Integrated control system to control addressable remote devices
First Claim
1. A control system providing communication between an asset management system and a plurality of addressable remote devices, wherein said plurality of addressable remote devices are used to implement a manufacturing process, said control system comprising:
- a software component coupled to receive a plurality of commands for said plurality of addressable remote devices from said asset management system, said software component forwarding each of said plurality of commands to a corresponding one of said plurality of addressable remote devices.

Abstract
A multiplexer implemented substantially in the form of software, which enables the multiplexer to be integrated with a supervisory platform into one unit is disclosed. The multiplexer may contain a database which stores a mapping of the address of the devices to the corresponding port/channels to which the devices are connected. An emulation block implemented in software examines the address in each command/response and forwards the command/response appropriately. Due to the software implementation, some of the commands may be blocked (from being forwarded). According to another aspect, data required to generate a response may be retrieved from a controller block (instead of retrieving from the device), thereby reducing the overhead on the devices.

14. A computer readable medium carrying one or more sequences of instructions for causing a system to emulate a multiplexer, said multiplexer being provided between an asset management system and a plurality of addressable remote devices, wherein execution of said one or more sequences of instructions by one or more processors contained in said system causes said one or more processors to perform the actions of:
-
receiving a plurality of commands from said asset management system; and
forwarding each of said plurality of commands to a corresponding one of said plurality of addressable remote devices. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A multiplexer provided between an asset management system and a plurality of Addressable remote devices, said multiplexer comprising:
-
an asset manager interface receiving a plurality of commands from said asset management system; and
an emulation block implemented in the form of software instructions, said emulation block receiving each of said plurality of commands and determining a specific one of said plurality of Addressable remote devices to forward the corresponding command, and forwarding the corresponding command to said specific one of said plurality of addressable remote devices. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)
