PURPOSE:To perform the control and protection of a load such as a motor, etc., based on provided functional data, by alarming in case of mismatch as a result of comparison between the returned functional data and the provided functional data. CONSTITUTION:Inputted functional data is transmitted from a communication means 32 of a data remote provision device 31 to a control device 29 through a transmission line 33 and sent to a memory section 40 to be stored. Various kinds of functional data thus stored to the memory section 40 are read with a logic arithmetic circuit 34, returned to the communication means 32 of the data remote provision device 31 from a transmission section 30b of a communication means 30 and sent to a data monitoring section 44 from a receiving section 32b. Then, the data monitoring section 44 compares them with the functional data of the corresponding control device 29 stored in a central memory section 43 and sends in an alarm by actuating an alarm section 46 in case they are mismatched. |
