Abstract
Abstract A method of continuously self configuring a distributed control system. The method comprises scanning a plurality of potential address codes to locate an active object (13). Software senses an identity code (17) which is associated with the active object (13). Then a machine map (14) is built which provides the current address code (15, 31) of the active object (13). Within a network (28), a network map (21) is constructed by getting information from the appropriate machine map (14) for each computer (23). The network map (21) provides the current network address (32) of each active object (13) available to the network (28).

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
213 words
A method of continuously self configuring a distributed control system, comprising: providing at least one object with an identity code; providing at least one control computer; communicating between the object and the control computer using a predetermined address code; providing a configuration map having detailed information concerning function and capabilities of each object which is expected to be active; running an inventory process on the control computer; getting information from the configuration map by the inventory process; sensing the identity code of any object which is in an active state by the inventory process; building a machine map which contains at least the object's identity code, the object's address code, and a copy of the detailed information from the configuration map; building a network map to reflect the current contents of all machine maps within the network; revising the machine map according to a first predetermined schedule to add any object which is newly in an active state; further revising the machine map to reflect any changes in the detailed information from the configuration map; removing the machine map entry for any object which is not in an active state; and revising the network map according to a second predetermined schedule to reflect the current contents of all machine maps within the network.
Claim 2
Independent Claim
213 words
A method of continuously self configuring a distributed control system, comprising: providing at least one object with an identity code; providing at least one control computer; communicating between the object and the control computer using a predetermined address code; providing a configuration map having detailed information concerning function and capabilities of each object which is expected to be active; running an inventory process on the control computer; getting information from the configuration map by the inventory process; sensing the identity code of any object which is in an active state by the inventory process; building a machine map which contains at least the object's identity code, the object's address code, and a copy of the detailed information from the configuration map; building a network map to reflect the current contents of all machine maps within the network; revising the machine map according to a first predetermined schedule to add any object which is newly in an active state; further revising the machine map to reflect any changes in the detailed information from the configuration map; removing the machine map entry for any object which is not in an active state; and revising the network map according to a second predetermined schedule to reflect the current contents of all machine maps within the network.
Claim 3
Independent Claim
97 words
A method of continuously self configuring a distributed control system, comprising: scanning a plurality of potential address codes to locate an active object; sensing an identity code which is associated with the active object; building a machine map which includes at least a current machine address which is associated with the active object; building a network map by getting information from the machine map, the network map providing at least a current network address of the active object; and repeating the above steps until all active objects are reflected in the machine map and the network map.
Claim 4
Independent Claim
97 words
A method of continuously self configuring a distributed control system, comprising: scanning a plurality of potential address codes to locate an active object; sensing an identity code which is associated with the active object; building a machine map which includes at least a current machine address which is associated with the active object; building a network map by getting information from the machine map, the network map providing at least a current network address of the active object; and repeating the above steps until all active objects are reflected in the machine map and the network map.
Claim 5
Dependent Claim
37 words
The method of continuously self configuring a distributed control system of claim 2 further comprising: sensing an object which is no longer active; and revising the machine map to remove the object which is no longer active.
Claim 6
Dependent Claim
33 words
The method of continuously self configuring a distributed control system of claim 2 further comprising: sensing a previously inactive object which becomes active; and revising the machine map to add the active object.
Claim 7
Dependent Claim
29 words
The method of continuously self configuring a distributed control system of claim 2 wherein the machine map further comprises additional detailed information concerning a function of the active object.
Claim 8
Dependent Claim
29 words
The method of continuously self configuring a distributed control system of claim 5 further comprising: revising the machine map to reflect physical and operational changes to the active object.
Claim 9
Dependent Claim
29 words
The method of continuously self configuring a distributed control system of claim 2 further comprising: resolving hardware requirements for a desired task by getting information from the network map.
Claim 10
Dependent Claim
31 words
The method of continuously self configuring a distributed control system of claim 2 further comprising: revising the network map to ensure that it reflects accurately the contents of each machine map.
Claim 11
Dependent Claim
114 words
A continuously self configuring distributed control system comprising: an identity code which is associated with an active object and serves to uniquely identify the active object within a network; an inventory process which senses the identity code and an associated address code for the active object; a machine map, created and revised by the inventory process, which comprises a cross reference between at least the identity code and the associated address code for the active object; a supervisory process; and a network map based on the machine map which is created and revised by a supervisory process and provides a current network address code for the active object upon request by a user process.
Claim 12
Dependent Claim
114 words
A continuously self configuring distributed control system comprising: an identity code which is associated with an active object and serves to uniquely identify the active object within a network; an inventory process which senses the identity code and an associated address code for the active object; a machine map, created and revised by the inventory process, which comprises a cross reference between at least the identity code and the associated address code for the active object; a supervisory process; and a network map based on the machine map which is created and revised by a supervisory process and provides a current network address code for the active object upon request by a user process.
Claim 13
Dependent Claim
50 words
The continuously self configuring distributed control system of claim 9 further comprising: means for resolving a hardware requirement for a desired task by getting information from the network map; and means for allowing the desired task to control an item of required equipment by getting information from the network map.
Claim 14
Dependent Claim
30 words
The continuously self configuring distributed control system of claim 9 further comprising: a configuration map having detailed information concerning a capability of an object which is expected to be active.
Claim 15
Dependent Claim
