Skid Communicator Network Profile Switching for Secure Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In process control environments, establishing communication with modular skids requires manual reconfiguration of network settings, which is inefficient and interrupts the workflow of technicians due to restrictive access control policies that demand specific static IP addresses for secure connections.
Innovation Solution
A skid communicator tool that automatically detects and configures network settings by analyzing preconfigured settings associated with each skid, allowing seamless connection, disconnection, and reconnection to different skids and networks with minimal user input, using a communication interface, processors, and user interface components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual reconfiguration of network settings is performed to establish secure connections with skids, then connection security is maintained, but technician workflow efficiency deteriorates due to time-consuming manual configuration
Solution Approach 1:
The communicator tool automatically performs network configuration by detecting skid network settings and self-adjusting its own network parameters without requiring technician intervention. This self-service capability maintains security requirements while eliminating manual configuration time
Solution Approach 2:
Multiple preconfigured network setting profiles are stored in the communicator tool before field use. When connecting to a skid, the tool rapidly switches between these pre-prepared configurations based on detected skid identifiers, eliminating the need for technicians to manually configure settings during workflow
2Reliability
If static IP addresses are required for secure skid connections, then network security is improved, but device adaptability deteriorates as technicians must manually adjust settings for different skids
Solution Approach 1:
The communicator tool dynamically adapts its network configuration by automatically detecting the target skid's network settings and adjusting its own IP address and communication parameters in real-time. This dynamic behavior allows the device to work with different static IP requirements across multiple skids without sacrificing security
Solution Approach 2:
The tool stores multiple preconfigured network parameter sets corresponding to different skids. Based on detected skid identifiers, the tool automatically switches between these parameter sets, changing its network parameters to match the required static IP configuration for each specific skid while maintaining security compliance
3Speed
If multiple preconfigured network settings are stored for different skids, then connection speed is improved, but device complexity increases
Solution Approach 1:
The processor acts as an intermediary that automatically manages the complexity of multiple network configurations. It detects skid identifiers, matches them to appropriate preconfigured profiles, and executes the correct configuration without exposing this complexity to the user. The user simply connects to any skid while the system handles the configuration matching automatically

AI summary
The described techniques enable a skid communicator tool to quickly change network settings to those required by a particular skid or network in a process control environment with which a user of the tool wishes to establish communication. These techniques are helpful because skids and networks in process control environments often require different network settings for any device attempting to communicate with the skids or network, and a user often must manually load these network settings every time she wants to communicate with a different network or skid. By contrast, the techniques enable the skid communicator tool to seamlessly connect to, disconnect from, and reconnect to any of the skids or other networks requiring different network settings with minimal input from the user, thus enabling a user to easily move through and interact with different areas, units, or equipment of the process control environment.
