- each of the FPGAs 21 from companies A, B, and C is implemented with multiple functional logics that control sensor circuits 32 and motor circuits 33 from multiple manufacturers that are implemented on a base substrate 30 developed for each device.
- the multiple functional logics implemented in the FPGA can be designed as a common program by using RTL (Register Transfer Level) design, which allows common design regardless of the FPGA manufacturer.

In this way, even if it becomes difficult to obtain FPGAs made by company A, product manufacturing can continue by implementing FPGAs made by companies B and C in the expansion module 20.
- the FPGA 12 mounted on the core module 10 can be any FPGA from multiple pre-designated manufacturers. In this way, even if it becomes difficult to obtain FPGAs from company A, product manufacturing can continue by mounting FPGAs from companies B and C on the core module 10.
