PURPOSE:To give an interlock information without transferring unnecessary information, by changing the interlock information to a serial signal, and also giving a constant rule for an information transfer to the controller to which said signal has been connected in a loop. CONSTITUTION:Serial interface cards 461-463 are constituted in a loop, and from each card, the information is sent out by adding its own interlock information, and also the interlock information of other necessary card is inputted to a processor of a microsequencer related to itself, through a bus. A timing signal in this case performs its duty by the fact that a shift signal and a write strobe signal flow in a loop. According to this constitution, unnecessary information which is left by shift in 1 cycle matters little, and also the wiring work cost is reduced. |
