Associating And Evaluating Status Information For A Primary Input Parameter Value From A Profibus Device
First Claim
1. A method for managing Profibus device information in a distributed control system wherein a Profibus device is communicatively coupled via a network link to an I/O module assembly, wherein the I/O module assembly receives Profibus device messages from the Profibus device containing information relating to connected device modules, and wherein the I/O module assembly includes one or more tasks for extracting and processing information contained within the received Profibus device messages according to a Profibus device configuration, the method comprising:
- receiving, by the I/O module assembly, input parameter data originating from a Profibus device message issued by a connected Profibus device;
processing, by an I/O request processing task, in accordance with the Profibus device configuration, the Profibus device message by performing the additional steps of;
extracting input parameter values from the Profibus device message according to input parameter configuration entries in the Profibus device configuration, anddepositing the input parameter values in an I/O data repository on the I/O module assembly, the depositing step including storing;
a measured value for a first input parameter, anda status value for a first status parameter corresponding to the first input parameter; and
providing, by the I/O module assembly, a data status value with the measured value for the first input parameter in accordance with an I/O read operation executed on the I/O module assembly wherein the data status value is based on the status value for the first status parameter.

Abstract
A method and system are disclosed for managing Profibus device information in a distributed control system. After receiving input parameter data originating from a Profibus device message, the I/O module assembly performs steps for processing, maintaining and providing the input parameter data to a requesting control processor. The processing step includes extracting input parameter values from a received Profibus device message. The extracted input parameters are then deposited in a repository on the I/O module assembly, such that for a primary input parameter, the I/O module assembly stores at least: (1) a measured value, and (2) a status value. Furthermore, the I/O module assembly maintains a reference linking the first status parameter to the first input parameter. The I/O module assembly provides a data status value with the measured value for the first input parameter in accordance with an I/O read operation. The data status value is based on the status value for the first status parameter.
