PURPOSE:To minimize a dead time of a processing system, by providing a transmitter between an upper-order processor and a terminal processing system. CONSTITUTION:A transmitter is connected to an upper-order processor consisting of a global memory, an upper-order computer and an upper-order coupling device and also to a plurality of terminal input and output devices. Register groups 35 and 37 are provided at each terminal device so that the information of the terminal device can be written in and read out arbitrarily. Multiplexers 31 and 32 sequentially select the content of the register groups 35 and 37 and output it to a plant controller 33. On the other hand, a logic controller 34 outputs an instruction signal to the multiplexers 31 and 32. Thus, the terminal processing system makes the decentralized processing, collects the information and the upper-order processor can make the operation processing in high speed and accuracy. |
