Innovation Solution
A modular control system that integrates configurable safety devices with user-programmable logic, using a platform bus with auto-addressing capabilities, allowing modules to be dynamically assigned addresses based on their physical position, and supporting multiple communication protocols for flexible and secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual addressing of modules is used on a platform bus, then address assignment is simple and direct, but system complexity increases and installation time is extended
Solution Approach 1:
The module automatically determines its own address by detecting its position on the platform bus and assigning itself an address without external intervention. The master module sends address assignment signals through the identification signal line, and each slave module autonomously captures the signal and configures its address based on the received information, eliminating the need for manual address configuration.
Solution Approach 2:
The system performs address assignment automatically during the module initialization phase before the system becomes operational. The master module proactively sends address assignment signals to slave modules as they are detected on the bus, preparing the addressing configuration in advance rather than requiring manual setup during installation or commissioning.
2Stability of the object's composition
If fixed addressing is used for modules, then configuration is stable, but adaptability to different module positions is reduced
Solution Approach 1:
The addressing system transitions from a static fixed addressing scheme to a dynamic automatic addressing scheme. Slave modules can be added, removed, or repositioned on the platform bus, and the master module automatically detects changes in module positions and reassigns addresses accordingly through the identification signal line, maintaining system stability while adapting to configuration changes.
Solution Approach 2:
The system changes the addressing parameter from a predetermined fixed value to a dynamically assigned value based on module position. The master module varies the address assignment according to the detected position of slave modules on the bus, allowing the addressing parameter to adapt to different physical configurations while maintaining systematic organization.

AI summary
A system and approach for addressing modules on a platform bus that may incorporate a master module and one or more slave modules. The platform bus may run through sub-base connectors that interlock modules together on a rail. Addressing of the modules may occur automatically and dynamically in that the master module may have a first address by default, and a first slave module adjoining the master module may be assigned a second address. A second slave module adjoining the first slave module, if there is one, may be assigned a third address. Each of the other slave modules, adjoining a preceding slave module assigned an address, may be assigned a next address after an address assigned to a preceding slave module. Addresses may be assigned in a numerical order to each module based on a physical position of the respective module on a rail.
