Abstract
Abstract A method and apparatus for communication with a remote device 250 by a node system 200 and a SCADA system 100. The SCADA system 100 communicates with the remote device without protocals or characteristics of the remote device 250 or the communication channel 270 connecting the remote device to the node system. A display 250 may monitor the communication channel 270 and may be remotely located with respect to the node system 200. The node system 200 may schedule the input from the remote device 250 by setting an interval and duration so that the input may be transmitted.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
78 words
A status change data gathering apparatus comprising: a status change detector for detecting and transmitting data representing changes in a process or apparatus; a first processor connected to said status change detector through a communication channel for receiving and collecting said detected data representing said changes in said process or said apparatus; a second processor connected to said first processor, said second processor communicating to said status change detector through said first processor independently of said communication channel.
Claim 2
Dependent Claim
78 words
A status change data gathering apparatus comprising: a status change detector for detecting and transmitting data representing changes in a process or apparatus; a first processor connected to said status change detector through a communication channel for receiving and collecting said detected data representing said changes in said process or said apparatus; a second processor connected to said first processor, said second processor communicating to said status change detector through said first processor independently of said communication channel.
Claim 3
Dependent Claim
25 words
A status change data gathering apparatus as in claim 1, wherein said second processor communicates with said status change detector to collect said detected data.
Claim 4
Dependent Claim
28 words
A status change data gathering apparatus as in claim 1, wherein said second processor communicates with said status change detector by the communication procedure of said first processor.
Claim 5
Dependent Claim
85 words
A status change data gathering apparatus comprising: a status change detector for detecting and transmitting data representing changes in a process or apparatus; a first processor connected to said status change detector through, a communication channel for receiving and collecting said detected data representing said changes in said process or said apparatus; a second processor connected to said first processor, said second processor communicating to said status change detection by controlling said first processor to communicate with said status change detection through said communication channel.
Claim 6
Dependent Claim
85 words
A status change data gathering apparatus comprising: a status change detector for detecting and transmitting data representing changes in a process or apparatus; a first processor connected to said status change detector through, a communication channel for receiving and collecting said detected data representing said changes in said process or said apparatus; a second processor connected to said first processor, said second processor communicating to said status change detection by controlling said first processor to communicate with said status change detection through said communication channel.
Claim 7
Dependent Claim
25 words
A status change data gathering apparatus as in claim 4, wherein said second processor communicates with said status change detector to collect said detected data.
