An interface modulerelays control signal communication between a main CPUand a light source control CPUand between the main CPUand a camera head CPU. The interface moduleincludes an FPGAhaving CPU I/Fstothat correspond to communication schemes of CPUs, and, respectively, and first and second storage units() and(). The FPGArelays a control signal between the main CPUand the light source control CPUand between the main CPUand the camera head CPU, while temporarily storing the control signal in the first and the second storage units() and(). Moreover, a first communication timing and second and third communication timings are set at timings shifted from one another.

In a data management unit in a computer system, the computer system has a computer in which the data management unit is incorporated, and a terminal intercommunicates with the computer. In the data management unit, an object data storage unit (memory) stores in addresses thereon data items to which the terminal is adapted to make access. A parameter management file stores thereon parameters concerning a data structure of each data item. The parameters include a data name of each data item, a data type of each data item, an address related to each data item on the data storage unit and an array information of at least one data item. Then at least one data item has an array structure, and the array information includes a number of the array elements. On a number of bytes definition table, a number of bytes corresponding to each data type of each data item is stored. A data table producing module is adapted to make, according to the parameters concerning the data structures of the data items of the numbers of bytes of the data types, an address related to each data item in array element units on the memory (data storage unit) correspond to each data name of each data item so as to produce a data table.

In the electric power system protective control system, a plurality of protective control apparatuses each having a protective control function to an electric power system are distributed and connected through a communication network to each other so that data communication is permitted among the respective protective control apparatuses. Each of the protective control apparatuses is carried out a process of executing a control operation related to the protective control function of the own apparatus according to a program module. The program module migrates through the communication network to the own apparatus along a predetermined route of migration. Each of the protective control apparatuses executes a process of migrating the program module from the own apparatus to another protective control apparatus. The another protective control apparatus is determined to a next destination of migration according to the route of migration. In a case where the program module is not migrated by the migration process to the next destination protective control apparatus, each of the protective control apparatuses executes a process of changing a next destination of migration of the program module to a predetermined protective control apparatus except for the next destination protective control apparatus, making it possible to prevent the program module from stopping.
