NETWORK CONTROL UNIT, CONTROL TERMINAL AND NETWORK TERMINAL

摘要

PROBLEM TO BE SOLVED: To deal with a dynamic change in the operating environment of a network terminal by transmitting the information of a changed operating component from the network terminal to a control terminal and providing the operating environment reflected with the changed operating component by the control terminal. SOLUTION: Operating information is transmitted from a network terminal 13 to a control terminal 11. When a change on a present program table is detected in the network terminal 13, a central processing unit 133 transmits the operating information of an operating component identifier from bidirectional communication equipment 131 The control terminal 11 receives the operating information by bidirectional communication equipment 116, a central processing unit 115 receives the operating information from the bidirectional communication equipment 116, downloads it to a volatile information processor 112 and analyzes it later and the operating environment is reflected with the information. The operating information of the operating component identifier on a volatile information storage device 112 is replaced with new operating information and the information of operating component of the operating component identifier is deleted.
