Engineering Contradiction Analysis
1Ease of manufacture
If data areas of fixed size are allocated to all nodes in a transfer memory system, then data exchange can be performed uniformly among all nodes, but utilization efficiency of the data areas becomes low and the number of connectable nodes is constrained
Solution Approach 1:
The patent segments the data area allocation by creating separate data areas for different node types (master nodes and slave nodes) rather than using a uniform allocation for all nodes. This allows each segment to be optimized for its specific node type, improving overall utilization efficiency while maintaining uniform data exchange mechanisms within each segment.
Solution Approach 2:
The patent applies local quality by assigning different data area characteristics to different nodes based on their roles. Master nodes and slave nodes have differently configured data areas tailored to their specific communication needs, allowing each node to have optimal data area properties for its function rather than a one-size-fits-all approach.
2Productivity
If a plurality of communication ports are provided to speed up communication, then communication capacity increases, but it becomes difficult to manage nonuniformity in correspondence between control application data and control target devices
Solution Approach 1:
The patent introduces a communication control unit as an intermediary that manages the plurality of communication ports. This intermediary component handles the complex mapping between control application data and control target devices, centralizing the management logic and reducing the overall system complexity despite having multiple communication ports.
Solution Approach 2:
The communication control unit is designed with multi-functional capabilities to handle various communication tasks across multiple ports including data routing, mapping, and coordination. This universal component can perform multiple functions that would otherwise require separate specialized components, simplifying the management of nonuniformity in data correspondence.
3Device complexity
If data areas are allocated in equal size on address space for all nodes, then address space management becomes simple, but the number of connectable nodes is likely to be constrained
Solution Approach 1:
The patent segments the address space into distinct regions for master nodes and slave nodes, with each segment having appropriate size and characteristics for its intended use. This segmentation allows the system to support a larger number of nodes with diverse requirements while maintaining organized and manageable address space allocation.

AI summary
A control communication system and a plasma processing apparatus for efficient utilization of a computer resource and a communication resource such as a storage area. A control communication system includes a control communication apparatus that includes a communication unit configured to transmit a packet including control data and in which the communication unit includes a plurality of ports, and a plurality of device groups that are communicably connected to the plurality of communication ports and are operated according to the received packet. The control data is generated toward a target communication port among the plurality of communication ports, the target communication port being determined based on information of a communication port that transmits the packet. The packet includes a packet data area in which the control data is arranged, and is transmitted from the target communication port to the device group connected to the target communication port.
