Abstract
Abstract A programmable terminal is disclosed in which a non-volatile memory in combination with decoding logic enables data collection and control of external devices. The memory can be programmed prior to assembly into the terminal or erased and programmed either on- or off-line. The terminal logs data in its entirety or only that data meeting programmed criteria. Specific examples of the use of the programmable terminal of the present invention are also disclosed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
142 words
A programmable terminal for operating on-line or off-line to control or monitor a plurality of external devices comprising: memory means for storing program and control information; logic means coupled to said memory means and said external devices for converting information from said memory into control signals, said logic means including external selection means for selectively activating at least one of said external devices; comparison means coupled to said memory means and said external devices for comparing incoming information with information from said memory means; internal selection means, coupled to said memory means and said external devices, for selecting one of a plurality of internal signals for transmission from said terminal, said internal signals including said control signals and signals received from selectively activated external devices; and output means, coupled to said internal selection means, for providing an output signal from said terminal.
Claim 2
Dependent Claim
142 words
A programmable terminal for operating on-line or off-line to control or monitor a plurality of external devices comprising: memory means for storing program and control information; logic means coupled to said memory means and said external devices for converting information from said memory into control signals, said logic means including external selection means for selectively activating at least one of said external devices; comparison means coupled to said memory means and said external devices for comparing incoming information with information from said memory means; internal selection means, coupled to said memory means and said external devices, for selecting one of a plurality of internal signals for transmission from said terminal, said internal signals including said control signals and signals received from selectively activated external devices; and output means, coupled to said internal selection means, for providing an output signal from said terminal.
