<p>PURPOSE:To improve the response without increasing a data transmission speed by dividing a data transmission line and sending and receiving a data for a same frame period. CONSTITUTION:Plural terminal controllers are grouped into two groups A, B and they are connected to a master controller 1 via independent buses A, B. The master controller 1 receives a data in terminal controllers 2B - of a group B through a bus B nearly at the same time when the master controller 1 sends a data to one of terminal controllers 2A - of a group A through a bus A, and conversely the master controller 1 receives a data from one of terminal controllers 2A-of the group A through the bus A nearly at the same time when the master controller 1 sends a data to one of terminal controllers 2B - of the group B through the bus B.</p> |
