Engineering Contradiction Analysis
1Loss of energy
If multiple command data sets are transmitted individually between host control device and control device, then process execution control is achieved, but communication cost increases
Solution Approach 1:
The patent combines multiple individual command data set transmissions into a single bulk transmission operation. The host control device transmits multiple command data sets simultaneously through a unified communication interface, merging what would otherwise be separate communication events into one efficient operation, thereby reducing communication cost while maintaining process execution efficiency
Solution Approach 2:
The host control device prepares and buffers multiple command data sets in advance before transmission. By pre-organizing the command data sets and having them ready for bulk transmission, the system eliminates the need for repeated individual transmission operations, reducing communication overhead while ensuring processes can be executed efficiently
2Speed
If frequent data transmission is performed between host control device and control device, then real-time process control is achieved, but communication overhead increases
Solution Approach 1:
The patent merges multiple small-data transmissions into one bulk transmission operation. By combining multiple command data sets into a single transmission event, the system maintains real-time control capability while significantly reducing the cumulative communication overhead that would result from frequent individual transmissions
Solution Approach 2:
The bulk transmission mechanism enables continuous process control without interruption. The control device receives multiple command data sets in one operation and executes them sequentially, maintaining continuous useful action (process control) while eliminating the repeated start-stop patterns of frequent individual transmissions that create communication overhead

AI summary
[Problem to be solved] To reduce communication cost when a host control device causes a control device to execute various processes. [Solution] In a production system (1), a control device (30) controlling at least one industrial device (40) and a host control device (20) capable of controlling the control device (30) are communicably connected. The host control device (20) includes: a register part (201) that has a register that is allocated for controlling the control device (30) and includes a command area; and a transmission part that transmits to the corresponding control device (30) multiple command data sets written in the command area. The control device (30) includes: a communication storage part (301) in which multiple command data sets received from the host control device (20) are written; and an execution part (302) that executes a process instructed by the host control device (20) based on the multiple command data sets written in the communication storage part (301).
