication interface which are connected with the main CPU processor for the module; and the signal acquisition testing interface is connected with the main CPU processor for the module. A dual bus concurrent working mode is adopted by the invention for realizing the redundant data transmission; a timing self-correcting means is internally adopted so as to avoid the problems of time drift and temperature drift of a circuit, thereby ensuring long-term reliable operation in the severe industrial environment; no adjustment means of mechanical potentiometer type is internally available and an open precision correction interface is provided; the module has perfect self-diagnostic function and can monitor various operation statuses in the interior of a clamp through a communication port; and internal software can be updated on line.

Description

technical field [0001] The invention relates to an IO module, in particular to a KM intelligent module. Background technique [0002] IO modules are input and output components used to connect field objects in various industrial automation control systems. Because the module needs to send the collected on-site switching and analog signals to the main control unit of the control system through the data transmission channel for processing, and at the same time it needs to pass various switching and analog control commands of the main control unit through The data transmission channel is sent to the IO module to control the objects on the scene. So the reliability of the data transmission channel is very important. Traditional IO modules work for a communication bus. When the communication bus fails due to an accident, the data transmission channel of the entire system cannot be smooth. Moreover, it cannot operate reliably for a long time in a harsh industrial environment, a...

Problems solved by technology

Traditional IO modules work for a communication bus. When the communication bus fails due to an accident, the data transmission channel of the entire system cannot be smooth.

Moreover, it cannot operate reliably for a long time in a harsh industrial environment, and there will be problems of time drift and temperature drift of the circuit.
