A bridge connected between a first process control loop and a second process control loop wherein the bridge allows alternating current digital signals to pass between the first process control loop and the second process control loop while preventing direct current analog signals from passing between the first process control loop and the second process control loop.

Techniques for assessing and presenting differences between the current commissioning data of a set of process control devices within a process plant and the respective baseline or defined commissioning parameters of the set of process control devices. According to embodiments, systems and methods may obtain the current commissioning data from the set of process control devices and access baseline parameters corresponding to the commissioning data. The systems and methods may compare the current commissioning data to the baseline parameters to determine a set of differences, and present, via a user interface, the set of differences for review by an administrator. In reviewing the set of differences, the administrator may facilitate different functionalities including rebaselining or reconfiguring process control devices.

A distributed control and/or monitoring system and method includes a local application and a remote application separated from the local application. The local application includes a host computer. The remote application includes a plurality of field devices and a communication bus connected to the plurality of field devices. Packet messages are wirelessly communicated between the local application and the remote application such that the host computer and field devices can communicate with each other as if they were directly connected to the same communication bus.

A device comprises a sensor tube for placement in a process flow and a flow-modifying element. The flow-modifying element is formed on the sensor tube, in order to reduce flow-induced vibrations by reducing coherent vortex shedding in the process flow.

An industrial process sensor having a sensor component exposed to process fluid detects when the sensor performance has been degraded by a sensor coating buildup from the process fluid. A baseline statistical metric, such as standard deviation of the process parameter sensed by the sensor, is determined during an initial operating period when the sensor component is clean. During continued operation of the sensor, the statistical metric is continually updated and monitored. An alarm output indicating that sensor coating has degraded sensor performance is produced when the current value of the statistical metric varies from the baseline value by an amount indicating degraded sensor performance.

An interface module is operatively coupled to a Fieldbus process control network and a Modbus process control network to facilitate the exchange of process control information between the networks. The interface module stores a register map database in which the process control parameters of the function blocks in the field devices of the Fieldbus process control network are mapped to register numbers of the Modbus process control network. Once the Fieldbus process control parameters are mapped to the Modbus registers, the interface module is adapted to transmit request messages on the Fieldbus process control network to the Fieldbus field devices for the current values of the process control parameters, receive response messages from the Fieldbus field devices, and store the current values of the process control parameters in the register map database.

An interface module is operatively connected to a Fieldbus process control network and to at least one non-Fieldbus process control network to facilitate the exchange of process control information between the networks. The interface module stores a database in which the process control parameters of the function blocks in the field devices of the Fieldbus process control network are mapped to corresponding process control parameters of the non-Fieldbus process control network. Once the Fieldbus process control parameters are mapped to the non-Fieldbus process control parameters, the interface module is adapted to transmit request messages on the Fieldbus process control network to the Fieldbus field devices for the current values of the process control parameters, receive response messages from the Fieldbus field devices, and store the current values of the process control parameters in the database. The interface module may also function in the other direction to map non-Fieldbus process control parameters to corresponding Fieldbus process control parameters.
