Abstract:
In a method for maintaining a production installation having a plurality of field devices F1, F2, F3 connected partly, or completely, over a data bus D with a control system L, the field devices F1, F2, F3 are registered in a manufacturer data base HG-DB with a manufacturer-specific identification and manufacturer-specific information relevant for maintenance, and in a customer database IB-DB with a customer-specific identification and customer-specific information. An electronic database query on the basis of maintenance criteria is performed in both of the databases HG-DB and IB-DB. In this way, both manufacturer information and customer information can be considered in the maintenance process.
Abstract:
A process control routine may include a first internal function block for executing a control operation based on an input signal and an information conduit communicatively connected to the first internal function block. The information conduit may have an output adapted to provide the input signal to the first internal function block. The process control routine may further include an external function block communicatively connected to the information conduit and adapted to generate the input signal such that the output signal is directly provided to the information conduit prior to the execution of the control operation.
Abstract:
An auto-tuner is adapted to be used in a distributed process control network having a communications network that communicatively couples a process controller, which executes a process control routine, and one or more process devices used in a process control loop. The auto-tuner includes a first tuning element configured to cause a control entity to force the process loop to undergo an auto-tuning procedure and a tuning data stack operating within one of the process devices to receive and store a tuning signal associated with the control entity along with a time stamp indicating the time the tuning signal was acted on by the device. A measurement data stack is disposed in the same or a different process device and operates to receive and store a response or measurement signal generated by the process device along with a time stamp indicating when the response signal was generated or detected. A second tuning element which may be, for example, in a controller or a workstation, periodically receives data from the tuning data stack and the measurement data stack and determines a tuning parameter to be used in tuning the process loop.
Abstract:
The present invention relates to a field bus system for controlling safety-critical processes. The system has an open channel transmission medium and a plurality of bus subscribers connected to the transmission medium. The bus subscribers are configured to transmit bus messages via the transmission medium in order to communicate with each other. The system further has a defined communication protocol which predetermines rules for the transmission and reception of bus messages. The communication protocol includes an individual system identifier which is connected at least to each bus message transmitted via the open communication channel.
Abstract:
A configuration system for use in a process control network having a controller, a first device network that communicates using a first input/output protocol, such as a Fieldbus or a HART device protocol, and an AS-Interface device network that communicates using an AS-Interface input/output communication protocol includes a configuration database that stores configuration information pertaining to the first device network and configuration information pertaining to the AS-Interface device network, a data access routine that automatically requests configuration information pertaining to the first device network and configuration information pertaining to the AS-Interface device network and a configurator that configures the AS-Interface device network based on the AS-Interface device network configuration information. The configurator stores the AS-Interface device network configuration information in the configuration database along with configuration information pertaining to the first device network. A documentation routine accesses the configuration database to display a process control documentation schematic illustrating the configuration of the first device network and the AS-Interface device network within the process control system.
Abstract:
An automation device includes a master module, and a slave unit having a slave modules, where an interface module (IM) of the slave modules of the slave unit is connected to the master module via a bus, where each of the modules is parameterizable using a message transmitted to the IM by the master module, the message includes a data area for each of the slave modules for parameterization of each of the slave modules, and the message includes a data area for each slave module for its parameterization, wherein at least one default parameter data record is stored in at least one of the slave modules, and wherein a data record index, which is stored in that data area of the message which is provided for the at least one slave module is provided for accessing the at least one default parameter data record.
Abstract:
Systems and methods for simulating operations of a Fieldbus system (FS). The FS (200) includes a Fieldbus interface module (FIM) coupled to field devices. The methods involve creating a simulation computer model (SCM) of the FS, generating simulation data records (SDRs), and running simulation software (SS). The SS is installed on a computer system (242), FIM (232, 234), or embedded device (222, 226). The SS simulates at least one operation of the FS. The SS uses at least a portion of the SCM and at least one of the SDRs. The SCM includes functional blocks and interconnections between the functional blocks. The functional blocks represent the FIM and/or field devices. The SDRs include data defining the SCM, a control strategy of the FS, and communication links between the FIM and field devices. The SDRs also include data defining the operating characteristics of the FIM and field devices.
Abstract:
An industrial process control system is provided that includes one or more fieldbus devices configured to communicate alarm or alert information representative of alarms and alerts using a first format. The industrial process control system also includes a linking device connected to the one or more fieldbus devices that is configured to publish the alarm or alert information from the fieldbus devices to one or more computers of the industrial process control system. A controller is also included that is configured to receive the alarm or alert information from the linking device. The controller is configured to interpret the alarm or alert information and create a list of the alarms and alerts in a second format interpretable by an alarm server of the industrial process control system, wherein the alarm server cannot interpret the first format.
Abstract:
