Abstract

PURPOSE: To collect data efficiently with a remote operation from a computer, by a data collector provided at each data transmission and reception device correspondingly and a data buffer circuit storing the data.
CONSTITUTION: Data transmission and reception via a computer system and a switching circuit 5 is made at a receiver/driver circuit section 13 and the data transmission/reception with a data transmission/reception device 19 is made at a receiver/driver circuit section 20. Data from each direction is temporarily stored in a data buffer circuit section 14. The control of operation from a computer system is made by a control circuit section 15. The control of the operation from data transmission/reception devices 2W4 and operation panel sections 10W12 is made by interpreting addresses inputted to a control circuit section (1)20 and a data buffer circuit section (2)14 and providing an address decoding circuit section 16 transmitting a signal selecting data collection circuit sections 7W9 to a switching circuit section controlling section 6. A data buffer 18 stores the collected data even at line interruption with the computer system.
