Wireless Commissioning for Unpowered Process Control Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The commissioning process of process control systems in industrial plants is complex and time-consuming, requiring physical devices to be installed and interconnected in the field environment, with dependencies between back-end and field environments that prolong the overall commissioning time and increase resource requirements.
Innovation Solution
Smart commissioning techniques allow for partial or complete commissioning of process control systems to be performed locally and automatically, enabling commissioning activities to take place in parallel and independently in both the field and back-end environments, even before devices are powered on, using wireless communication links to transfer commissioning data to unpowered components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional commissioning processes are used with physical device installation and interconnection in field environment, then devices can be properly configured and integrated, but commissioning time and personnel resources are significantly increased
Solution Approach 1:
The patent applies preliminary action by enabling commissioning activities to be performed before devices are powered on and before physical interconnections are completed. Configuration data is prepared and transferred in advance to unpowered components, allowing commissioning work to proceed parallel to physical installation activities rather than sequentially, thus reducing overall commissioning time while maintaining configuration accuracy
Solution Approach 2:
The patent uses wireless communication as an intermediary to transfer commissioning data between powered and unpowered components. This intermediary mechanism enables data exchange without requiring physical connections or power to the target device, decoupling the commissioning process from physical installation constraints and reducing both time and resource requirements
2Reliability
If commissioning is performed after devices are powered on and physically interconnected, then proper system integration is achieved, but commissioning activities cannot proceed in parallel, increasing overall commissioning duration
Solution Approach 1:
The system performs commissioning actions in advance by transferring configuration data to unpowered components before they are powered on or physically connected. This preliminary commissioning allows configuration work to proceed independently and in parallel with physical installation, increasing commissioning throughput while ensuring system integration integrity when devices are eventually powered and connected
Solution Approach 2:
The patent segments the commissioning process into independent phases that can occur separately: data preparation and transfer phase (before power/connection) and verification/integration phase (after power/connection). This segmentation allows different teams to work on different aspects simultaneously, improving overall commissioning productivity without compromising system integration
3Ease of operation
If wireless communication is used to transfer commissioning data to unpowered components, then commissioning can occur before devices are powered on, but additional communication infrastructure is required
Solution Approach 1:
The patent leverages the universality of wireless communication technology, which is already widely deployed in industrial environments for other purposes. By using existing wireless infrastructure (Wi-Fi, Bluetooth, cellular) for commissioning data transfer, the system gains operational flexibility without adding significant complexity, as the communication capability serves multiple functions including commissioning, diagnostics, and operational data exchange

AI summary
Techniques for commissioning a process control device in a process plant include obtaining, at a portable computing device, commissioning data for commissioning the respective process control device for operation, such as a device tag. The portable computing device then transfers the commissioning data to a component in the same process control loop as the process control device via a wireless communication link. For example, the component includes a radio-frequency identification (RFID) or near field communication (NFC) unit for receiving RFID/NFC signals. When the portable computing device is within RFID/NFC communication range of the component, the commissioning data is transferred via an RFID/NFC signal to the component. The commissioning data is received while the component is in an unpowered state, where the RFID/NFC signal energizes the RFID/NFC unit at the component for receiving the signal.
