Embodiment Construction

[0029] Below with the accompanying drawings Figure 1-Figure 8 The present invention is described in further detail.

[0030] An interface system oriented to DeviceNet bus. The interface system is placed between the underlying functional unit and the application layer unit. The interface system provides a standard interface for the application layer unit that has nothing to do with the DeviceNet bus device object, which can shield the details of the device object. .

[0031] The interface system is divided into upper and lower parts, the upper part is the IOServer module connected with the application layer unit, and the lower part is the ADMP (Address Mapping) module for address mapping of the underlying functional units.

[0032] The IOServer module includes a management interface of the DeviceNet bus. According to the access requirements of the application layer unit to the DeviceNet bus, the control connection is performed in the underlying functional unit to realize the ...

Abstract

The invention provides an interface system for a DeviceNet bus. The interface system is arranged between a bottom layer functional unit and an application layer unit, the interface system provides a standard interface irrelevant to a DeviceNet bus device object for the application layer unit, and different details of the device object can be shielded. The interface system is divided into an upper portion and a lower portion, the upper portion is an IOServer module connected with the application layer unit, and the lower portion is an address mapping (ADMP) module for performing address mapping on the bottom layer functional unit. The IOServer module comprises a management interface of the DeviceNet bus. According to access requirements for the DeviceNet bus of the application layer unit, control connection is performed in the bottom layer functional unit so as to achieve connection and disconnection between a device below the DeviceNet bus and a host. The interface system for the DeviceNet bus can shield the different details of the DeviceNet bus, provides the same interface for the application layer unit, facilitates debugging and maintenance of the system, achieves data acquisition of integrated circuit (IC) devices on different semiconductor bottom layer units, improves production efficiency, and reduces production cost.

Description

technical field [0001] The invention belongs to the technical field of IC equipment control, in particular to an interface system oriented to a DeviceNet bus. technical background [0002] At present, domestic semiconductor factories have invested in 12-inch wafers, and their wafer production processes are becoming more and more complex. The DeviceNet protocol is a simple, cheap and efficient protocol that is most widely used in IC equipment. The devices that can be connected through DeviceNet include from simple to Semiconductor products ranging from light barriers to complex vacuum pumps. And many production equipment may come from different equipment manufacturers, which brings difficulties to wafer processing and equipment management. [0003] In the existing IC equipment control software system, usually the application layer software directly invokes the underlying function software. If the details of the device object are changed, the upward interface of the underlyi...
