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.
