PURPOSE:To easily set and change data of an arithmetic block by storing the block numbers of the arithmetic blocks in storage devices that controller have respectively, and grouping the arithmetic blocks in one for every controller. CONSTITUTION:A data setter DSC1 sets data of a master controller 2, a subloop controller 3, and an input processing controller 4. Those controllers 2, 3 and 4 are connected to a common serial transmission bus 23, and transmission and reception of data among the controllers are carried out through the serial data transmission bus 23 under a transmission command from a bus controller 22. Each controller consists of a central processor for arithmetic processing, a storage device stored with arithmetic processing contents and the result of the contents, a bus for data transfer, a process input and output equipment as an input and output interface for a process signal, and a transmission interface for other controllers. |
