Abstract
A remote station is configured to convey instructions to a central station. The remote station receives a plurality of input commands to effect an operation at said central station, stores them sequentially in a cache and asynchronously conveys them to the central station. If the remote station receives an error message from the central station indicating that an unexpected event was detected, the remote station identifies a set of sequential cached input commands and sequentially re-conveys them to the central station so as to determine if one of them was the cause of the unexpected event.
Claims19
A method of instructing an operation to be performed at a central station from a remote station, comprising the steps of:
- receiving a plurality of input commands at said remote station to effect an operation at said central station;
- storing said input commands sequentially in a cache at said remote station, to create a plurality of stored input commands;
- asynchronously conveying said input commands from said remote station to said central station;
- receiving, at said remote station, an error message from said central station indicating that an unexpected event was detected;
- identifying a set of input commands, wherein said set comprises a sequential plurality of said stored input commands;
- and
- sequentially re-conveying said set of input commands from said cache to said central station so as to determine if one of said set of input commands was the cause of said unexpected event.
A remote device configured to convey instructions to a central station, comprising:
- an input device for receiving input commands;
- a processor configured to asynchronously convey said input commands to a central station;
- and
- a cache for sequentially storing said input commands;
- wherein said processor is configured to replay a sequential plurality of said commands from said cache to repeat an input driven sequence.
A central station configured to receive input commands from a remote station, comprising a processor, storage and a communication channel;
- wherein said processor is configured to:
- receive, via said communication channel, input commands from said remote station;
- process asynchronously said received input commands;
- act upon said received input commands;
- and
- identify an unexpected event and instruct said remote station to replay previously received input commands,
- whereupon said remote station reads said previously received input commands from a cache and replays a sequential plurality of said input commands.
