Solution Overview

Problem

The parametering of field devices in industrial plants is complex due to the large number of parameters, requiring significant effort and often necessitating the physical presence of service technicians, leading to costly and time-consuming travel for maintenance and troubleshooting.

Innovation Solution

A method and system for remote-controlled servicing of field devices, allowing a service technician to access and service field devices from a distance using a communication network, with an application program like SmartBlue that enables parameterization, data visualization, and diagnostic tasks through a computer unit connected via a network, eliminating the need for on-site presence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If service technicians physically travel to field device locations for parametering and maintenance, then direct hands-on servicing is achieved, but travel time and costs increase significantly

Engineering Contradiction:
Improvedirect servicing capabilityVSAvoidtravel time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent creates a virtual copy of the field device through a graphical user interface that replicates the device's parameters, settings, and operational states. Service technicians can interact with this virtual representation remotely, performing parametering, diagnostics, and maintenance tasks without physical presence at the field location, thereby eliminating travel time while maintaining full servicing capability.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces a communication network and software platform as intermediaries between the service technician and the field device. The graphical user interface acts as a mediator that translates technician commands into device operations and device status into visual representations, enabling remote interaction without direct physical connection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If service technicians physically travel to field device locations, then on-site troubleshooting is achieved, but operational disruption increases

Engineering Contradiction:
Improveon-site troubleshootingVSAvoidoperational disruption
Core Design Contradiction:
Ease of repairVSProductivity

Solution Approach 1:

By creating a real-time virtual copy of the field device through the graphical user interface, the system enables service technicians to perform troubleshooting and diagnostics remotely. This eliminates the need for technicians to travel to field locations, allowing process operations to continue uninterrupted while maintenance and troubleshooting activities are performed on the virtual representation.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If field devices have comprehensive parametering options, then functionality and adaptability are improved, but complexity of parametering increases

Engineering Contradiction:
Improvedevice functionalityVSAvoidparametering complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the comprehensive device parameters into organized categories and hierarchical groups within the graphical user interface. This segmentation allows service technicians to access and modify specific parameter groups relevant to their tasks without being overwhelmed by the complete set of device parameters, thereby maintaining device versatility while simplifying the parametering process.

Inventive Principle:
Principle #1Segmentation
