PROBLEM TO BE SOLVED: To make applicable to an application that can terminate a necessary process within a prescribed arithmetic cycle even in a highly loaded state and is required of immediate response.SOLUTION: Field apparatuses 1-5 calculate a load factor every arithmetic cycle, and a host device 7, upon receiving a request for distributed processing based on the processing load state in a prescribed arithmetic cycle from the field apparatus 1, for example, inquires of the field apparatuses 2-5 about the possibility of whether distributed processing can be accepted, assigns an arithmetic load to the field apparatuses 2-4 which have responded on the basis of their own processing load state in the inquired arithmetic cycle that the distributed processing can be accepted, and transmits the arithmetic result obtained from the field apparatuses 2-4 to the field apparatus 1. Then, the field apparatus 1 incorporates the arithmetic result received from the host device 7 into a prescribed arithmetic cycle. |
