Network Management Protocol Analysis for Slave Apparatus Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial network systems, when a slave apparatus is added or replaced, determining a common communication protocol between the master and slave apparatuses is challenging, leading to manual analysis and potential software application errors due to the lack of automated protocol compatibility checking.
Innovation Solution
A network managing program executed by the master apparatus that generates request commands to retrieve system description information from the slave apparatus, identifies compatible protocols, and switches communication software to ensure protocol compatibility using SNMP, eliminating the need for manual protocol analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual protocol analysis and software selection is performed, then protocol compatibility can be verified, but time consumption and potential for human error increase
Solution Approach 1:
The master apparatus automatically performs protocol analysis and software selection in advance before slave apparatus introduction, preparing the communication environment proactively so that when a slave apparatus is added or replaced, the appropriate communication software is already configured and ready, eliminating manual setup time
Solution Approach 2:
The master apparatus autonomously executes protocol compatibility verification and communication software selection without human intervention, using automated procedures to analyze protocols and select appropriate software based on the slave apparatus type, thereby reducing both time consumption and human error
2Loss of information
If manual protocol analysis is performed, then protocol information can be obtained, but the risk of software application errors increases
Solution Approach 1:
The master apparatus automatically analyzes protocols and selects communication software without human intervention, using automated procedures that eliminate subjective judgment errors and ensure consistent, accurate software selection based on the specific slave apparatus type
Solution Approach 2:
The system uses feedback from protocol analysis results to automatically determine the appropriate communication software, creating a closed-loop process where protocol information is analyzed and directly used to select the correct software configuration, reducing errors from manual interpretation
3Productivity
If automated protocol detection is implemented, then setup time is reduced, but system complexity increases
Solution Approach 1:
The master apparatus incorporates a universal protocol analysis capability that can handle multiple slave apparatus types and protocols through a single automated system, using a standardized approach that works across different device types without requiring separate manual procedures for each

AI summary
A conventional network managing method has a problem that there is a high possibility that a setting error of communication software occurs. According to one embodiment, a non-transitory computer-readable medium including a network managing program is executed in a master apparatus, system information stored in a slave apparatus in advance is read out in a procedure conforming to an SNMP, protocol information in which a communication protocol that can be used by the slave apparatus is described is read out from the slave apparatus by using an object ID described in the system information thus read out, and the protocol information thus read out is referred to start communication with the slave apparatus by executing software corresponding to the communication protocol.
