Abstract
PURPOSE:To eliminate to fix a terminal equipment address and to dynamically set the address from a bus control device by sending the terminal equipment address from the bus control device as a command signal. CONSTITUTION:A terminal equipment address setting command signal, which is sent from the bus control device, enters a receiving circuit 7 from a data bus 1. The received command is recognized by a command recognizing circuit 13 and sent to an AND circuit 15 as the command signal. In case 18a that an address is set to the terminal equipment of a high order and in case that the output signal of an FF 16 is not significant, the load signal of a terminal equipment register is generated in the circuit 15 and the terminal equipment address is set. Simultaneously, a terminal equipment address set completing signal is set to the FF 16 and outputted to the terminal equipment of a low order. Accordingly, the terminal equipment address can be dynamically set from the bus control device.
